Avastu Blog: Sustainable Global Clouds

We held a very successful press conference in Kampala, Uganda and later on handed out the workshop certificates to our candidates. The press was very curious about the "Green Grid" so I have also handed out some copies of it to them. I will provide the link if the Ugandan Daily when they publish our news.

I used the VMware Tools v1.0.3-44356 provided by VMware Server v1.03. This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web. This document comes without warranty of any kind! I want to say that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you! Nice work, HowToForge! Link.

Citrix at a high load can be a demanding application due to high kernel-resource utilization and a high level of context switches associated with its underlying Terminal Server architecture. But in many environments this high utilization often doesn't occur. Many times, application conflicts -- or the need for security isolation among applications or users -- force a horizontal scaling of Citrix servers. These kinds of applications or users that can't cohabitate on a single server can result in an organization buying new Presentation Servers even though existing server utilization is low. In a virtualized environment, multiple server instances are enabled to run on the same physical server chassis. When application conflicts or security requirements force additional servers to be brought online, virtualization can enable it to be done with relative ease. You can copy and paste new servers to your heart's content until the hardware resources of your physical chassis max out.

Infrastructure virtualisation will be the dominate technology in datacentres within the next few years, thanks to the convergence of three significant factors in the global economy, according to analyst firm Butler Group. Virtualisation is the practice of running a layer of software on a server that allows multiple operating systems and environments to run on the same piece of hardware as if they were separate physical servers. virtualisation allows computing resources to be used more efficiently and also allows much greater flexibility in managing and allocating these resources. Many vendors are touting the benefits of virtualisation, and it is perhaps no surprise then that Butler thinks the technology is set to dominate the datacentre. The three factors influencing this, says Butler in its report, "Infrastructure virtualisation," are the need for organisations to reduce their energy consumption and carbon footprint; the increasing need of being able to respond quicker to ma

VAR AN4 Group plans to increase turnover by 20 per cent in the coming year after becoming a fully accredited partner of virtualisation vendor VMware. The reseller has enjoyed a successful period of late, signing lucrative agreements with vendors in the security sector. Turnover also soared to £15m last year, an increase of 12 per cent, and AN4 is adamant that it is on track to surpass this in 2007. “We have made a significant investment to gain the accreditation,” confirmed Kristian Connor, sales director at AN4. “We have set a target to increase turnover by 20 per cent in the next year and through being accredited, we are well on our way to achieving this.

A better idea is to adopt something called virtualisation—a technique that’s been around for ages, but has only lately come back into fashion. Virtualisation provides a way of hiding a computer’s resources—its central processor, operating system, internal memory, network controller, and storage devices—behind a software curtain. The idea is to give users (not to mention nefarious strangers) the impression they have control of the machine, when really they are dealing with a simulacrum created entirely in software. The technique was invented by IBM back in the 1960s, when software was relatively cheap and hardware incredibly expensive. By using virtualisation, one costly mainframe could be partitioned so as to run many different applications all at the same time—each within its own “virtual machine” in a layer of software running on top of the physical machine’s actual operating system. With modern hardware so cheap, Intel-based servers that dish out applications and data have prolifera

"It's sometimes called grid," he said. "But at it's simplest it's about running virtual application components over a heterogeneous pool of devices at low management cost." UBS first started using application virtualisation techniques in 2002, but now has a sophisticated pool of global computing resource with which to run and dynamically provision its most CPU-intensive risk simulations and calculations. Morgan said that, in this time, the internal development of frameworks and management tools has been key to getting business buy-in that sees different functional areas and geographical regions dynamically sharing their IT resources around the clock.

KVM emerged out of an Israeli company, Qumranet, last year as lead developer Avi Kivity posted 12,000 lines of code to a Linux kernel mailing list. The Oct. 19 post "came out of nowhere" and was added to the kernel after a review of "just a few months," said Jonathan Corbet, kernel developer and author of the Linux Weather Forecast, a Linux Foundation update on weekly kernel developments, in an interview. "It looked like it was kernel-ready on day one. It was an exceptional patch in many ways," said Andrew Morton, Linux kernel maintainer and one of Linux Torvalds' top lieutenants. By "patch," Morton means a donation of new code, not a bug fix or repair of existing code. The kernel developers didn't know Kivity from previous contributions -- he hadn't made any. Nor was there good information available on his company. "I went to the Qumranet Web site. It didn't tell me much," said Morton. Qumranet, a venture capital backed

A Q&A with a Burton Group analyst: Q: Does storage virtualization really reduce administrative overhead the way the vendors claim it does? A: No, not necessarily. What it does is move the work from one place, the individual arrays, to another place, the centralized console of the virtualization product. But administrators still have to perform the same day-to-day chores such as volume management, data replication and migration. However, virtualization can certainly make your life much easier if you're running a mixed-vendor storage environment. In that case the only thing you have to do on each vendor's specific console is initial configuration, then after that you do everything from the centralized console. Read on...

A new set of challenges Without the tools to optimize and manage end-to-end virtualization, IT is unable to do system-wide capacity planning, lacks visibility into server and storage resource allocation and utilization, has difficulty troubleshooting and managing change, and can no longer carry out historical analysis. The impact can be severe. Challenge #1: System-wide capacity planning becomes impossible The data center exists to maximize application performance, and IT keeps service level agreements (SLAs) to track its success. Meeting service level objectives requires IT to optimize resource capacity and planning, but the growth of complexity in mixed environments has made this increasingly difficult to do. In an age where virtual machines can be created easily, manual capacity planning across the infrastructure becomes impossible. The inability to do accurate capacity planning forces IT to over-provision resources. This is particularly true with storage, but extends

Features and Benefits Comprehensive control - Veeam Monitor provides for single-screen detailed reporting and alerting of key usage and performance statistics, such as CPU, memory, disk, network, and swap usage for cluster, resource pool or virtual machine.

For small datacenters or development labs running without VirtualCenter, Veeam Monitor can still provide useful monitoring, alerting and reporting for multiple ESX servers. Historical reporting - Veeam Monitor collects and stores historical performance data for a period of up to one year. Using the HTML reporting functionality, you can generate graphical reports for any period of time. Reports include detailed graphs on CPU, memory, disk and network and swap usage swap usage

A desktop virtualization vendor that's been operating in stealth mode, Qumranet, has emerged as one of the first companies to make use of the KVM virtualization engine, already implanted in the Linux kernel. Few developers know much about KVM. It was added to Linux kernel 2.6.20 in October 2006. KVM is a hypervisor capable of making use of the virtualization assists built into the latestIntel (NSDQ: INTC) and AMD (NYSE: AMD) chips. Those hardware hooks simplify some of the complexity in the x86 instruction set, giving KVM a lean and mean profile at just 12,000 lines of code. Qumranet is offering one of the first virtualization products to be built on top of KVM. That may be because the lead KVM developer, Avi Kiviti, and several other developers are part of the startup, which has offices in Netanya, Israel, and Sunnyvale, Calif. Qumranet made its debut Monday at the Demofall 07 show in San Diego, emphasizing its desktop virtualization product, Solid Independent Computing Environmen

VMware is building support for Intel's FlexMigration assist for virtualized environments in VMware's Vmotion technology, which is used to move running virtual machines from one physical server to another. The collaboration is expected to help VMware customers move virtual machines to Intel's upcoming processors based on its 45nm scale process technology, Jake Smith of Intel's Advance Server Technology Group told InformationWeek. Intel is scheduled to ship in November its first 45nm server chip built using 45-nanometer technology, codenamed Penryn. That release is expected to be followed in 2008 with Nehalem, codename for Intel's upcoming microarchitecture. Read on...

In the article, Wolf said, “one significant issue with virtual machine security is with virtual switch isolation. The current all-or-nothing approach to making a virtual switch ‘promiscuous’ in order to connect it to an IDS/IPS is not favorable to security.” For example, “if you connect an IDS appliance to a virtual switch in promiscuous mode,” Wolf said, “not only can the IDS capture all of the traffic traversing the switch, but every other VM on the same virtual switch in promiscuous mode could capture each other’s traffic as well.” This statement ruffled some feathers at VMware, and they quickly emailed me and Burton to “educate us” and the VMware community that in fact, VMware allows (and encourages) users to configure only the ports they need to be promiscuous as such. This is not a per vswitch setting, but rather a per portgroup setting. The way to configure a vswitch for IDS/IPS is to create a separate portgroup from those used for normal VMs and configure it for “Promiscuous Al

That is massive, big daddy of all projects! That still left a large pool of virtualization candidates -- about 10,000 servers, in fact, most running either Windows or Solaris. In general, their utilization was low, particularly those used in development and test environments where, in both cases, the boxes tended to have more horsepower than needed. That low utilization is apparent in Hilton's expectations of how many VMs he will get per physical server: at least a 20:1 ratio for servers in the development environment; 15:1 to 10:1 for the test and disaster recovery environment; and 5:1 in the production application environment. Hilton's team is now in the process of virtualizing these servers, with plans to be done with 5,000 by early 2009. The group has already virtualized 1,000. In crafting Credit Suisse's server virtualization strategy, Hilton decided to take a page from the storage virtualization playbook and conceive of the environment as a shared service, not just as

Well, all the folks who have seen VMware grow in the past should hold on to their horses and appetite coz VMware is coming for the storage. VMware, Inc., the virtualization leader, today announced a new hardware certification program for storage virtualization devices. Combined with the virtualization-enabling technologies in VMware ESX Server, this program is designed to enable customers to have more choice in deploying virtualized storage solutions with VMware Infrastructure. “VMware is committed to working with our storage partners to offer customers the greatest choice of storage vendors when deploying virtualization across their organization’s infrastructure,” said Parag Patel, vice president of alliances at VMware. “As enterprises increasingly standardize their IT environments using virtual infrastructure, it is important to have a breadth of storage hardware options available to them.” By enabling hardware vendors to certify storage virtualization devices for VMware Infrastruc

The three pillars of IT computing, networking and storage have always been embraced in an odd dance of shifting functionality responsibility as Moore’s Law continues to break down, blur and redistribute lines of responsibility across the three pillars in an effort to increase application performance. For example, networking has always off loaded tasks that were once done by computers. In fact some of the first routers were DEC mini and micro VAX systems back in the early 80s. This trend continues today with more computer functions such as load balancing, caching, security and certain aspects of computer operations migrating to the network fabric. Access to and configuration of storage has gone through huge changes over the years, thanks to networking, with the introduction of Network Attached Storage (NAS) and Storage Area Network (SAN). Computing functionality, applications acceleration, storage access and many other functions have shifted into the network fabric. The latest shift is

In a step that may be seen to be extending a friendly hand to potential competitors, VMware announced the development of a standard called OVF (Open Virtualization Format) along with Microsoft, which is working on a virtualization product code-named Viridian and Xensource, the open source virtualization technology. The standard is aimed at easing the packaging and distribution of virtual machines. But Greene avers that VMware is ahead of the game than Microsoft citing that the latter's product doesn't support the live migration of virtual machines while they are running purportedly a very powerful feature in virtualization.

A survey of the vulnerabilities publicly disclosed in VMWare's popular virtualization software discovered that almost three-quarters of the 100 flaws discovered since 1999 were found in the last two years, Kris Lamb, director of IBM's Internet Security Systems' research group, stated Friday in a blog post. Nearly 60 percent of the vulnerabilities found could be exploited remotely, Lamb said. It cannot be stressed anymore that the second you are in the virtual world, you could very soon be lost. So if you aren't taking security seriously, you'er putting your data center at risk. Link

Automated I/O path failover, automatic array failure detection and rebuild using a standby hot spare are available out of the box. Premium features like snapshot technology and volume-copy functionality can be purchased as software upgrades. In the lab, we were very impressed with the simplicity of Dell's MD Storage Manager application. The Java-based management GUI was very simple to navigate and performed as quickly as a well-written client/server application.

I guess its Saturday and imaginations are flying. This L'Inq reporter thinks AMD can still save the ship. I didn't know that the ship was sinkin'! Option 1 AMD continues as it is, comes out of the doldrums, creates internal $$$ to repay the mounting debt, and Hector Ruiz becomes the new Steve Jobs-like IT hero figure. Option 2 IBM decides it is the time, and buys AMD as it is, lock stock and barrel. Benefits? It gains control of its own competitive X86 platform, with potential future socket compatibility with POWER7 for cross-platform shared infrastructure, sets up truly serious competition against Intel. Headaches? Well, what to do with the current management, and why should IBM bother repaying all those debts. Option 3 Samsung comes in, figuring out it should continue where it stopped in 2001 after the Alphacide. Samsung did try to get into the worldwide 64 bit CPU market then with Alpha, and could do it now again with AMD. Will it happen? Hardly, in my mind - Uncle Sam m

The wave of hype around server virtualization technology has already receded as solution providers and their customers bury their heads in their SANs and work with mature and maturing technologies from VMware and several competitors. Yet like a Pacific Ocean tsunami, the departure of the wave signals not a falling tide, but the building of a new and larger wave of hype and confusion about how the growing virtualization of server infrastructures impacts the security of the data center. Virtualized servers are in many ways similar to physical servers, with each individual virtual or physical server requiring processor time, memory, I/O, and an operating system to run an application which does not care on which type of server it is found. Yet the difference between having an application run on a dedicated piece of hardware or on one of several virtual servers sharing resources within a physical server is spurring a debate about the best way to protect the virtual world. In one camp are th

DataCore Software today announced that it has made it even easier for server virtualization users to evaluate the cost saving impacts of thin provisioning and iSCSI virtual SANs. DataCore’s free-to-try, downloadable, SANmelody storage virtualization software can now run on and thin provision storage from VMware, XenSource, Virtual Iron and Microsoft virtual machines. “VMware environments and storage networks go hand-in-hand, but the cost to implement a SAN was a major limiting factor until we found and evaluated DataCore,” said Chris Cooper, president, Span the Wan. “The software was easy to install on our existing systems with Ethernet connections. Moreover, SANmelody gave us a lot of flexibility and - most importantly - it worked seamlessly with the VMware set up.“ “The fact that you can download a trial of SANmelody or purchase it without spending thousands of dollars is very important,” stated Marty Zigman, chief technology advisor, Lawyer Links, LLC. “That allows people to take th

Unless ofcourse start considering the security as the "default" option when purchasing Virtualization software for your IT infrastructure. Adoption is getting quicker and don't forget to add security shields as standard installation with every virtualization installation. Lamb says that his post isn't intended to smear VMware specifically, but rather to point out vulnerabilities in virtualization software in general. Virtualization allows enterprises to convert physical hardware, such as servers and desktop PCs, into software, which can then be consolidated onto a single machine, saving energy and hardware costs. But according to Lamb, that consolidation may also turn a business's IT infrastructure into a larger, more unified target for hackers. "Instead of 30 discrete servers, now they're all on one physical machine. You could potentially compromise and own the whole system," he says. In fact, Internet Security Systems released a vulnerability on We

Neil said Windows Server would contain application programming interfaces based on standards developed by the Distributed Management Task Force. The DMTF is an organization that develops and maintains standards for system management of IT environments. Participants in DMTF's efforts in developing standards for plugging management tools into virtualization environments include VMware, XenSource, which Citrix ( CTXS) plans to acquire this year; Dell (Dell), Hewlett-Packard (HP), and others. Microsoft launched this month System Center Virtual Machine Manager 2007, which provides centralized deployment and management of virtual machines, which connect operating systems to the hypervisor or host OS. In addition, System Center enables IT managers to convert VMware offerings to a Microsoft-compatible format. Link

"Virtualisation is a very powerful force in the industry today," the company's senior vice president and general manager of its digital enterprise group told delegates during his keynote speech at the event. "We're now in the process of re-plumbing the entire platform for virtualisation." Looking back at the innovation that has occurred in the last 10 years as the chip giant celebrates the 10th anniversary of the IDF, Gelsinger reiterated the points he made about the potential of virtualisation during VMworld last week, suggesting that this technology will be one of the driving forces over the next decade, alongside the two other key issues of security and manageability. "I presented our vision for virtualisation [at the event] and I looked at some of the key observations around virtualisation technologies. [Historically] we've had a one-to-one relationship between the operating system (OS) and the underlying platform. Virtualisation essentially dis

I am still betting on that "Curve Ball Strategy" where VMware is really getting pretty good at. I am wondering what is keeping Clayton from using VMware to talk about the innovation and continuous disruptive strategies to steer and confuse the competition. Look at it this way, Microsoft felt like it had to make a hypervisor because it was so hot. Everyone talked about it and everyone wanted to hear about it, then suddenly we're talking some weird 3i stuff, so where does that leave Microsoft? Should it make a "super thin viridian"? And then that revenue model story, Microsoft has to take a reactive detour again, first grope in the dark and then come out with some service-less talk at VMworld in 2008? I think what we are are forgetting is that VMware is still offering virtualization and will continue to offer it s the market is barely capitalized, with the VaaS (Virtualization as a Service) strategy, it is merely trying to resolve all the issues that the customers

So it’s not surprising to see the fault tolerant systems vendors turn their attention toward moving their technology into the virtual realm. It’s also not surprising to see them turn toward Xen. The open source Xen hypervisor is getting some attention. Egenera chose Xen as the platform for its virtual environment management tool last fall. And late last year Stratus forged a partnership with XenSource to embed the Xen hypervisor into its fault tolerant technology. And earlier this year, Marathon Technologies announced a deal with XenSource. While Stratus and NEC sell specially designed fault-tolerant x86 systems, Marathon sells fault tolerant software. Marathon’s software uses a virtualisation layer to make two physical servers appear as a single system. Marathon executives say their software, which can run on unmodified Windows servers, reduces the cost and complexity of traditional clustering approaches. Link

I still need to see how cool it is, but given VMware's offerings, it must be! VMware has upped the ante with the release of VMware Site Recovery Manager. According to VMware, “VMware Site Recovery Manager is a pioneering product that uses virtualization to provide end-to-end disaster recovery management and automation across your entire data center.” In a nutshell, Site Recovery Manager uses Virtual Infrastructure 3 in order to help an organization create disaster recovery plans for a data center assuming that the organization has a remote location in which a hot site can be located. Site Recovery Manager takes advantage of your storage solution’s replication capability — a feature found in many (but not all) SAN solutions, both iSCSI and Fibre Channel. Link

This weekend may mark the official end of Summer, but VMware (NYSE:VMW) and EMC Corp. (NYSE:EMC) shareholders are going to have to watch the calendar. The brokerage firm and underwriting quiet period for this super-hot IPO should be ending. This may actually be one of the most impacting events on shares of VMware and on EMC since the IPO, even if it is merely the order of post-IPO transition on the calendar. That being said, the analysts at the underwriting firms will all be able to issue formal research reports and those may start coming very soon.

The DHCP software is used to assign IP addresses to the different virtual machines running within VMware, but IBM researchers discovered that it can be exploited to gain control of the computer. That could be very bad news for someone running a lot of applications on the same VMware box, said Tom Cross, a researcher with IBM's Internet Security Systems group. "By exploiting this vulnerability you get complete control of any of the machines that are running on that virtual environment," he said. IBM's researchers have developed exploit code for three separate flaws in the DHCP software, all of which are now patched, Cross said. In order to attack a system, however, an attacker would first need to gain access to software running within the virtual machine. Typically VMware's DHCP server is not configured to be accessible to systems on other machines. But VMware fixed them alright. They always do it prompty not like Oracle's quaterly bugs, no matter hoe full yer

This technology lets users host desktops inside virtual machines running on centralized servers located in data centers. The virtual desktops are accessed remotely using a traditional PC, a thin client, or a re-purposed computer using a remote display protocol. This type of setup offers high security for sensitive data. Using remote desktop in this way also lets managers set digital rights for VMware environments. The result is device consolidation, lower costs, easier management and more efficient use of servers. Link

This will allow companies to keep a tight security rein on the increasing number of different types of mobile gadgets by making sure that every corporate device adheres to the same consistent security rules, according to the analyst. But the bad news is that such virtualization tools for mobile devices will not be around until 2012--so businesses need to start bringing in policies in the short term, Gartner said. Speaking at the Gartner IT Security Summit here, Monica Basso, research director at Gartner, said more personal devices are being brought into the business space. She said this diversity--and the lack of security on such devices--is putting companies at risk. "Technology over the next five years will allow convergence of (mobile) devices and tools, and virtualization is one of the many enablers to allow this convergence," Basso said. The consumerization of mobile devices "is adding a lot of complexity to IT organizations because there is no one device that will

VMware, in a fit of generosity, has announced it is slashing prices for SMB customers purchasing 3 licenses of VMware ESX. I thought a quick head-to-head comparison with XenEnterprise v4 might help to convince you what a steal this deal really is, and remind you to keep your hands on your wallet. First, the deal offers 3 ESX licenses with Virtual Center thrown in for free. But the Virtual Center version they offer is limited so that it can only connect to 3 ESX servers. And the ESX servers are just ESX servers recycled from their VI3 Starter package, already priced at $1000 per host today, and with a severely hobbled feature set. Of course, when you want to buy your 4th ESX Starter server it will cost you $6,000. That’s $5,000 for a full version of Virtual Center plus another $1,000 for an additional ESX Starter license. And here’s what that ESX starter license won’t offer you: · No SMP support for VMs (1 CPU per VM) · Limited to using 8GB of host memory · Limited to 4 sockets per host

With 3i, instead of executing scripts directly on the Linux-like console, administrators will have access to a remote command line interface (CLI) from a standalone virtual infrastructure (VI) client to perform old ESX commands, said Raghu Raghuram, VMware vice president of platform products. But remote CLI allows administrators to invoke only ESX-specific commands, such as those that start with the "esxcfg" string; Linux-specific facilities are not included. That means that "the commands we use to gather information will remain the same but how we invoke them will have to change," said Alistair Sutherland, director of Taupo Consulting, a VMware integrator in Edinburgh, Scotland. Granted, running scripts in the service console is somewhat of a relic from a previous era, said VMware's Raghuram, even if the practice persists today. "Before VirtualCenter, we had the service console concept, and we used to encourage people to go there," he said. But with t

When recent IPO's in tech stocks reach $20 Billion and $25 Billion in market capitalization rates, it is always interesting to see how this compares to other giants in related sectors. Surprisingly, depending on which source you use, the market capitalization rates are virtually identical for VMware (NYSE:VMW) and Adobe Systems (NASDAQ:ADBE). Here is how the quarterly earnings and growth rates stack up against each other: VMware showed its financial filings of its second quarter on Monday (which were already mostly known), and the results were $296.8 million in revenues (up almost 90% over Q2 2006) and earnings rose over 100% to $34.2 million, or $0.10 on an EPS basis. Adobe's earnings which were not previously known also came out on Monday. The company posted profits of $205 million, or $0.45 EPS on a non-GAAP basis, on revenues of $851.7 million (up 41% from the same period in 2006). The company did already acknowledge that its growth rates would slow in 2008 because i

Qualifying schools provide instructors with technology resources that help them instruct students on software development. VMware also sells its products and services at a discount to higher education and K-12 schools for user in their campus IT infrastructure. This news comes at VMware released most of its VMware Tools as open source. The tools are a suite of guest operating system virtualization components geared to improve Vmware virtual machine performance and management. VMware is aiming to ease Linux integration for its distribution partners with the open source tools by easing porting to new operating systems, increasing user involvement in test and development and fostering innovation. To that end, Linux vendors can now integrate open-source-based VMware Tools--hosted at Sourceforce.net--into future versions of their OSes. Link

Hitachi will continue carving out its own place in the virtualization market with a Xeon-based blade server that includes a built-in hypervisor. In the first quarter of next year, Hitachi America – a subsidiary of the big guy – will ship a Xeon version of the BladeSymphony 1000 system outfitted with homegrown Virtage technology. Virtage stands as Hitachi's firmware-based hypervisor that has been available with the Itanium-based version of BladeSymphony since last November. The pre-loaded hypervisor gives Hitachi a unique attack in the server game with the company claiming performance and security leads over rivals with the technology. Click here to find out more! Built-in hypervisors have suddenly become all the rage. VMware and XenSource have revealed plans to work with OEMs on embedded hypervisors that pop into the flash memory of servers. Hitachi, however, thinks it's creating a much tighter bond between hardware and the hypervisor with its Virtage approach. "All they a

"You can't be a one-trick pony," said Britton Almy, senior consultant in the enterprise systems and storage group with Lewis Center, Ohio-based Sarcom Inc. "You need to understand what's out there and what's driving the market." "Our company is always looking at alternatives, and I actually think it's a good thing with a number of these other vendors coming on, because it's going to get more competitive and that potentially could drive down the costs of virtualization," Almy observed. Even VMware executives said they will work with the competition on certain accounts. "We still work with Citrix; they are going to compete in certain markets, but we've also said whatever they do, if it's a VMware customer and they prefer some Citrix technologies to be deployed together, we are going to continue to work with them," said Brian Byun, VMware's vice president of global partners and solutions.

I think that is what virtualization is making us come to understand. It is bringing all those lonely admins on their lonely islands, together. It is definitely a big challenge for the management as the battle to manage you "own" environment is getting fiercer, al l admins ought to realize one thing: "Stop making an ass of yourselves and start working together, your resume will be pumped up real good. Resisting is worthless!" This was the Epiphany that Chris had, and he says it much better than I can: This is when it occurred to me, that given the general roles and constituent responsibilities of the attendees, most of whom are not dedicated network or security folks, the disconnect between the "Leviathan Force" (the network and network security admins) and the "Sysadmins" (the server/VMM administrators) was little more than the mashup of a classic turf battle and differing security mindsets combined with a lack of network and information secu

Racing to catch up with VMware, Microsoft has delivered Carmine or System Center Virtual Machine Manager (SCVMM), the interface and controls for handling the logical partitions and VMs created by the currently available Virtual Server 2005 R2 and then, well, VMware ESX Server, Xensource and its own Viridian. Carmine can be downloaded from Microsoft's web site now and goes on sale next month as a bundle called System Center Management Suite Enterprise that includes System Center stuff like Configuration Manager 2007, Operations Manager 2007 and Data Protection Manager 2007 for $860 per physical host supporting an unlimited number of VMs. Still cross-platform fucntionality is what we are looking out for.

At the VMworld gathering in San Francisco last week, the buzz centered on the PlateSpin PowerConvert system, which took home a Gold Award for best migration tool. The system lets you stream data, applications and even operating systems between physical and virtual servers, as well as blade infrastructures and image and backup archive systems. It does this by decoupling the workload from network hardware and providing a simple drag-and-drop interface to migrate across multiple environments. There is lot more to virtualization than you can imagine! Read on...

SAS =! SaaS. SAS= serial Attached SCSI ;) LSI Corporation announced it is collaborating with Intel and Microsoft at Intel Developer Forum to demonstrate the scalability, availability and performance enhancements that Serial Attached SCSI (SAS) brings to virtualized environments. LSI will showcase the Windows Server virtualization capabilities of its SAS portfolio at the Independent Hardware Vendor (IHV) Community booth #119, September 18-20, 2007 at the Moscone Center West in San Francisco. In addition, LSI will be displaying its end-to-end SAS solutions and unmatched storage interface breadth at various venues throughout the show, including the LSI booth #229, the Unified Extensible Firmware Interface (UEFI) Community booth #149, and the SCSI Trade Association (STA) booth #324. "With more and more users deploying virtualization technology to capitalize on the operational efficiencies its provides, LSI is working to make sure that our industry-leading SAS portfolio not only meets

One audience member who was keen on the Storage VMotion was Kyle Meyer, a senior systems engineer at Johnson Controls, which has 350 to 400 VMware-powered virtual machines out of a collection of 2,300 total servers. Currently, when the company's EMC Clariion storage systems go off lease, the company has to shut down servers to switch to new storage systems — a task they typically schedule at 3am on Saturday in an effort to minimise disruption. "Nondisruption is the biggest thing," Meyer said. " [Today] we lease Clariion. If we're moving it to somebody else, we've got to shut it down." There are complications to using Storage VMotion, Rosenblum said in an interview after the speech. For one thing, moving a data store takes a long time, even with the "teeny" one and the high-speed network in the demo. For another, a database that's already running full-tilt might not have network capacity to spare for being moved to another storage system. VM

The release of the Windows Server Virtualisation (WSV) pre-beta code, called a community technology preview (CTP), will come at the same time Microsoft ships a new beta release of Windows Server 2008 called “Release Candidate 0.” A release candidate is a final beta before the code is considered finished. Microsoft plans to have at least one more release candidate before the server ships early next year. Microsoft made the announcement at VMWorld, the annual conference of its biggest virtualisation rival VMware. Microsoft said the CTP will not include all the features that are planned for the final version. Read the rest.

Good luck to Sun fellas! Virginia also ties together Sun's various storage virtualization efforts, including its homegrown - please ignore, NetApp employees - ZFS file system and the recently acquired Lustre file system. Then, there's a network virtualization element as well that comes from Sun's Crossbow technology for slicing up NICs to manage bandwidth between applications. As far as we understand it, all of these technologies will soon be controlled in one place by a revamped version of Sun's N1 management software. As Schwartz mentioned last week, Sun's virtualization play will now cover Windows in addition to Solaris and Linux. If past performances are any indication, Sun will announce this broad virtualization management project soon but actually deliver it much, much later. (We're willing to be proved wrong here.) Should Sun actually have all these pieces lined up, it stands to show off one of the most complete virtualization architectures on the market.

Rosenblum also laid out a blueprint for some of the issues he'd like to see the AMD and Intel tackle. He said that VMware didn't always get what it wanted from the processor makers and that VMware needed more visibility into how virtual machines use the processor cache in order to provide better quality of service. In particular, he referred to the problem of a VM demanding huge amounts of processor resource that affected other processor cores. He said: "We've made great steps, but if you have a 10-gig NIC with tiny packets coming, it can consume a whole CPU just looking at each of them, so it's really difficult trying to match line rate."

SteelEye Technology , a leading provider of VMWare protection solutions including data replication and application monitoring for business continuity and disaster recovery on Linux and Windows, announced today at VMworld 2007 that it has joined the VMware Technology Alliance Partner (TAP) program. VMware (NYSE: VMW), the global leader in virtual infrastructure software for industry-standard systems, provides the Technology Alliance Partner program to enable technology vendors to support and integrate with the VMware infrastructure and deliver solutions to our joint customers.

He plans to defend it soon. Its actually called : Performance Virtualization and QoS in Shared Storage Systems This dissertation targets the problem of performance virtualization in shared storage systems. This is motivated by growing trends towards storage consolidation. The goal is to provide performance guarantees to an application irrespective of the behavior of other concurrent workloads. In doing so, we propose QoS scheduling mechanisms for both centrally shared storage systems and distributed storage systems such as FAB and IceCube. QoS and efficiency are two strongly opposing forces when it comes to sharing of I/O devices, and it is a challenge to achieve both simultaneously. Link

The Pillar Axiom platform is architected to help users consolidate their storage resources, while simplifying management to reduce the cost to acquire, administer, and maintain midrange storage systems. Aligned tightly with VMware’s ability to maximize efficiency for the server environment, Pillar integrates with VMware Infrastructure 3 to enable users to benefit from increased Quality of Service (QoS) at the storage layer. This allows for improved storage resource allocation, a highly available architecture and enhanced interoperability with the current infrastructure, which ensures that customers can drive maximum storage efficiency in a variety of application environments “The strength of the Pillar Axiom lies in its unique ability to separate and prioritize the performance requirements for each application or database on each array, and allow the system to expand capacity or performance in line with the user’s requirements. This is a key enabling technology in making the Pillar Axi

Somewhere near the top of the list of activities that storage people like doing least is data migration. Slow, time-consuming, and often scheduled at convenient times such as 3 a.m. Sunday morning, it has to rank up there with tasks like disaster recovery testing and SAN reconfiguration. To make matters worse, the process often seems to be a prime candidate for Murphy's Law, often exceeding scheduled windows or needing to be rolled back and rescheduled due to unforeseen problems. The methods used to perform migrations can vary considerably depending on what, where and how much data is being migrated, and in recent years, the number of technology options has increased significantly. In addition to traditional approaches (for example, host-based migration tools and like-to-like storage-array-based replication), a growing trend is toward applying virtualization technologies for data-migration purposes. Virtualization appliances than sit in the SAN or LAN are one category of the new br

The VMware Virtual Desktop Infrastructure (VDI) solution is a result of the collaboration between vendors and VMware to make the Thin Client OS aware of key VMware VDI technologies. The end result, Thin OS-VDI Edition, is designed to enhance the user experience and functionality. Arun Rao, Business Manager – Client Virtualization, Personal Systems Group, Hewlett-Packard India says, “Delivering all the qualities associated with VMware VDI in a single ‘push the power button to work’ device, the solution incorporates the new Thin OS-VDI edition software and is delivered on the thin client appliance.” According to a NEC official the major driving factors VDI in thin clients are security, manageability, reliability, availability and, last but not the least, a reduction in overall TCO. With NEC Sigma System Centre (SSC) featuring system provisioning and deployment manager, it is easy to manage the IT infrastructure more efficiently. Enterprise Desktop Virt

QLogic Corp. , a leader in networking for storage and high performance computing, today announced it is first to demonstrate VMware virtual machine migration using QLogic® virtual HBA technology. Live migrations allow IT managers to take down a working server, upgrade the operating system or apply patches, and then bring it back up again while users continue to access applications on the server. The demonstration at VMworld is part of a collaboration between QLogic, VMware and its Community Source program to complement server virtualization software with hardware-assisted virtualization. The hardware-assist virtualization technology inside QLogic SANblade® HBAs eliminates the need for ESX administrators to reconfigure SAN functions after live virtual machine migrations. “Customers are now consolidating more VMs onto a single, physical server,” said Greg Schulz, founder and senior analyst, The StorageIO Group. “NPIV technology helps link worldwide port names to individual virtual machin

Just like Applications , as I mentioned in the previous post, security will also change dramatically. Changes can be Painful for many Security Solutions In production environments effortless movement and changes of VM states (snapshot, revert, online, offline, VMotion, etc) can generate extreme operational challenges for critical security activities like vulnerability scanning, patching and security. Vulnerability scans, a critical tool for tracking software vulnerabilities, can become obsolete in seconds. Bottom line: The constant change enabled by virtualization can place dynamic demands on the most commonly deployed static security solutions, in even small virtualized production infrastructures. All the tricks, flips and tools that make software more nimble and powerful will not matter unless the production infrastructure can be effectively secured from attack. Yet many of the leading network security vendors have been caught flat-footed by virtualization. Some are even trying to c

we never ought to forget about applications, yes, its the applications that have to be addressed, no matter which technology you use. I will be talking about the importance of applications, which amidst all the virtualization craze, may taker a bit of a back seat. As Rosenblum shows with VMotion, the application gets a "warm HA' blanket as it moves to another server: Rosenblum started a server on stage that was running the equivalent of 50 users pounding on Microsoft Outlook. The server's ongoing activity was being mirrored on a second server, which was receiving a live stream of events as they were entered into the log of the virtual machine on the first server. As Rosenblum unplugged the first server, VMware's management software, Virtual Infrastructure 3, detected a failure and shifted handling the users to the secondary server. Since the secondary server was already receiving a stream of log events, it could pick up at the precise point where the other had left
