Avastu Blog: Sustainable Global Clouds

(Aliso Viejo, CA — October 1, 2008)— 3Tera®, Inc., the leading innovator of cloud computing technology and utility computing services, announces beta availability of AppLogic™ 2.4 which includes support for virtual appliances running Microsoft® Windows Server™ incorporated in all infrastructure components necessary to run Web applications including storage, networking and load balancing. The new functionality is available immediately both as a service in the cloud and as private clouds in enterprise datacenters. For the first time, a cloud computing platform enables virtual datacenters that exceed the capabilities of traditional datacenters in commercial enterprise environments. Complete Cloud Computing Solution Adding Windows to AppLogic’s existing support of Linux, Sun’s Open Solaris™ and Solaris™ 10 follows 3Tera’s Cloudware™ architecture for open cloud computing, announced earlier this year. Users of AppLogic can now utilize the most popular datacenter operating systems in their ap...

We have been building and even doing our performance/benchmarks tests on the ESX 3.x and Oracle RAC. And Sun folks too want to demo their cool software on ESX. However, VMware ESX has a feature called Raw Device Mapping (RDM), which allows the guest operating systems to have direct access to the devices, bypassing the VMware layer. More information on RDM can be found in VMware documentation. The following documents could be starting points: http://www.vmware.com/pdf/vi3_301_201_intro_vi.pdf http://www.vmware.com/pdf/vi3_301_201_san_cfg.pdf RDM works with either Fibre Channel or iSCSI only. In the setup here, a SAN storage box connected through Fibre Channel was used for mapping LUNS to the physical hosts. These LUNS could then be mapped onto the VMware guests using RDM. SCSI reservations have been found to be working fine with RDM (both SCSI-2 Reserve/Release and SCSI-3). These RDM devices could therefore be used as shared devices between the cluster nodes. However, of course they can...

This blogger tests SolarisExpress Installation on Virtual PC 2007. So installed Virtual PC 2007 there, create a new virtual machine. I decided that 256MB memory (later I realized that this is not enough) and 8GB Virtual HDD. The installation medium is DVD and I’m using host DVD drive for installation. I started the virtual machine, booting from DVD. The grub menu is loaded and I choose the default option (not from serial console). Then the kernel is loaded and actually it can get to Installation options. I choose the default GUI installation, but later it failed and told me that GUI installatation requires min 400MB memory (whoa other OSes doesn’t required this much for GUI installation). Check it out .
