Storage Virtualization rethinks Virtualization

Hitachi added another chapter to its virtualization story by extending the thin provisioning feature of its high-end Universal Storage Platform V to externally attached storage systems from other vendors.

HDS also added support for SATA drives and boosted USP V performance to more than 4 million IOPS.

"At some point, we almost stop counting," said HDS chief scientist Claus Mikkelsen.

HDS, which has shipped more than 7,300 virtual storage controllers to date, said Hitachi Dynamic Provisioning software lets customers allocate virtual disk storage based on their anticipated future requirements without dedicating physical disk storage up front. If the need for additional physical disk arises, capacity can be purchased at a later time without disruption. Only the capacity that is required to hold the actual data is provisioned and replicated, requiring fewer physical disks and resulting in a lower carbon footprint.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
