Recent VMware Communities forum discussions have brought Forensics to the fore once again. Even so it has made me think of using virtualization tools to do preliminary analysis -- something that could tell you if the time and effort of full acquisition is required.
Disk deduplication (Dedupe) is a forensically untried solution to the need for more disk space within data centers. Untried does not mean unsound, but until the forensic science can catch up with the technology there may be issues.
How to fix the cryptic VMware HA failed with error messages. This is a caustic error that actually has no real meaning other than to say VMware HA could not start, but not actually why!
Many people are confused about VMware EVC and how to configure this on their systems. When most people go to configure EVC they attempt to turn it on and get this hardware does not support EVC. Which is untrue for 98% of the attempts. There is more to enabling EVC than many realize.
VMware HA was busted when VMware ESX 3.5 Update 2 was applied. VMware HA would fail to fire when a node was down, fail to evacuate VMs when entering maintenance mode, and fail to start VMs, with a not enough resources error, if the second node was down. This all applied to the SMB two node cluster world. With VMware Virtual Center 2.5.0 Update 3 and the 10/3/08 patches for ESX this is now fixed.
In discussions with backup companies about digital forensics I discovered some useful items. Specifically that full VMDK backups may be forensically sound and that there is a way to dump the memory of a VM before you kill it like pulling the plug.
Sidekick: The Good News & the Bad News Either way you look at it Microsoft Data Center management did not follow standards or best practices in this failure. In which case it makes me wonder more about the outsourcing of corporate data much less personal data.

AISO founders envisioned a Web hosting company that was environmentally friendly. While the company employed energy-efficient innovations like solar panels, its infrastructure produced unacceptable power and cooling requirements. Find out how AISO leveraged AMD technology to overcome their challenge in this case study white paper.
In this whitepaper, Scalar explores the opportunity to change the landscape with respect to mission critical databases
built around Oracle. Leveraging technologies such as Linux, high-end commodity processing power and Oracle RAC
technology to architect, design, build and maintain database infrastructure that delivers maximum availability, reliability
and performance at a fraction of traditional cost.
On a typical day, weather.com, the Web site for The Weather Channel in Atlanta, serves up between 15 million and 20 million page views. But in September 2004, when back-to-back hurricanes ransacked Florida, the peak traffic on one day more than tripled: over 70 million page views by more than 7 million unique visitors. Read the full success story now.
