Optimizing for Virtualization, Part 2 – AnandTech
By consolidating previously separate storage systems into a single array, servicing multiple VM’s, we notice a change in access patterns. Because of queueing systems on all levels (guest, ESX and the array itself), what are actually supposed to be sequential reads coming from a single system get interleaved with the reads of other VM’s, resulting in a random access pattern. Keep this in mind when you notice a drop in otherwise solidly performing sequential read operations.
How Raytheon’s IT Department Helps Meet Green Goals – Computerworld
What They Did: Raytheon virtualized or decommissioned 1,300 servers and established common database services to reduce system acquisition, power and cooling costs. IT encouraged Raytheon’s businesses to use shared resources by offering a discount that trumped dedicated resources. Server virtualization enabled Raytheon to avoid building a major data center despite a 25 percent growth in capacity demand. Green IT projects produced more than $11 million of savings in 2008.

L.L. Bean Data Center Earns LEED Silver – Web Host Industry Review
From its initial a conceptual design, the idGroup’s design evolved to suit L.L.Bean, meeting the criteria of both LEED Silver and the American Society of Heating Air Conditioning Engineering (www.ashrae.org), adding some local touches along the way. Along with minimizing environmental disturbance and recycling half of all construction waste, materials were sourced locally, including the structure’s distinctive New England-style shingles, which were made from wood harvested within a 500-mile radius, using sustainable forestry practices.
