Some interesting tidbits I took away were:
- Implementing our virtualization strategy required investments across all aspects of the data center, including server, storage and network
- Intel IT averages 10:1 consolidation for servers and 15:1 for storage with opportunity for even higher density moving forward
- Appropriate server sizing depends on a variety of many variables including risk tolerance, flexibility, cost and financial goals
- Break even financial ROI occured at ratios of less than 4VM / server
The bottom line conclusion of the implementing virtualization white paper is that Intel IT will accelerate our virtualization efforts to more environments and at a faster pace in 2010 continuing to utilize the latest generation of 2S and 4S Intel Xeon based servers.
There is a bit more at the original article. However, I think these results are quite stunning. Pumping up utilization by installing as few as 4 virtual machines greatly increases the value of a server to a business. Virtualization has shown tremendous cost savings and ROI. Terrific, hard numbers to take to management to justify the investment in virtualization and hardware systems optimized for doing so.
