Unformatted text preview: ges of implementing our consolidation strategy. Preliminary results have validated our assessment; all indications are but increase the memory required per VM. We expect that this would not materially change overall virtualization host memory requirements. 9 White Paper Memory Sizing for Server Virtualization Conclusion Intel IT has standardized on 16 GB of memory for dual-socket virtualization host servers, based on extensive analysis of maximum physical memory consumption on more than 3,000 servers running non-virtualized workloads. We found that approximately half of these servers consume 1 GB of memory or less. For workloads of this size, our experience to date indicates that we can achieve consolidation ratios of up to 15-20 to 1 using low-cost dual-socket virtualization hosts based on quad-core processors. Our analysis indicates the importance of host memory based on measurements of carefully monitoring memory consumption on actual memory consumption, we believe we can the systems to be virtualized in order to size maximize utilization of virtualization host server virtualization host memory appropriately. Our memory and avoid paying for unused memory monitoring showed that for many servers, actual and associated data center power and cooling. memory use is modest.
