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.
