PMem can reduce memory costs in two socket systems with more than 512 GB of memory, enabling greater consolidation ratios and increasing infrastructure utilization. By increasing utilization, more VMs can run on each host, which may reduce the number of hosts that are needed to address workload demands.
Because PMem enables larger memory systems that allow greater VM consolidation, using fewer systems, software licensing fees, and management complexity can be reduced. These benefits result in increased operational efficiency and reduced TCO.
Systems with larger memory sizes can reduce the number of disk IOs needed, improving overall performance.
As this paper has demonstrated, memory cost savings can be as high as 45 percent if the DRAM to PMem ratio is kept at 1:4, according to the configuration recommendations and best practices guidelines provided.
