The Lenovo X6 servers support up to 96 DIMMs or 6 TB of memory in an x3850 X6 four-socket configuration and 192 DIMMs or 12 TB of memory in an x3950 X6 eight-socket configuration. By comparison, almost all two-socket servers max out at 1.5 TB of memory. The large X6 memory capabilities allow clients to support memory-intensive workloads, implement large virtual machines or run sizeable in-memory databases without compromise.

But how do you make sure you are optimizing your memory performance? The support of RDIMM and LRDIMM memory can be optimized for performance and large memory capacity requirements. Although every application has unique characteristics, adhering to best practices produces a system that is configured for optimal memory performance.

Optimizing memory performance can offer the following benefits.

  • Improve server performance
  • Reduce power consumption
  • Improve server consolidation and virtual machine performance
  • Help delay hardware refresh expenses

A new Lenovo Press document titled Optimizing Memory Performance of Lenovo Servers Based on Intel Xeon E7 v3 Processors is now available to help you optimize your memory performance. This paper covers memory latency, bandwidth and application performance. In addition, the paper describes performance issues that are related to CPU frequency, memory speed and population of memory DIMMs. Finally, the paper examines optimal memory configurations and best practices for the Lenovo X6 platforms.

In this paper, you can learn about:

1) Lenovo X6 system architecture and how it supports memory

2) Memory performance

  • Measurement configuration
  • Memory modes
