MemCon: MemVerge to Demo How CXL Memory Expansion Will Close Gap Between CPU and Memory Performance

Adding CXL memory boosted transactions/second by 15%, with addition of Memory Machine software boosting performance another 12%

MemVerge, Inc. is attending MemCon to demonstrate the capacity and performance benefits of Compute Express Link (CXL) memory.

The demo features a server running an OLTP benchmark, with Memory Machine software from the company that provides tiering for system DIMM and E3.S CXL memory expansion from Micron.

Adding CXL memory boosted transactions per second by 15%, with the addition of Memory Machine software boosting performance another 12%.(1) The results highlight the potential to close the gap between CPU and memory performance due to memory capacity and performance per core limitations – known as the ‘memory wall’ problem – by supplementing DIMM bandwidth and capacity with CXL expansion memory.

CXL allows capacity and bandwidth expansion to address the memory wall. It also adds a new paradigm to Memory Tiering,” says Raj Narasimhan, SVP and GM, compute and networking business unit, Micron Technology, Inc. “Our collaborative demo with MemVerge at this week’s MemCon event showcases that the capacity and bandwidth unlocked by CXL translates to significantly better application performance.

Additionally, CXL memory expansion will improve workload performance while keeping costs down and creating new data center system architectures through the application of memory and storage hierarchies. These results will enable greater flexibility in data center design and use to support data-intensive workloads.

According to Charles Fan, CEO and co-founder, MemVerge, application transparency will be crucial to the success of CXL: “Our configuration running at MemCon demonstrates the ability of the CXL ecosystem to deliver tiered memory systems that can be deployed without modification to apps.”

(1) Improved performance results were obtained with a CXL-enabled 4th gen AMD EPYC processor. The test system also used Micron 256GB CXL memory modules that ran at Gen5 speed in conjunction with the MemVerge Memory Machine memory tiering software solution on the Linux OS.
