Big Memory Servers

Memory Expansion in High Performance Servers

Compute Express Link (CXL) is a high-speed, low-latency interconnect designed to enhance communication between CPUs, memory, and accelerators such as GPUs and FPGAs. By enabling memory expansion and device coherency, CXL improves performance and efficiency in modern data centers.

Scaling memory capacity beyond traditional DIMM limitations—CXL technology is ideal for memory-bound workloads such as in-memory databases, AI/ML, and large-scale simulations. CXL 2.0 offers a flexible, cost-effective path to higher performance and capacity without overhauling your existing infrastructure.
