CXL (Compute Express Link) Explained: Unifying Memory Pools Across Enterprise Clusters

Rigid server-bound memory configurations result in up to 50% stranded DRAM capacity, driving up infrastructure CapEx and throttling AI and high-performance computing workloads.
Compute Express Link (CXL) introduces low-latency, cache-coherent interconnects that disaggregate memory resources into dynamically shareable pools across heterogeneous server clusters.
Infrastructure teams are leveraging CXL 2.0/3.0 switching to scale high-bandwidth AI training nodes and large-scale in-memory database clusters without proportional hardware over-provisioning.
Designed for CTOs, CIOs, cloud infrastructure architects, and data center engineering leaders modernizing hyperscale computing clusters.
