CXA-4F1W

AIC (Add In Card)

SMART’s CXA-4F1W is a 4-DIMM AIC, a Type 3 PCIe Gen5 Add-In Card (AIC) utilizing the CXL™ standard consisting of four DDR5 RDIMMs mounted on a Full Height, Half Length PCIe form factor module. It uses one x16 CXL controller to implement a single x16 CXL port capable of a total bandwidth of
64GB/s.

Each RDIMM socket supports up to 128GB RDIMMs for a maximum memory capacity of 512GB. The CXL Controllers implement “Reliability, Availability, and Serviceability” (RAS) features, advanced analytics, as well as enhanced security features with in-band or side band (SMBus) monitoring capability.

SMART develops CXL Type 3 (CXL.mem) memory products to address the industry’s need for more memory per processor core. The CXL interconnect specification allows for a significant expansion of memory form factor options in PCIe or EDSFF form factors.
