SMART’s CXA-8F2W is an 8-DIMM AIC utilizing the CXL™ standard. It’s a Type 3 PCIe Gen5 Add-In Card (AIC) consisting of eight DDR5 RDIMMs mounted on a Full Height, Half Length PCIe form factor module. It uses two x16 CXL controllers to implement two x8 CXL ports capable of a total bandwidth of 64GB/s.
Each RDIMM socket supports up to 128GB RDIMMs for a maximum memory capacity of 1TB. 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 Type 3 (CXL.mem) memory products utilizing the CXL standard 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.
