Samsung Unveils CXL Memory Module Box: Up to 16 TB at 60 GB/s

Composable disaggregated data center infrastructure promises to change the way data centers are built for modern workloads. However, to fully realize the potential of new technologies like CXL, the industry needs brand new hardware. Recently, Samsung introduced its CXL Memory Module Box (CMM-B), a device that can hold up to eight CXL Memory Module – DRAM (CMM-D) devices and connected memory using the PCIe/CXL interface. can add a substantial amount of

Samsung's CXL Memory Module Box (CMM-B) The device is the first of its kind to accommodate eight 2 TB E3.S CMM-D memory modules and add up to 16 TB of memory for up to three modern servers with the appropriate connectors. As for performance, the box can offer up to 60 GB/s bandwidth (which is in line with what the PCIe 5.0 x16 interface offers) and 596 ns latency.

From a pure performance perspective, a CXL memory module—box is slower than a dual-channel DDR5-4800 memory subsystem. Even so, the unit is still quite fast compared to high-end SSDs. At the same time, it provides very decent capacity, which is often just what the doctor ordered for many applications.

Samsung CMM-B is compatible with CXL 1.1 and CXL 2.0 protocols. It consists of a rack-scale memory bank (CMM-B), several application hosts, Samsung Cognos management console software, and a top-of-rack (ToR) switch. The device was developed in close collaboration with Supermicro, so expect the server maker to be the first to offer the product.

Samsung's CXL Memory Module – Box is designed for applications that require a lot of memory, such as AI, data analytics, and in-memory databases, though not all the time. CMM-B allows a system to dynamically allocate the necessary memory when it needs that memory and then share the DRAM with other machines. As a result, operators of data centers can save money on expensive memory acquisitions (16 TB of memory is expensive), reduce power consumption, and add flexibility to their setups.
