As much as 16 TB at 60 GB/s

Composable disaggregated knowledge heart infrastructure guarantees to alter the best way knowledge facilities for contemporary workloads are constructed. Nevertheless, to completely understand the potential of recent applied sciences, akin to CXL, the trade wants brand-new {hardware}. Lately, Samsung launched its CXL Reminiscence Module Field (CMM-B), a tool that may home as much as eight CXL Reminiscence Module – DRAM (CMM-D) units and add loads of reminiscence related utilizing a PCIe/CXL interface.

Samsung’s CXL Reminiscence Module Field (CMM-B) is the primary gadget of this sort to accommodate as much as eight 2 TB E3.S CMM-D reminiscence modules and add as much as 16 TB of reminiscence to as much as three fashionable servers with applicable connectors. So far as efficiency is anxious, the field can provide as much as 60 GB/s of bandwidth (which aligns with what a PCIe 5.0 x16 interface presents) and 596 ns latency. 

From a pure efficiency viewpoint, one CXL Reminiscence Module—Field is slower than a dual-channel DDR5-4800 reminiscence subsystem. But, the unit remains to be significantly quicker than even superior SSDs. On the identical time, it gives very first rate capability, which is commonly simply what the physician ordered for a lot of functions.

The Samsung CMM-B is appropriate with the CXL 1.1 and CXL 2.0 protocols. It consists of a rack-scale reminiscence financial institution (CMM-B), a number of utility hosts, Samsung Cognos administration console software program, and a top-of-rack (ToR) swap. The gadget was developed in shut collaboration with Supermicro, so count on this server maker to supply the product first.

Samsung’s CXL Reminiscence Module – Field is designed for functions that want loads of reminiscence, akin to AI, knowledge analytics, and in-memory databases, albeit not always. CMM-B permits the dynamic allocation of obligatory reminiscence to a system when it wants this reminiscence after which makes use of DRAM with different machines. Consequently, operators of datacenters can spend cash on procuring costly reminiscence (16 TB of reminiscence prices so much), cut back energy consumption, and add flexibility to their setups.
