An ULLtraDIMM is flash memory interfaced to a memory DIMM connected to a computer's main CPU-Memory bus instead of the PCIe bus, which avoids the latter's longer latency before data can be sent to or read from the flash. It’s based on Diablo Technologies’ Memory Channel Storage technology, which SanDisk’s SMART acquisition used to connect flash and DIMMs.

SuperMicro tested 200GB and 400GB ULLtraDIMM devices, and Wally Liaw, Sales SVP at Supermicro, said: “Supermicro … delivers the lowest latency server and storage platforms on the market with SanDisk’s ULLtraDIMM technology.”

ULLtraDIMM SSDs are expected to begin shipping in Supermicro’s SuperServer and SuperStorage platforms in the fourth quarter of the year. ®
