NVMe-oF Adapter Technology – VDS2249R

High Performance Enterprise Class Storage Using NVMe™ over Fabrics Technology

The Viking Enterprise Solutions (VES) VDS2249R Fabric Enclosure offers twenty-four 2.5-inch U.2 (SFF8639) NVMe™ SSDs with up to six NVMe-oF bridge add-in cards with 100 GbE QSFP28 network ports.

The enclosure provides access to the high performance NVMe-oF drives over the network with virtually no latency or performance penalty.

Two fabric modules are included with the enclosure. Each fabric module has a PCIe v3.0 switch network and three PCIe add-in cards slots that are compatible with a wide range of Ethernet fabric adapter cards (half-height, half-length, up 70W of power).

The solution utilizes third-party add-in cards and offers six 100 GbE QSFP28 network links for NVMe-oF™ access to the drives. All of the NVMe-oF target protocol occurs in hardware without the need of a host CPU. This provides a combination of incredible performance at over 15M IOPs, and extremely low total latency of less than 16μs. This total includes both fabric latency (<8μs) and NVMe-oF drive latency).
