NVMe expansion enclosure

The NVMe expansion enclosure includes slots for 24 2.5-inch NVMe SSD drives. It uses an NVMe interface for communication between the nodes and the NVMe expansion enclosure. The NVMe expansion enclosure uses the RDMA over Converged Ethernet (RoCE) network protocol to enable Remote Direct Memory Access (RDMA). This allows the system to encapsulate RDMA packets over Ethernet, which results in low latency, lower CPU usage, and higher bandwidth. Because PowerStore utilizes an NVMe over Fabric (NVMe/OF) standard, the NVMe expansion enclosure delivers an end-to-end NVMe solution.

NOTE:The NVMe expansion enclosure is not supported on systems that include SAS expansion enclosures.
NOTE: The NVMe expansion enclosure requires that the base enclosure includes the v2 embedded module and a 100 GbE 2-port card.
NOTE:The NVMe expansion enclosure does not support NVMe SCM drives and is not supported with SCM-only base enclosures.
