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.
