A 25 Gbit/s RoCE interface module connects a storage device to an application server or forwards data within a storage device. The optical module rate must be consistent with that on the interface module label. The RDMA over Converged Ethernet (RoCE) IP developed by Microchip Technology is a high-performance, low-latency network interface solution designed to enhance data center and cloud computing environments. RoCE, which stands for RDMA over Converged Ethernet, enables Remote Direct Memory Access. Remote direct memory access (RDMA) enables server-to-server data movement directly between application memory without CPU involvement. Using any of the following IBM RoCE Express adapters, RDMA technology is available on Ethernet. RDMA technology provides the capability to allow hosts to logically share memory.
