PCIe3 2-port 10 Gb NIC & RoCE SR/Cu adapter (FC EC2R and EC2S; CCIN 58FA)
Learn about the specifications and operating system requirements for feature code (FC) EC2R and EC2S
adapters.
Overview
FC EC2R and EC2S are both the same adapter with different feature codes. FC EC2R is a low-profile
adapter and FC EC2S is a full-height adapter.
The PCIe3 2-port 10 Gb NIC & RoCE SR/Cu Adapter is a PCI Express (PCIe) generation 3 (Gen3) x8
adapter. The adapter provides two 10 Gb SFP+ ports and supports both the Ethernet network interface
controller (NIC) function and RDMA over Converged Ethernet (RoCE). The adapter can support
significantly greater bandwidth with low latency using RoCe. It also minimizes CPU overhead by more
efficiently using memory access. This offloads the CPU from I/O networking tasks, improving performance
and scalability.
