PCIe3 LP 2-Port 10 GbE NIC and RoCE SFP+ Copper Adapter (FC EL3X; CCIN
Learn about the specifications and operating system requirements for the feature code (FC) EL3X adapter.
The PCIe3 2-Port 10 GbE NIC and RoCE SR adapter is a PCIe generation-3 (PCIe3), full-height, dual port,
10 Gigabit Ethernet (GbE) adapter with a PCIe 3.0 host bus interface. The adapter provides two 10 Gb
SFP+ ports for copper twinax cabling. These cables also include copper transceivers. The adapter is a
converged network adapter supporting both NIC and IBTA RoCE standard. RoCE is Remote Direct
Memory Access (RDMA) over Converged Ethernet. Using RoCE, the adapter can support significantly
greater bandwidth with low latency and minimize CPU overhead by more efficiently using memory
access. This offloads the CPU from I/O networking tasks, improving performance and scalability.
Active Copper twinax cables up to 5 meter in length are supported such as provided by feature codes
EN01, EN02 or EN03. A copper transceiver is included with these cables. See "Cables" on page 115 for
details. Each 10 Gb port provides Ethernet connectivity with a nominal data rate of 10 Gbps (gigabits per
second). Figure 51 on page 114 shows the FC EL3X adapter.
The adapter provides the following features:
v The adapter is a PCIe3 NIC network convergence adapter.
v The adapter supports RoCE and NIC functions but not concurrently on same adapter.
