IBM PCIe3 2-port 10 Gb NIC & RoCE SR/Cu adapter
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.

- Cables
- For 10 GbE, IBM® offers Direct Attach Copper (DAC) cables up to 5 M. SFP based transceivers are included on each end of these cables. For more information about adapter cabling, see the Cable and Transceiver information.
- Transceivers
- IBM® qualifies and supports SFP+ optical transceiver (FC EB46) to install into the adapter. Customers can also use their own optical cabling and SFP+ optical transceiver for the other end. The 10 Gb optical transceiver is capable up to 300 M through the OM3 cable or 82 M through OM2 cable. Either one or both of the adapter’s two SFP+ ports can be populated.
Cable and Transceiver information
- OM3 or OM4: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
- OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
- OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best results, OM2 cables must not be connected to OM3 or OM4 cables. However, if an OM2 cable is connected to an OM3 or OM4 cable, the characteristics of the OM2 cable apply to the entire length of the cables. The following table shows the supported distances for the different fiber optic cable types at different link speeds.
Rate | Cable type and distance | ||
|---|---|---|---|
| 10 Gb/s | OM1 | OM2 | OM3 |
| 0.5 m to 33 m (1.64 ft to 108.26 ft) | 0.5 m to 82 m (1.64 ft to 269.02 ft) | 0.5 meters to 300 meters (1.64 ft to 984.25 ft) | |
