Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. To check for operating system and partition requirements, see one of the following links:
v The latest version of enabling libraries and utilities can be downloaded from Fix Central
v IBM Power Systems Prerequisites (
v IBM SSIC (System Storage Interoperation Center)(
v The latest version of the device driver or the IBM Power RAID adapter utilities (iprutils) can be
downloaded from the IBM Service and Productivity Tools website (

PCIe3 2-port 10 GbE NIC & RoCE SFP+ Copper Adapter (FC EC37 and EC38 - RP
EL3X and EL53; CCIN 57BC)
Learn about the specifications and operating system requirements for the feature code (FC) EC37 (RP
EL3X) and EC38 (RP EL53) adapters.
The FC EC37 (RP EL3X) and EC38 (RP EL53) are the same adapter. FC EC37 (RP EL3X) is a low-profile
adapter and FC EC38 (RP EL53) is a full-height adapter.
Note: FC EL3X is only supported on 9008-22L.
The PCIe3 2-Port 10 GbE NIC & RoCE SFP+ 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 FCs EN01, EN02
or EN03. A copper transceiver is included with these cables. See "Cables" on page 55 for details. Each 10
Gb port provides Ethernet connectivity with a nominal data rate of 10 Gbps (gigabits per second).
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.
v The adapter supports the following standards for the different ports and functions:
– AIX NIM and Linux Network Install are supported
– IBTA RoCE v2 support
– IEEE 802.3ae in the 10 GbE ports
– 802.3ab in the 1 GbE ports
– Ether II and IEEE 802.3 for encapsulated frames
– 802.1p for setting up priority levels in tagged VLAN frames
– 802.1Q for VLAN tagging
