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. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/fixcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
• IBM SSIC (System Storage Interoperation Center) (http://www-03.ibm.com/systems/support/storage/
ssic/interoperability.wss).
• The latest version of the device driver or IBM Power RAID adapter utilities (iprutils) can be downloaded
from the IBM Service and Productivity Tools website (http://www14.software.ibm.com/webapp/
set2/sas/f/lopdiags/home.html).
• For support details, see the Linux Alert website (http://www14.software.ibm.com/webapp/set2/sas/f/

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.
