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 25/10 Gb NIC & RoCE SFP28 adapter (FC EC2T and FC EC2U; CCIN 58FB)
Learn about the specifications and operating system requirements for feature code (FC) EC2T and FC
EC2U adapters.
Overview
FC EC2T and EC2U are both the same adapter with different feature codes. FC EC2T is a low-profile
adapter, and FC EC2U is a full-height adapter.
The PCIe3 2-PORT 25/10 Gb NIC & RoCE SFP28 Adapter (FC EC2T and EC2U) is a PCI Express (PCIe)
generation 3 (Gen3) x8 adapter. The adapter provides two 25 Gb SFP28 ports. The adapter supports both
the Ethernet network interface controller (NIC) function and RDMA over Converged Ethernet (RoCE).
Using RoCE, the adapter can support significantly greater bandwidth with low latency. It also minimizes
CPU overhead by more efficiently using memory access. This offloads the CPU from I/O networking tasks,
improving performance and scalability.
