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:

PCIe3 2-port 25/10 Gb NIC & RoCE SFP28 Adapter (FC EC2T and EC2U; CCIN
58FB)
Learn about the specifications and operating system requirements for feature code (FC) EC2T and 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.
