Pcie4 2-Port 100 Gbe Roce X16 Adapter (Fc Ec66 And Ec67; Ccin 2Cf3) - IBM Power System Series Manual

Thermal requirement
If you have an 8335-GTG, 8335-GTH, or 8335-GTX system, you might be required to set the thermal
mode of the system to a setting other than the default setting, depending on your system, adapter,
and cable type. For details, see Determining and setting the thermal mode for an 8335-GTG, 8335-
GTH, or 8335-GTX system.

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://

PCIe4 2-port 100 GbE RoCE x16 adapter (FC EC66 and EC67; CCIN 2CF3)

Learn about the specifications and operating system requirements for feature code (FC) EC66 and EC67
adapters.
Overview
FC EC66 is a full-height adapter and FC EC67 is a low-profile adapter.
The PCIe4 2-port 100GbE RoCE Adapter is a PCI Express (PCIe) generation 4 (Gen4) x16 adapter. The
adapter provides two 100GbE QSFP28 ports. The PCIe4 2-port 100GbE RoCE Adapter supports both NIC
(Network Interface Controller) and IBTA RoCE standards. RoCE is Remote Direct Memory Access (RDMA)
over Converged Ethernet. Using RoCE, the adapter can support significantly greater bandwidth with low
latency. It also minimizes the CPU overhead by more efficiently using memory access. This offloads the
CPU from I/O networking tasks, improving performance and scalability.
