Pcie3 2-Port 100 Gbe Nic & Roce Qsfp28 Adapter - IBM Power System Series Manual

Cables
The two 100 Gb ports have QSFP28 connections. These 100 Gb ports support industry standard EDR
DAC or optical cables.
Note: One adapter supports both types of cables. You can choose to cable just one port.
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/

PCIe3 2-port 100 GbE NIC & RoCE QSFP28 Adapter (FC EC3L and EC3M; CCIN 2CEC)
Learn about the specifications and operating system requirements for the feature code (FC) EC3L and
EC3M adapter.
Overview
FC EC3L and EC3M are both the same adapter with different tail stock brackets. FC EC3L is a low-profile
adapter and FC EC3M is a full-height adapter.
The PCIe3 2-port 100 GbE NIC & RoCE QSFP28 Adapter is a PCI Express (PCIe) generation 3 (Gen3), x16
adapter. The adapter provides two 100 Gb QSFP28 ports. The PCIe3 2-port 100 GbE (NIC and RoCE)
QSFP28 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 CPU overhead by more efficiently using
memory access. This offloads the CPU from I/O networking tasks, improving performance and scalability.
Note: Each port maximum of 100 Gb assumes that no other system and or switch bottlenecks are
present. The adapter allows full bandwidth for a single port in a PCIe3 slot and up to 128 Gb/s minus
overheads for both ports.
