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/

PCIe4 x16, 1-port HDR 100 Gb InfiniBand ConnectX-6 adapter (FC EC6E; CCIN 590D)
Learn about the specifications and operating system requirements for feature code (FC) EC6E.
Overview
FC EC6E is a low-profile adapter. The PCIe4 x16 1-Port high data rate (HDR) 100 Gb InfiniBand (IB)
ConnectX-6 adapter is a PCI Express (PCIe) generation 4 (Gen4) x16 adapter. The adapter can be used in
a x16 PCIe slot in the system. The adapter enables higher HPC performance with new Message Passing
Interface (MPI) offloads, such as MPI Tag Matching and MPI AlltoAll operations, advanced dynamic
routing, and new capabilities to perform various data algorithms. The HDR 100 Gb adapter supports
connecting to an HDR 200 Gb switch by using HDR 100 Gb splitter cables (Direct Attach Copper-DAC or
Active Optical Cables-AOC). Splitter cables allow a single HDR 200 Gb switch port to connect to HDR 100
Gb adapter ports, doubling a typical HDR switch capacity from 40 ports to 80 ports. The HDR 100 Gb
