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/xcentral/).
• 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 x16 1-port 100 Gb EDR InniBand adapter (FC EC3T and EC3U; CCIN 2CEB)
Learn about the specications and operating system requirements for the feature code (FC) EC3T and
ECTU adapter.
Overview
FC EC3T and EC3U are both the same adapter with different feature codes. FC EC3T is a low-prole
adapter and FC EC3U is a full-height adapter.
The PCIe Gen3 x16 1-port EDR InniBand adapter provides high-speed connectivity with other servers or
InniBand switches. A maximum of 100 G assumes that no other system and or switch bottlenecks are
present. The x16 adapter allows full bandwidth in a PCIe Gen3 slot.
The 100 Gb port has QSFP28 connection which supports industry standard EDR cables, either EDR DAC
cables or EDR optical cables. One adapter can support either or both types of cable. You can choose to
cable just one port if wanted.
Note: The Virtual Protocol Interconnect (VPI) feature is not supported on this adapter. The adapter must
be used only as an InniBand adapter.
