I/O bus architecture
PCIe x16
Slot requirement
For details about slot priorities and placement rules, see PCIe adapter placement rules and slot
priorities (http://www.ibm.com/support/knowledgecenter/POWER8/p8eab/
p8eab_mtm_pciplacement.htm) and select the system you are working on.
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 cable. You can choose to cable just one port.
Voltage
3.3 V
Form factor
Short, low-profile (FC EC3E)
Short, will full-height tailstock (FC EC3F)
Maximum number
For details about the maximum number of adapters that are supported, see PCIe adapter
placement rules and slot priorities (http://www.ibm.com/support/knowledgecenter/POWER8/
p8eab/p8eab_mtm_pciplacement.htm) and select the system you are working on.
Operating system or partition requirements
The adapter is supported on the following versions of the operating systems, depending on the system
you are using:
v
Linux:
– Red Hat Enterprise Linux 7.2, little endian, or later, with Mellanox OFED 3.1, or later
– Ubuntu Server 16.04, or later with Mellanox OFED 3.3, or later
– Ubuntu Server 14.04.3, or later with Mellanox OFED 3.3, or later
PCIe3 LP 1-port 100 Gb EDR InfiniBand adapter x16 (FC EC3T and EC3U; CCIN
2CEB)
Learn about the specifications and operating system requirements for the feature code (FC) EC3T adapter.
Overview
FC EC3T and EC3U are both the same adapter with different feature codes. FC EC3T is a low-profile
adapter and FC EC3U is a full-height adapter.
The PCIe Gen3 low profile x16 1-port EDR InfiniBand adapter provides high-speed connectivity with
other servers or InfiniBand 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.
Note:
v The ambient environment must be less than or equal to 25°C (Celsius) and 500 M (meters) when using
12x LFF (large form factor) HDDs (hard disk drives) in the 8348-21C.
v For no ambient restrictions in the 8348-21C, keep at least two of three bays empty of LFF HDDs in the
leftmost drive column.
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.
Figure 50 on page 52 shows the adapter.
