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/
set2/sas/f/lopdiags/home.html).
• For support details, see the Linux Alert website (http://www14.software.ibm.com/webapp/set2/sas/f/
lopdiags/info/LinuxAlerts.html).
PCIe3 LP 2-Port 10 GbE NIC and RoCE SR Adapter (FC EC2M, FC EC2N, FC EL40, and FC EL54; CCIN
57BE)
Learn about the specifications and operating system requirements for the feature codes (FC) EC2M,
EC2M, EC2N, EL40, and EL54 adapters.
Overview
FC EC2N and FC EL54 are full-height adapters. FC EC2M and FC EL40 are low-profile adapters. The names
of these two adapters are:
• FC EC2N and FC EL54: PCIe3 2-Port 10 GbE NIC and RoCE SR adapter
• FC EC2M and FC EL40: PCIe3 LP 2-Port 10 GbE NIC and RoCE SR adapter
This PCIe generation 3 adapter provides two 10 Gb SR optical fiber ports. The adapter is a converged
network adapter supporting both NIC and IBTA RoCE standard. RoCE is Remote Direct Memory Access
(RDMA) over Converged Ethernet. Using RoCE, the adapter can support significantly greater bandwidth
with low latency and minimize CPU overhead by more efficiently using memory access. This offloads the
CPU from I/O networking tasks, improving performance and scalability.
The adapter has two preinstalled optical transceivers. Little connector (LC) type connectors connect the
adapter to standard 10-Gb SR optical cabling and provide up to 300 m (984.25 ft) cable length. The two
transceiver ports are used for connectivity with other servers or switches in the network. Each port
provides Ethernet connectivity with a nominal data rate of 10 gigabits per second (Gbps). The link
aggregation and failover features of the adapter are ideal for critical network applications that require
redundancy and high availability. Figure 12 on page 75 shows the low-profile adapter and Figure 13 on
page 76 shows the full-height adapter.
The adapter provides the following features:
• The adapter is a PCIe3 NIC network convergence adapter.
• The adapter supports RoCE and NIC functions but not concurrently on same adapter.
• The adapter supports the following standards for the different ports and functions:
– AIX NIM and Linux Network Install are supported
– IBTA RoCE v2 support
– IEEE 802.3ae in the 10 GbE ports
– 802.3ab in the 1 GbE ports
– Ether II and IEEE 802.3 for encapsulated frames
– 802.1p for setting up priority levels in tagged VLAN frames
– 802.1Q for VLAN tagging
