PCIe3 2-port 10 GbE NIC & RoCE SFP+ copper adapter (FC EC37, FC EC38, FC EL3X, and FC EL53;
CCIN 57BC)
Learn about the specications and operating system requirements for the feature code (FC) EC37, FC
EC38, FC EL3X, and FC EL53 adapters.
Overview
The FC EC37 and FC EL3X are low-prole adapters, and the FC EC38 and FC EL53 are full-height
adapters.
The PCIe3 2-Port 10 GbE NIC & RoCE SFP+ adapter is a PCIe generation-3 (PCIe3), dual port, 10 Gigabit
Ethernet (GbE) adapter with a PCIe 3.0 host bus interface. The adapter provides two 10 Gb SFP+ ports for
copper twinax cabling. These cables also include copper transceivers. 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 signicantly greater bandwidth
with low latency and minimize CPU overhead by more efciently using memory access. This offloads the
CPU from I/O networking tasks, improving performance and scalability.
Active Copper twinax cables up to 5 meter in length are supported such as provided by FCs EN01, EN02
or EN03. A copper transceiver is included with these cables. See “Cables” on page 89 for details. Each
10 Gb port provides Ethernet connectivity with a nominal data rate of 10 Gbps (gigabits per second).
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
– 802.3x for flow control
– 802.3ad for load-balancing and failover
– IEEE 802.3ad and 802.3 for link aggregation
• The adapter provides message signal interrupts (MSI), MSI-X, and support of legacy pin interrupts.
• The adapter supports jumbo frames up to 9.6 KB.
• The adapter supports gigabit EtherChannel (GEC) with the existing software.
• The adapter supports TCP checksum offload transmission control protocol (TCP), user datagram
protocol (UDP), TCP segmentation Offload (TSO) for IPv4 and IPv6.
• Supports TCP segmentation or large send offload
• Supports EEPROM-SPI and single EEPROM
• Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain
Hazardous Substances in Electrical and Electronic Equipment
