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 13 on page 43 shows the FC EC2M adapter.
The adapter provides the following features:
v The adapter is a PCIe3 NIC network convergence adapter.
v The adapter supports RoCE and NIC functions but not concurrently on same adapter.
v 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
v The adapter provides message signal interrupts (MSI), MSI-X, and support of legacy pin interrupts.
v The adapter supports jumbo frames up to 9.6 KB.
v The adapter supports gigabit EtherChannel (GEC) with the existing software.
v The adapter supports TCP checksum offload transmission control protocol (TCP), user datagram
protocol (UDP), TCP segmentation Offload (TSO) for IPv4 and IPv6.
v Supports TCP segmentation or large send offload
v Supports EEPROM-SPI and single EEPROM
v Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain
Hazardous Substances in Electrical and Electronic Equipment
