adapter is a high-performance adapter that consolidates traffic for networking. The link aggregation and
failover features of the adapter make it suitable for critical network applications that require redundancy
and high availability.
The two 10 Gb are SFP+ and do not include a transceiver. Active Copper twinax cables up to 5 meter in
length are supported such as provided by feature codes EN01, EN02 or EN03. A transceiver is included
with these cables. See "Cables" on page 171 for details. Each 10 Gb port provides Ethernet connectivity
with a nominal data rate of 10 Gbps (gigabits per second). Figure 76 on page 170 shows the FC EN0U
adapter.
Each of the 1 Gb RJ45 port provides Ethernet connectivity at a data rate of 1 Gbps. Each of the 1 Gb ports
is connected with a 4-pair, CAT-5 unshielded twisted pair (UTP) cable or with a cable of higher
specification, and is supported for distances of up to 100 meters. In addition to 1 Gb (1000 Mb) networks,
100 Mb networks are also supported.
The adapter provides the following features:
v The adapter is a PCIe2 NIC network convergence adapter.
v The 10 Gb ports can function in the NIC mode.
v The adapter can be used as the host local area network (LAN) adapter.
v The adapter supports interrupt moderation to deliver increased performance while significantly
reducing processor utilization
v The adapter supports dual port operation in any PCIe3 or PCIe2 slot.
v The adapter supports auto-negotiation, full-duplex only.
v The adapter supports multiple media-access control (MAC) per interface.
v The adapter supports integrated media-access control (MAC) and physical layer (PHY).
v The adapter supports the following standards for the different ports and functions:
– 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
