v FC EN16: PCIe3 LPX 4-port 10 GbE SR Adapter
The PCIe3 4-port 10 GbE SR Adapter is a PCI Express (PCIe) generation 3, x8, short form-factor adapter.
The adapter provides four 10 Gb small form-factor pluggable (SFP+) optical SR transceiver ports, as
shown in Figure 86 on page 191. The ports have little connector (LC) duplex-type connectors and utilize
shortwave laser optics and MMF-850nm fiber cabling. See “Cables” on page 191 for more information
about the optical cables. The adapter supports the Ethernet network interface controller (NIC) function
and also provides SR-IOV NIC support. SR-IOV capability for the NIC function is supported with the
appropriate firmware and operating system level for any of the four ports. Enabling the SR-IOV function
requires an HMC.
The adapter provides the following features:
v Four 10 Gb ports that can function in the NIC mode
v AIX Network Installation Management (NIM) support
v The adapter supports interrupt moderation to deliver increased performance while significantly
reducing processor utilization
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 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
