10GigEthr-03 (iocxgbe) B.11.31.1209 Ethernet Driver Release Notes, Edition 3

are simple but require too many cumbersome cables and create complexity. Blade switches reduce

the number of cables but add more management responsibilities for LAN and SAN administrators.

In both cases, multiple people are needed to perform very simple server tasks. Only HP offers the

third choice — HP Virtual Connect.

Other notable features provided by the iocxgbe driver include:

• Transmit Checksum Offload (CKO) and TCP Segmentation Offload (TSO) for IPv4

• Receive CKO for IPv4

• Flex-10 bandwidth allocation

• Multiple receive queues

• Receive Side Scaling (RSS) with TCP and UDP

• TCP segment reassembly in driver

• Jumbo Frames

• Multicast and Promiscuous mode

• IPv6

• IEEE 802.1Q VLAN tagging and stripping in hardware

• Interrupt migration

• Interrupt coalescing

• Link handling

• DLKM

• APA aggregate mode

• APA failover mode (LAN Monitor)

• HP Serviceguard

• PCI OLRAD

• PCI Error handling and recovery

• HP Integrity Virtual Machines (HPVM)

• vPars V6

• DIO (direct I/O)

• HP-UX LAN provider

• MIB and driver statistics

• Configurable using SMH or nwmgr

• nettl tracing/logging

New and changed features in this release

New features

New features introduced with 10GigEthr-03 (iocxgbe) B.11.31.1209

This release introduces performance enhancements to the existing driver and adds support for

Online Addition, Replacement, and Deletion (OL*) of PCIe standup network cards on Superdome

2 servers. With this feature, the server does not need to be powered off to perform any of these

operations on a network card.

1. Only LACP mode is supported with APA aggregation with 10GbE links. APA aggregate mode is not supported with

server blades over Virtual Connect interconnects. Virtual Connect does not support aggregates (trunks), LACP, or

otherwise on the downlinks side.
