10GigEthr-02 (iexgbe) B.11.31.1205 Ethernet Driver Release Notes

1 10GigEthr-02 overview
The 10GigEthr-02 bundle contains the PCIe 10 Gigabit Ethernet iexgbe driver. This driver supports
the following 10 Gigabit Ethernet products and LOMs:
HP Integrity Server LOM
PCIe 10 Gigabit Mezzanine Ethernet
Cards
PCIe 10 Gigabit Stand-up Ethernet
cards
BL860c i2NC532m (part number 467799-B21)AM225A 10GbE-SR (fibre) adapter
BL870c i2AM232A 10GbE-LR (fibre) adapter
BL890c i2AM233A 10GbE-CR (copper) adapter
Integrity Superdome 2
NOTE: The HP-UX ioscan utility shows AM225A, AM232A and AM233A cards all as
“AM225A”. This is because the only difference between the cards is the type of SFP module that
is used. Since the cards are functionally equivalent at the operating system level, ioscan does
not distinguish between them.

cards, see the following documents:

1.1 Features
The iexgbe driver is a PCIe 10 Gigabit Ethernet driver that can support the stand-up, mezzanine,
and LAN on motherboard (LOM) technologies for a variety of platforms. It is the first 10 Gigabit
Ethernet driver to support the HP Virtual Connect Flex-10 interface on server blade platforms. Before
HP Virtual Connect was introduced, only two interconnect choices were available for connecting
server blades to a network — pass-through devices and switches. Pass-through devices 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 — which reduces cables without adding switches to manage and
provides many other advantages. For more information about HP Virtual Connect, see the following
website:

Other notable features provided by the iexgbe driver include:
• Transmit CKO and TSO for IPv4
• Receive CKO for IPv4
• Flex-10 bandwidth allocation
• Multiple receive queues
