Product Overview
The AB287A PCI-X 10 Gigabit Ethernet cards have the following features and requirements:
PCI-X 133 MHz, 64-bit operation. Best performance is achieved by putting the cards in the high-performance or
dual-rope” slots. To identify which slots are the high-performance (dual rope) slots in a particular system, please refer to
the hardware users’ guide for each system.
Conforms to IEEE 10 GigE Base-SR using multi-mode fiber. Operating distances from 7 ft to 984 ft (2 to 300 meters). It’s
still Ethernet.
Operates on 64-bit HP-UX 11i v2 or 11i v1 on HP Integrity and HP 9000 servers.
Supports use of Jumbo Frames. The ixgbe driver on HP-UX 11i v1 or v2 supports Jumbo Frames with a maximum
transmission unit (MTU) of 9000 bytes. Jumbo frames achieve much higher throughput than the standard 1500 MTU
before reaching optimum CPU utilization. A backup server using jumbo frames to multiple clients would be an ideal
setup.
On board TCP Segmentation Offload (TSO) of IPv4 that can reduce the server’s load for certain applications especially
ones transmitting large amounts of data. See details in the TSO section of this document.
On board Checksum Offload (CKO) that increases server CPU efficiency and performance over TCP, UDP, and IPv4. See
details in the CKO section of this document.
All on board data and control structures on the 10GigE card are protected by SEC (single error correcting), DED (double
error detecting) ECC (Error Correcting Code).
Supports HP Serviceguard and LAN_MONITOR mode of Auto-Port Aggregation (APA) for high availability. The
LACP_AUTO, FEC_AUTO, and MANUAL modes of the HP APA product are not supported.
The HP-UX 11i v2-based version of the 10 Gigabit product supports logical multi-queues, that can substantially improve
network bandwidth especially if there is a mix of applications -- because all packets are not sent to the same destination
port. Beginning with the December 2005 release, this feature assigns inbound packets to receive queues based on a
packet's destination-port and can be enabled to work automatically. This feature is critical to achieving good sustained
throughput. Without making use of multi-queue, a single CPU will be used for interrupt processing on the receive path. If
the CPU becomes over-saturated (very likely if the MTU is set to 1500, and there is a heavy traffic load), the card will not
be able to sustain link rate. With multi-queue configured, different flows of traffic will be routed to different CPUs thereby
helping to avoid saturating a CPU.
Driver version B.11.23.0612 supports UDP traffic over the destination port-based multi-queues.
10 Gigabit Ethernet multi-queue functionality is not available on HP-UX 11i v1.
Supports virtual LANs (VLANs) to provide increased network flexibility. A Virtual LAN (VLAN) is a logical or virtual
network segment that can span multiple physical network segments. VLANs isolate broadcast and multicast traffic by
determining which destinations should receive that traffic, thereby making better use of switch and end-station resources.
With VLANs, broadcasts and multicasts go only to the intended nodes in the virtual LAN. This feature is described in
Using HP-UX VLANs on http://docs.hp.com.
Configuration through graphic user interface SAM on HP-UX 11i v1 and HP-UX 11i v2, or SMH on HP-UX 11i v3, or
command line.
Interrupt Migration via the intctl command.
Two LED indicators and one duplex LC connector. One LED is for the Link and one LED is for Activity.
•The 10GbE Base-SR port operates only at 10 Gbit/s and only in full-duplex mode.
