For More Information Test Configuration The test configuration consisted of a 4-way (4-CPU), 800 MHz rp4440 cabinet with 16 Gigabytes of system memory and two A7012A PCI-X 2-port Gigabit Ethernet cards. The card and TSO performance were then measured in a single partition system. The A7011A /A7012A were in slots 7 and 8, the dual-rope or higher-performance slots. The Gigabit Ethernet test load was generated by connecting the Gigabit Ethernet ports on the cards to one HP 9304M Procurve Routing Switch. Eight 2-way rx2600s each containing a single PCI 1000Base-SX card were connected to the switch (2 rx2600s per port). NOTES: • The networking and I/O performance of the A7011A is identical to the A7012A. • The observed performance results are consistent across all of the same type of I/O slots of the system. • The core I/O card in the rp4440 had only minimal site LAN traffic during performance tests.

Taking the Next Step If you would like to try the TSO product, you can obtain an HP-UX 11i v 1.0-based copy for either the iether or igelan drivers at: http://software.hp.com under "enhancement releases and patch bundles." TSO for both the iether and igelan drivers will be available on the September 2004 OE release of HP-UX 11i v 2.0. On HP-UX 11i v 2.0 versions prior to the September 2004 OE, the iether driver supporting TSO is available as patch PHNE_30279. Please note that you would need to install PHNE_30773 and TOUR 2.0 (http://software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=TOUR) in addition to PHNE_30279 in order to enable this functionality. Also note that this functionality is disabled by default on HP-UX 11i v2.0 and can be enabled/disabled on a per interface basis.

Test Configuration
The test configuration consisted of a 4-way (4-CPU), 800 MHz rp4440 cabinet with 16
Gigabytes of system memory and two A7012A PCI-X 2-port Gigabit Ethernet cards. The
card and TSO performance were then measured in a single partition system. The A7011A
/A7012A were in slots 7 and 8, the dual-rope or higher-performance slots.
The Gigabit Ethernet test load was generated by connecting the Gigabit Ethernet ports on
the cards to one HP 9304M Procurve Routing Switch. Eight 2-way rx2600s each containing
a single PCI 1000Base-SX card were connected to the switch (2 rx2600s per port).
NOTES:
•
The networking and I/O performance of the A7011A is identical to the A7012A.
•
The observed performance results are consistent across all of the same type of I/O slots
of the system.
•
The core I/O card in the rp4440 had only minimal site LAN traffic during performance
tests.

Taking the Next Step
If you would like to try the TSO product, you can obtain an HP-UX 11i v 1.0-based copy for
either the iether or igelan drivers at:
under “enhancement releases
and patch bundles.”
TSO for both the iether and igelan drivers will be available on the September 2004 OE
release of HP-UX 11i v 2.0. On HP-UX 11i v 2.0 versions prior to the September 2004 OE,
the iether driver supporting TSO is available as patch PHNE_30279. Please note that you
would need to install PHNE_30773 and TOUR 2.0
(
) in
addition to PHNE_30279 in order to enable this functionality. Also note that this
functionality is disabled by default on HP-UX 11i v2.0 and can be enabled/disabled on a
per interface basis.
