Ethernet Adapters conform to IEEE 802.3 standards.

Press Release Summary:



Dual-Port Ethernet PCI-X adapters expand network connectivity options for IBM eserver pSeries(TM) and RS/6000® systems. Full-duplex Gigabit Ethernet adapter can be configured to run each port at 10, 100, or 1000 Mbps data rate and supports jumbo frames when running at 1000 Mbps speed. Gigabit Ethernet-SX PCI-X Adapter offers 1000 Base-SX full-duplex Ethernet LAN connections with throughput on standard short-wave multimode optical cable that conforms to IEEE 802.3z.



Original Press Release:



IBM 2-Port Gigabit Ethernet PCI-X Adapters Expand IBM eserver pSeries and RS/6000 Systems Connectivity



Overview

New PCI-X adapters expand the network connectivity options for IBM eserver pSeries(TM) and selected RS/6000® systems.

IBM 2-Port 10/100/1000 Base-TX Ethernet PCI-X Adapter

This full-duplex, dual ported, Gigabit Ethernet adapter can be configured to run each port at 10, 100, or 1000 Mbps data rates. The adapter conforms to the IEEE 802.3ab 1000Base-T standard, which defines Gigabit Ethernet operation over distances up to 100 meters using four pairs of CAT-5 balanced copper cabling -the type of cabling within most buildings.

Performance can be improved using these features:

o Jumbo frames (at 1000 Mbps speed), which can deliver a significant increase in throughput with a significant decrease in CPU utilization

o Large Send, which offloads the TCP segmentation operation from
the AIX IP layer to the adapter for outgoing TCP segments

o Checksum Offload, which offloads the TCP/UDP checksum operation or workload from the CPU to the adapter

IBM 2-Port Gigabit Ethernet-SX PCI-X Adapter

This adapter offers two 1 Gbps (1000 Base-SX) full-duplex Ethernet LAN connections with throughput on a standard shortwave multimode optical cable that conforms to the IEEE 802.3z standard. This adapter also improves performance with the same jumbo frames and Large Send features as for the Base-TX Ethernet PCI-X Adapter.

Key Prerequisites

o A supporting pSeries or RS/6000 system
o One available PCI or PCI-X slot
o AIX 5.1 with May 2003, updates or later software
o AIX 5.2 with May 2003, updates or later software

Planned Availability Date

May 30, 2003

At a Glance

These new adapters offer flexible network connectivity:

o 2-Port 10/100/1000 Base-TX Ethernet PCI-X Adapter: A full-Duplex, dual-ported, Gigabit Ethernet adapter that supports
jumbo frames when running at the 1000 Mbps speed

o 2-Port Gigabit Ethemnet-SX PCI-X Adapter: An adapter offering two 1 Gbps (1000 Base-SX) full-duplex Ethernet LAN connections and performance enhancements like Large Send and Checksum Offload
