4.7. 10/100/1000 Base-TX Ethernet PCI-X Adapter -DCCG164
The 10/100/1000 Base-TX Ethernet PCI-X Adapter is a full-duplex Gigabit Ethernet adapter designed
with highly integrated components to optimize cost and performance. This adapter can be configured
to run at 10, 100, or 1000 mbps data rates. The adapter interfaces to the system via the PCI-X bus and
connects to the network using a 4-pair CAT-5 Unshielded Twisted Pair (UTP) cable for distances of up
to 100 m. AIX Network Install Manager (NIM) boot capability is supported with this adapter. The
adapter conforms to the IEEE 802.3ab 1000 Base-T standard. The adapter also supports jumbo frames
when running at the 1000 mbps speed.
Note:
For optimum performance, adapter should be placed in a 64 bit PCI-X card slot.

AIX 5.1
4.7.1. 2-Port 10/100/1000 Base-TX Ethernet PCI-X Adapter - DCCG165 for PL220T,
DCCG168 for PL240T and PL420T
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:
•
Jumbo frames (at 1000 Mbps speed), which can deliver a significant increase in throughput
with a significant decrease in CPU utilization.
•
Large Send, which offloads the TCP segmentation operation from the AIX IP layer to the
adapter for outgoing TCP segments.
•
Checksum Offload, which offloads the TCP/UDP checksum operation or workload from the
CPU to the adapter
Quantities per Supported System:
•
DCCG165 for PL220T: 5 in base
•
DCCG168 for PL240T: 4 in base
•
DCCG168 for PL420T: 6 in base
Software Requirements:
DCCG165: AIX 5.1 and later for PL220T
DCCG168: AIX 5.1 and later for PL240T and PL420T
