iSeries I/O adapters and controllers 369
Draft Document for Review October 18, 2004 5486IOA.fm
When used as a Direct Attached Adapter for Linux or AIX, order the #0643 in
place of the #5706. The #5706 is a Customer Install Feature.
#5707 PCI-X 1Gbps Ethernet-SX IOA
The #5707 PCI-X 1 Gbps Ethernet-SX IOA is a 2-Port Gigabit Ethernet-SX
PCI-X Adapter that provides 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. The adapter supports
distances of 260m for 62.5 micron Multi Mode Fiber (MMF) and 550m for 50.0
micron MMF.
i5/OS V5R3 for adapter #5707 does not supports a function called
Large Send or
sometimes known as
TCP Segmentation. This function offloads the TCP
segmentation operation from the IP layer to the adapter for outgoing (transmit
side) TCP segments. AIX 5L for POWER V5.2 or later supports this function
i5/OS V5R3 for adapter #5707 does not supports a function known as
Checksum
Offload, which offloads the TCP/UDP Checksum Operation or workload from the
CPU to the adapter. AIX 5L for POWER V5.2 or later, SUSE Linux Enterprise
Server 9 for POWER with 2.6 kernel can support these functions.
The #5707 IOA does not require a PCI IOP. The IOP functions are already
integrated into the IOA.
There are no additional restrictions of where the #5707 can be placed. The
system recognizes IOP-less cards and handles them appropriately, regardless of
where they are placed (in front of or behind IOPs).
The 2-Port IBM Gigabit Ethernet-SX PCI-X Adapter incorporates an LC type
connector on the card.
Note the following restrictions:
Half Duplex (HDX) mode is not supported.
Systems Network Architecture (SNA) is not supported.
A cross-over cable is not supported.
It is supported in Models 520, 550, 570, and 595 with i5/OS V5R3.
When used as a Direct Attached Adapter for Linux or AIX, order the #0644 in
place of the #5707. The #5707 is a Customer Install Feature.
Note: For optimum performance, place the adapter in a 64-bit PCI-X card slot
whenever possible.
