1984-8203 - IBM Power6 E4A 2-Port Gigabit Ethernet-SX PCI-X Adap

The IBM Power6 8203-E4A (#1984) IBM 2-Port Gigabit Ethernet-SX PCI-X Adapter

The IBM 2-Port Gigabit Ethernet-SX PCI-X Adapter 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. AIX Network Install Manager (NIM) boot capability is supported with this adapter.

A function called 'Large Send' or sometimes known as TCP Segmentation is also provided by this adapter. This function offloads the TCP segmentation operation from the AIX IP layer to the adapter for outgoing (transmit side) TCP segments. Another function known as "Checksum Offload" which offloads the TCP/UDP Checksum Operation or workload from the CPU to the adapter is also provided.

The IBM 2-Port Gigabit Ethernet-SX PCI-X Adapter The IBM Power6 8203-E4A (#5707) should be considered where maximum port density is required per I/O car slot. For a suggested maximum number of adapters taking performance into consideration, refer to the RS/6000 & pSeries PCI Adapter Placement Reference SA38-0538. If card slots are not the limiting factor and maximum throughput is required, the single port IBM Gigabit Ethernet-SX PCI-X Adapter The IBM Power6 8203-E4A (#5700) is the preferred solution.

Note: For optimum performance, the adapter should be placed in a 64 bit PCI-X card slot whenever possible.

Note: The 2-Port IBM Gigabit Ethernet-SX PCI-X Adapter incorporates an LC type connector on the card. This new, smaller form factor connector is being used by the industry for the next generation of fiber optic networks. If connecting into an older, existing SC type connector network, an LC-SC 62.5 Micron Fiber Converter Cable The IBM Power6 8203-E4A (#2459) or LC-SC 50 Micron Fiber Converter Cable The IBM Power6 8203-E4A (#2456) is required.

Limitation: Half Duplex (HDX) mode is not supported.

Attributes provided: Two full-duplex 1000Base-SX fiber connections to a Gigabit Ethernet LAN(s).

Attributes required: One available PCI or PCI-X card slot
