(#4961) IBM Universal 4-Port 10/100 Ethernet Adapter

IBM Universal 4-Port 10/100 Ethernet Adapter is a single slot, long, 64-bit, 33 MHz PCI adapter supporting 4 industry standard Ethernet 10 Base-T or 100 Base-T interfaces either half or full duplex. Each port is provided with it's own RJ-45 connector for attachment to standard CAT-3/5 Unshielded Twisted Pair (UTP) cable. The adapter is IEEE 802.3u compatible and provides full auto-negotiation for detecting speed and duplex capability across each port. Network boot capability and Network Install Manager (NIM) capability are available using this adapter if no specific limitation is stated. The IBM Universal 4-Port 10/100 Ethernet Adapter (#4961) should be considered where maximum port density is required per I/O card slot. But, for high end systems, where card slots are not the limiting factor and maximum throughput is required, the single port IBM 10/100 Mbps Ethernet PCI Adapter II (#4962) or the IBM 10/100 Mbps Ethernet PCI Adapter (#2968) are the preferred solutions. Below are some performance factors to consider when choosing the right adapter for your needs. These performance comparisons are based on all four ports of the IBM Universal 4-Port 10/100 Ethernet Adapter (#4961) being active.

• With all four ports under full bandwidth conditions, a single IBM Universal 4-Port 10/100 Ethernet Adapter (#4961) is expected to deliver up to 3 times the comparable performance of a single IBM 10/100 Mbps Ethernet PCI Adapter II (#4962) or the IBM 10/100 Mbps Ethernet PCI Adapter (#2968).
• Under most conditions, each port of the IBM Universal 4-Port 10/100 Ethernet Adapter (#4961) is expected to perform at greater than 50% the throughput of the single port of the IBM 10/100 Mbps Ethernet PCI Adapter II (#4962) or the IBM 10/100 Mbps Ethernet PCI Adapter (#2968).

Note: The resulting performance in your environment compared to the above may vary and depends upon the RS/6000 model, the I/O configuration, and associated workload of your applications.
