EM964 PCI Quartet is a 32-bit bus mastering Ethernet adapter which simply and cost-effectively optimizes PCI Local Bus server performance. The EM964 PCI Quartet adapter can support up to four network segments on separate channels, all at full cable bandwidth. The advanced solution for expanding networks Like most PC bus architectures, PCI is electronically limited by the number of slots it can support. PCI machines can have a maximum of five slots, but many have only two or three PCI slots. This restricts the number of network segments a PCI server can handle. The Quartet's four-channel design solves this problem and gives PCI servers the power of four Ethernet adapters in a single board. Quartet uses an on-board PCI-to-PCI bridge to extend the machine's internal PCI bus. This minimizes the load on the PCI bus and makes it possible for EM964 PCI Quartet to support all four network channel at full cable bandwidth. Each channel is fully independent, and transparent to BIOS except during configuration. Full Duplex Ethernet (FDE) capability can be easily enabled for each channel to double the cumulative system throughput in switched Ethernet networks. The Quartet adapter has completely independent transmit and receive circuitry for true 20 Mbits/sec. operation on each channel at Minimum Interframe Spacing. Cumulative throughput with FDE on all four channels is 80 Mbits/sec. Full Duplex Ethernet servers using the Quartet adapter can handle receive and transmit requests simultaneously. As a result, workstations can take advantage of faster service.
