Click box to request more information

Quartet/4OO is the ultimate performance adapter for PCI servers on 100 Mbitlsec. Fast Ethernet networks. With four channels on a single board and optional Full Duplex support, Quartet/4OO has the features today's 32-bit Fast Ethernet servers need to handle Microsoft Windows, graphics, multimedia, database, and mission-critical applications. This innovative adapter provides ample bandwidth for even the most demanding networks. Quatlet/4OO can support up to four network segments on separate channels-all at full cable bandwidth for cumulative throughput of 400-800 Mbitslsec. Add to this the advantages of the PCI Local Bus architecture, and Quartet/4OO is clearly the superior Fast Ethernet solution.

The ultimate innovation in Fast Ethernet

Ten times faster than traditional 10 Mbit/sec. Ethernet adapters, the Quartet4OO adapter is ideal for servers which need high throughput and low CPU utilization to power large amounts of data across the network. Independent 2 KByte transmit and 4 KByte receive FIFOs (First In, First Out memory) on-board and powe@ul DMA capability mean that Quartet400 can handle increased bus latencies with decreased sensitivi- ty to load.

Quartet400 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 Quartet400 to support all four network channels at full cable bandwidth. Each channel is fully independent, and transparent to BIOS except during configuration.

For maximum throughput, Quartet400 includes Full Duplex Fast Ethernet (FDFE) capability which doubles the cumulative system throughput rate in switched Ethernet networks. FDFE suppose is easily enabled on each port via software configuration. The QuaqeV400 adapter has completely independent transmit and receive circuitry for true 200 Mbits/sec. opera- tion on each channel at Minimum Interframe Spacing. Cumulative throughput with FDFE on all four channels is 800 Mbitstsec. Full Duplex Fast Ethernet servers provide workstations with the maximum pe@or- mance advantage.
