eventually operate over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000Mbps-capable backbone/server connection creates a flexible foundation for the next generation of network technology products.

The DGE-500SX

Speed

The DGE-500SX transmits and receives data at one gigabit per second (1Gbps or 1000Mbps). Its full-duplex (only) operation mode enables it to transmit and receive data simultaneously, effectively doubling the amount of data being handled and giving it an actual top speed of 2Gbps. This huge amount of throughput can be used to connect highly active or bandwidth- hogging computers and servers directly to your network either through a switch port on your backbone, or through a departmental switch. The DGE-500SX also includes very large (96 KB) data buffers designed to significantly increase network performance by virtually eliminating buffer overruns.

PCI Interface

The DGE-500SX attaches to the host computer via the fast and efficient PCI bus. The host PCI slot can be either 32- or 64-bit, and should be compliant with PCI v2.1 or later. Make sure the host computer has a 64-bit PCI bus in order to take advantage of the full-duplex speed enhancement.

In addition, the DGE-550SX uses the following advanced features to maximize the utilization of the PCI bus and reduce overhead on the system CPU:

•Bus Master technology - the NIC masters the PCI bus, freeing the CPU from PCI bus management duties.

•Direct Memory Access (DMA) – enables the NIC to write directly to the system memory, freeing the CPU from many memory management duties.

•Burst transfers – full bandwidth packet bursting across the PCI bus increases the throughput for small packets by coalescing transfers.

•Memory buffers - Dual transmit and receive FIFO buffers allow for simultaneous reading and writing of data.

VLAN

The DGE-500SX supports IEEE 802.1Q VLAN tagging and filtering at the chip level, and works with any IEEE 802.1Q compliant switch. The IEEE 802.1Q standard describes a methodology by which packets of data going through networking devices can be inserted with, or stripped of, VLAN identification information. VLANs can increase the efficiency and provide extra security for your network.

Product Features

Designed for versatility and performance, the DGE-500SX adapter provides the following features:

•Fully compliant with IEEE 802.3z 1000BASE-SX Gigabit Ethernet standards and IEEE 802.3 Ethernet standards.

•Plug-and-Play installation.

•Maximum 1Gbps (1000Mbps) transmit and 1Gbps receive for a total of 2Gbps data throughput.

•Full-duplex operation only.

•PCI v2.2 compliant.
