Allied Telesis, a provider of secure Ethernet/IP access technology, has launched a 32-bit PCI Gigabit fibre adapter card designed to reduce the CPU usage of desktop PCs.
The AT-2916SX enables IT departments to upgrade network throughput from 100 to 1,000mbps on their existing fibre infrastructure. The card is available with an SC connector for existing 100mbps fibre cabling, and an LC connector for 1,000mbps fibre connectivity.
The card has a built-in preboot execution environment (PXE) as standard. PXE remote boot Rom lets network administrators boot a PC remotely and carry out software upgrades and diagnostics without physically visiting the machine, making maintenance and upgrade tasks easier and quicker.
Allied Telesis said the AT-2916SX was designed to reduce CPU usage by offloading some tasks associated with processing TCP/IP data.
Support for calculating TCP, UDP and IP checksums is integrated into the adapter's hardware. The checksums are calculated in real time by the controller for both the receive and transmit paths. This improves the overall performance of the system while shifting these CPU-intensive tasks away from the host PC, according to Allied Telesis.
The AT-2916SX also includes link aggregation and load balancing, and can support up to 64 virtual Lans and four priority queues.
