For applications requiring increased throughput and High-Availability (HA) on server-based systems, American Portwell has introduced a new PCI-E Gen 2 (5 Gbit/s) quad copper Gigabit Ethernet adapter. Based on the Intel 82580EB controller, the NIC-51240 adapter includes a built-in watchdog timer (WDT) to switch to bypass mode for Ethernet ports on host system "hang" or power failure. Configuration of a selectable Normal/Bypass mode and software programmable WDT time-out setting is quick and easy.

The NIC-51240 also features both onboard LED and LED pin-out for LAN status and bypass mode to provide variable LED location for system integration; support for most network operating systems, including Linux, FreeBSD and Microsoft Windows; and PCI-E 2.0 x4 host interface. The new Ethernet adapter is PCI-E 2.0 5 Gbit/s solution-ready and backward compatible with PCI-E 1.0 2.5 Gbit/s bus. Its bypass function can be disabled completely for use as a regular Quad GbE port NIC-type adapter.

The PCI-E Gen2 offers a definite increase in throughput when compared with the PCI-E Gen 1. The inclusion of quad ports increases network reliability, and the adapter's support for most network operating systems allows for widespread deployment. In addition, NIC-51240's built-in bypass mode (failure or power-off) enables the unit to bypass a failed system and provide maximum uptime for the network. The Intel 82580EB controller operates at an economically low powered 4.2W and VMDq support of 8TX and RX queues of up to 8 VMs per port helps reduce I/O bottlenecks and latency, and increase throughput.
