The Advanced Weather Interactive Processing System (AWIPS) was first deployed in 1995-1999. Over the years, as new requirements warranted, the original AWIPS system design was supplemented with upgrades to existing hardware. In 2002, the decision was made to embrace LINUX as the OS for AWIPS. Over the past two years, the two headed UNIX workstations were replaced with three headed LINUX workstations and a pair of LINUX servers were added to assist in processing power needed for the additional applications and products. In 2004, the Government authorized the most aggressive tech refresh, that when completed, will have replaced nearly all of the original 1990’s equipment. Routers, X-terminals, UNIX servers, FDDI network, and firewalls are the major replacements planned. The new architecture makes use of commodity WINTEL servers and network attached storage to meet the current needs. The architecture is flexible to allow for additional servers to be added in the future to meet expanding needs. The benefits the NWS field sites will see are faster processing, and more communication and storage capacity for more products.
