The major motivation for migrating to an open source based system was cost. Previously, for almost a decade PAGASA used an SGI Irix supercomputer that cost over P200,000 (AUD$5200) a month to run. Since September 2007, the Debian Linux cluster has dropped that monthly figure down to around P10,000 (AUD$260).
