My company, TeraSolutions, builds custom RAID storage systems and I'd be happy to put together a quote for you. Although wcarchive is currently using the DAC960SXI, I haven't been very happy with its performance and have since moved to the Viper II series of controllers from CMD. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com Pave the road of life with opportunities.
