There is a line of Mylex DAC690-derived RAID controllers which comprise
the DEC/Compaq RaidArray 230 line.  You can find these on Ebay for
$30-50.  I have only tried the DAC690PD; some models require a firmware
upgrade to run FreeBSD/Linux.  This is an wide ultrascsi RAID board
based upon the Intel 960 chip.  There are configured using a
configuration utility that runs in ARC.  These controllers run fine, but
the largest drives they can be used with are 9.1 gig.

I have booted FreeBSD alpha on a AlphaServer 2100A with these and they
work fine.  I don't know how they will work on the OEM boards.

Cheers!
