Vortex has Linux drivers for 2.0.x and 2.1.x Linux kernels (I've tried
both, and both work).  They can be seen at:

Using RAID-0 I've been able to get 20MBytes/sec write performance
(with a "dd of=/dev/sda if=/dev/zero bs=65536 count=65536").  RAID-5,
I get under 10MBytes/sec.  Read times are faster.

They have a configuration tool called gdtmon, and a version that works
in Linux.  But, their scsi bios requires a video card (no headless
operation).
