[SGVLUG] Video server

[Matt Campbell]

Hi Matti, thanks for answering.

The details are on the site;).  There are 12 WD RE3 1TB drives hooked up to
an Adaptec 31205 SAS/SATA RAID controller.  This appears as /dev/sdb and has
a single Ext2 partition on it.

The 31205 is a PCIe8 card supported on RedHat and SUSE directly and reported
working on Fedora, Ubuntu and others.  It looks like they released the
driver source code for a number of distros.

What other details are useful?

Matt
