There seems to be a problem with the cdimage server containing the
Feisty Server CD image (long time outs, less than 1KB/s transfer rate)
so I've installed Feisty Alternate x86 command-line on the Dell
PowerEdge 6300/550 in order to get some information on the hardware.
Note that after the installer reboots the system the PERC/2 controller
reports unflushed data in the cache and refuses to boot the kernel. It
requires a power-off followed by a full system memory count (which can
take over 5 minutes) to clear the situation.

$ uname -a
Linux PowerEdge6300 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 
GNU/Linux

The PERC/2 controller is:
03:03.0 RAID bus controller [0104]: Digital Equipment Corporation DECchip 21554 
[1011:0046] (rev 01)

It is managed by aacraid:
