fun. not sure where the 15 drives bit is - i assume an external PV220S ? but they only
take 14 drives...

well if you are using a PERC3/DC then it is hardware raid and you don't 'format' the
drives. you create your LUNs in hardware and then you fdisk and format the arrays
as you have partitioned them. it's no different to doing this on a single disk
install. the OS will just see sda, sdb etc depending on the number of LUNs created
and sda1, sda2 etc depending on how many partitions.

the linux documentation project is a good place to start,
e.g http://ldp.planetmirror.com and then find your closest mirror.
there is also a user manual for the perc3/dc which may be worthwhile.

you can install RHL 9 on this machine yep. whether you need the enterprise version
depends on what you plan to do with the machine. for example will you need any
security patches or bug fixes to the machine after April 2004 ? then you will
want to consider RHEL3. do you need to run anything 'business critical' ? then
you'll want RHEL3.. do you want to run a large database or get support from Red Hat
for problems then..
> - Is there any software out there to manage/automate this install/config process? There must be. The former admin on this box mentioned "openmanage" array manager (or something like that). Is there a Linux equivalent of this program? and would this be what I need?
there is management software for the server (OMSA) and management software
for the array (dellmgr) but they are not integrated AFAIK.
> - What other 'gottcha' should I be fore-warned of?
have the latest firmware on your machine, esm, bios, raid
if you are configuring a raid5 array i highly recommend you consider
allocating a hot spare in the array.
