They will sell you the moon if you want, but let me give you
some practical advice. You seem like you are running your own
consulting business, so this advice will not only save you
time, but money which is key when running your own business.
Buy your computers with NO hardware RAID, your not setting
up high performance database systems for hundreds of users
here. Get systems with 2 identical internal 250GB SATA
drives and setup software RAID1 on them. Get an external
USB/Firewire drive, you can even get those in RAID1 too
and have automated dump scripts backup your data to it.
Install your Linux distro with common reproduceable options
using standard repos and document it.
Here's how I would setup the internal hard drives, can be
done easily through anaconda even with kickstart.
/dev/sda1 - 100MB RAID
/dev/sda2 - Rest of Disk RAID
/dev/sdb1 - 100MB RAID
/dev/sdb2 - Rest of Disk RAID
/dev/md0 - /dev/sda1 /dev/sdb1 RAID1, ext3, /boot
/dev/md1 - /dev/sda2 /dev/sdb2 RAID1, LVM
VG CentOS - PV /dev/md1
LV root - VG CentOS, 16GB, ext3, /
LV swap - VG CentOS, 4GB, swap
LV home - VG CentOS, 32GB, ext3, /home
LV work - VG CentOS, 64GB, ext3, /work
If the system crashes you can move your USB drive over to
the other system and restore there, and/or have rsync keep
the other system identical to the first. Setup NIS/NFS or
whatever to share the data/authentication information.
This setup will be more cost effective and faster then
what you are currently planning.
