Just my 2c:
1) if you're running a software RAID this size, why wouldn't you want to
RAID-1 your Boot disk? A single disk failure of the boot disk will make
your raid5 unavailable until you can get your distro restored from tape
along with the latest LVM/MD configuration (you had that saved somewhere,
2) If you're running a software raid this size, maybe you should consider
the Synology enterprise appliances (The Ds3612xs comes to mind). It does
more than a 'normal' distro for file sharing and usually come with enough
drive bays to provide expandability for the future. They're also less
costly than similar serveur hardware.
I run each of these setups myself :
- a T410 with 128Gb Ram, 6*3.5disks (2*2gb for boot and 4*3gb for data)
with an LSI MegaRAID SAS 9271-8i (full H/W Raid on the box).
- a DS3611xs with 8*2Gb disks in a two disk parity Syno Hybrid RAID.
Each of these provide nice performance (up to 300-400 Mb/s) and availabily
but I feel a little more secured on my Dell since its hardware RAID is software independant
My 2c, really.

They cannot scare me with their empty spaces
Between stars - on stars where no human race is
I have it in me so much nearer home
To scare myself with my own desert places. - Robert Frost
