filesystem size in RAID 5

we just got a PowerEdge 4600, dual 2.8 GHz, 2 X 73GB in RAID 1 (for the
system), and 8 X 73GB in RAID 5 (for fileserving). running linux 7.3 which
was preinstalled.

two questions:

1) is there any good reason to keep the linux preinstall? id really like
to just reinstall everything myself. i noticed that dell has a utility
partition. what is that? the RAID and BIOS utilities are not effected if i
blow away that partition, right?

2) concerning the RAID 5 array, the max ext3 filesystem size i can make on
it is 469GB, when the actual "disk" size should be 512GB (73GB X 4). is
this normal, or am i hitting some limit in linux? im assuming its normal,
maybe the journal is taking up a lot of space, but i just want to make

thanks in advance,
