I am in the process of allocating drive space in several new servers.
Each of these servers are to house DB's of some sort. Each has 6 X 146
gig drives and each will run RHES4. I was thinking of 2 arrays:
1 - mirrored pair of 146's for OS
1 - Raid 5 array with 4 x 146 for db's. That would give me a disk of
about 440 GB.
Currently, the biggest DB is about 30 GB. I figure there are just too
many ways that I can slice and dice it. Any advice appreciated.
Thanks.

I'd go with level 5 for the extra space. Fault tolerance is the same:
just 1 broken disk per "session" :) .
A four disk RAID 10 set can lose up to two drives without failing as
long as both are not in the same mirror set. RAID 10 has much better
read and write performance than RAID 5. Should a drive fail, rebuilds to
the replacement drive are faster making the window for a catastrophic
failure less.
