I know this is not exactly the RAID 5 Best practices but this is how I
usually setup and recommend the customers to setup their disks (if they
can afford the hardware)
RAID1 for the OS
RAID1 for the logs
RAID0+1 for the database

Thanks, Brian. That makes sense.
So if I have a 4 disk array on a single backplane, and given that I
want the benefits of RAID 5, is there any argument for configuring
more than one partition on the array? I realize that this is
potentially too much of an open-ended question, but I'm curious :-).
The basic premise is that this server would be a workhorse domain
member/file server. Would one partition - C: - combined with carefully
configured share and NTFS permissions provide adequate security? Or is
it better to put the OS on C: and the shares on D: ? Or does the
benefit of partitions lie somewhere else - for example, if I wanted to
wipe C: and reinstall the OS without touching D: ? (I'm not sure if I
like this idea, but as I mentioned, I'm curious...).
Thanks,
Tim

Tim-
It doesn’t really matter. The RAID controller has no idea about the
partition table. It just presents a LUN to the OS and the OS writes to it.

Using a RAID controller's configuration utility I can build and
initialize a RAID 5 container. When installing the OS, I can, if I
choose, create a partition. Is this a good or bad idea? In other
words, if I partition RAID 5 container during the OS install will it
make any difference if I ever need to replace a drive and rebuild the
array? Will the partition table be recognized during the rebuild?
Thanks for your input.
