Can windows server be installed on a raid 5 array?

Will there be any problems having the OS and all my data on a RAID 5 array together, or is it better to have the OS on a separate drive?
 
Either way is fine, a lot of admins tend to separate the OS volume from the Application volume.

Personally, if they're not using separate arrays, there is no performance benefit. It is simply a manner of separating the OS and keeping the app elsewhere in the event of an OS failure (reload C and don't affect D).

In addition, I've been a bit annoyed with past admins who separate them, and only leave 10-12 GBs for the OS, and also install apps on C. There comes a time when the updates from MS cause the drive to reach full capacity, and then you play the what can/can't I move over to D to open up some space.

And, if you're using SQL, it is best to have an OS array, a Database array, and a Log array that use separate physical disks.

As for RAID5, we use it on ten to twenty systems at least here, so you should have absolutely 0 trouble so long as your RAID controller is supported.
 
Hardware RAID5? Yes. Software RAID5? Not unless they fixed that in Win2K8. It's good practice to have a separate array, usually a RAID1 volume, for the OS but it's not a hard requirement.

Amen brotha'. I have been plagued with this issue so far on five servers. I wanted to shove my foot up the ass of the previous admin. Fortunately for both him and my foot, he is no longer working here.

Same situation as far as the admin being long gone. Any chance I get to rebuild one of those, the OS partition either goes up to ~30GB, or it becomes one big drive depending on the software that's installed.
