We're building a bunch of new servers (as I mentioned in another thread). What do you guys think is the best drive layout? Traditionally we just have the entire 4-6 drives in a RAID 5, but now I'm wondering if it makes sense to have a separate OS drive, and then the rest in a raid 5?
On a side note, we need a giant ~2TB-3TB partition on these boxes, that's why we go with the multi-drive raid setup. Thoughts? I know it was customary to have a separate OS drive back in the day (I remember having WD raptor's for that), but now when the WD Black-edition (which we'll be using for the raid setup) are as fast as the raptor's, is it even worth it?
Can you share some more details on what exactly you'll be storing/retrieving? If based on your signature, then I presume images?
You might consider building a NAS/SAN with OpenSolaris and ZFS(or insert other home grown storage box flavor here) for central storage rather than relying on 4-6 drives in each server. The rebuild time on a large failed drive with that few spindles will be painful to say the least. The read performance in your particular RAID 5 scenario is going to drop significantly during a disk rebuild.
