In the process of commissioning a new server and thought I'd see what everyone thought of this configuration.
The server will be used to host a 1 reasonably large OLTP database at around 40GB and several smaller ones <2gb. The main DB is fairly heavy on both reads and writes.
My questions are
1. am I losing anything by going RAID1+0 on the data and log vol for the main database?
2. would I be better off using with just either the data of log from the main db on the RAID1+0, and placing the tlog and random back ups on the other RAID vol?
3. Ditch RAID1+0 entirely and have a separate vols for the radom db's log and data files.
The random db's are largely web apps with little writes here and there, fair bit of reading, but nothing huge.
