Raid1
It is pretty good except for a little performance because of double wrtting.

Raid 5
It is good for DSS systems.

Even in this case, you should more disk at smaller disk sizes. This will allow you to have more RAID sets, so that you may spread Indexes and Datafiles and Rollbacks and Redo Logs and Control Files. You should at least have 2 Raid Sets to allow to use multi-plexing of Redo Logs and Control Files.

Also: no sense in spreading data across Raid 5 set to speed queries up if you only have 1 controller for 4 drive. Should have as many controller as you can.

Make sure that the hardware manufacturer has 'hot swap' capabilities. This allows you to take disk out when it damaged and the system should still be operational. Received on Sat Oct 11 1997 - 00:00:00 CDT
