I kinda like to spread my redo to several disks I have 4 disks and i write the redo logs as follows Disk1 - OS G01_M1 on disk2 G01_M2 on disk3 G02_M1 on disk3 G02_M2 on disk4 G03_M1 on disk4 G03_M2 on disk2 and so on this way redo is safe from disk failure. -- Mir M.

From: "dave" <david.best@xxxxxxxxx> Date: 08-04-2009 07:49 Hey all, If you had 8 disks in a server what would you do? From watching this list I can see alot of people using RAID 5 but i'm wary of the performance implicatons. (http://www.miracleas.com/BAARF/) I was thinking maybe RAID 5 (3 disks) for the OS, software and backups. RAID 10 (4 disks + 1 hot spare) for the database files. Any thoughts? -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
