Radi Config
How would you configure your disks with those specifications?
General Database Characteristics:
os is Oracle Enterprise Linux 64 bit
Enterprise Edition
180GIG size database.
High "oltp" environment.
Estimated growth of 40 to 60GIG/year
20GIG of archivelogs/Day
Flashback time is 24 hours:120GIG of flashback space in avg
Local backup. Full database copy, then incremental is the preferred method.
That way, if a datafile goes bezerk, replace with backup datafile then recover.
Or if only a few corrupt block, block recover with rman.
BTW: Backup is done locally first, then send to another server, than on tape.
Archivelogs is duplexed on another server.
General Hardware Info:
Server Platform: Dell PowerEdge 1950
16 GIG RAM
2 * 64 bit CPU's
2 * local 300G/15rpm disks
Storage: Dell PowerVault MD3000
15 * 300G/15rpm Disks
Possibility for 17 disks here.
Here is my configuration so far:
OS+ oracle binary + Online Redo Logs Copy 1 + Control File Copy 1: 2 disks raid 1
flashback + backup + Online Redo Logs Copy 2 + Control File Copy 2: 4 disks raid 1 or 10
archivelogs: 2 disks raid 1
Temporary Datafiles: 1 disk no raid
UNDO Datafiles: 2 disks raid 1
Datafiles 6 disk raid10
total 17 disks: + spare disks on the side of one ever fails
1) How would you configure it with those specs?
2) Is there missing info to make a particular decision?

so you want to install OS and Oradle binary in a SAN?
if I was you I would just use SAME, Stripe All Mirror Everything, i.e RAID 10 for everything
be careful with Flashback, it has some overheads
