You have enough for proof of concept then

What kind of array...

The installer procedure will guide you through but the disks must be
prepped for ASM. So must the OS itself. Or installer wont see the
Sounds like you aint read a dang thing yet alright. 18GB is plenty for the OS and Oracle after installation. I think that ASM work best as whole disks ....
Not much proof of concept going on with 2 sets of platters though. I guess something is better than nothing. Actually its not a bad little test box. But you should attach more disks at some point Received on Thu Jun 26 2008 - 00:16:03 CDT
