My mistake, it is 36 GB x 8 SCSI U320 10K HP, Part no 286713-B22 > I would suggest, if you have the cash, RHEL. This will work great for > Oracle. Guaranteed.

Redhat Enterprise Linux - AS (upto 16 CPUs & 64 GB Main memory) OR Redhat Enterprise Linux ES (upto 2 CPU & 8GB Main memory) I think we should get RHEL-AS ? recalling 4CPUs xenon 2.2 Ghz we have. > > Else, either Whitebox http://whiteboxlinux.org/ if you would like to stick > to Red Hat, or Debian http://www.debian.org Any success stories?, package updates ... > > Everyone is "performance hungry", for various value of "performance".

It is HP 6400 array controller with 192 MB cache. I have the smart start CDs But when i choose Linux as the OS(other options are windows 2000, windows 2003, Novel,OS/2, SCO etc) in ROM Based Setup Utility (RBSU) and then boots from smart start CD 7.0 it says :- "OS selected is not supported for assisted installation using smart start..." :( How do i configure array of hard disk for RAID?. I have hardware card for RAID system. let me check its no..
