I assume this is 8 x 36GB SCSI. LC? LW?

I would suggest, if you have the cash, RHEL. This will work great for Oracle. Guaranteed. If your database is really important to your company, this is good value for the money. You get really great support. Else, either Whitebox http://whiteboxlinux.org/ if you would like to stick to Red Hat, or Debian http://www.debian.org > Our application needs a lot of Database I/Os , So basically we are DB > performance hungry what kind of RAID system we should implement, RAID > 5 ? Everyone is "performance hungry", for various value of "performance". What do you really need? Performance in terms of speed, or reliability? Firstly, apart from RAID 0, any other RAID MUST (I mean MUST) be: implemented purely (yes, purely) in hardware have a large RAM cache (512M? at least 256M) have a battery backup, on the "RAID card", at least 96 hours (think: long weekend) Anything else is at best useless, at worst snake oil. Next, if you can lay your databases/indices decently, the bulk of your work is done. A good DBA will out-perform a team of Sys Adms any day in database performance. How IO intensive is your app anyway? If really high, go to 15k drives, U320 (although U160 are not much worse). This is a quick win. Look for 8MB caches, on-drive. Buy good SCSI cables. The fastes way to improve HDD IO, in my view, is to stick in few G of RAM into the box. Amazing what caching will do. Split your drives into 3 groups: A RAID 5 set, or RAID 10, for your data A RAID 1 set, for the OS + App A normal disk, for swap + /tmp (who cares if you lose this?) bonnie++ is your friend. http://www.coker.com.au/bonnie++/ And for RAID any higher than 1, you need a storage array. You cannot just pop-in disks into your cabinet and leave it at that, read up on "spindle synchronization" if you want to do RAID 3. The drives you have may not support this. If you do realise you need faster drives, you know who to call :-) -- Sanjeev "ghane" Gupta _______________________________________________ ilugd mailinglist -- [EMAIL PROTECTED] http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/[EMAIL PROTECTED]/
