Lee,

  I think the consensus is to use Raid 0+1. Our sysadmin claims that our disk cache is so large, that it doesn't really matter that we are using Raid 5 (we are on Tru64 4.0d). I really don't have the hardware expertise or the time to prove otherwise. I wouldn't mind hearing some comments on that statement from other folks on the list as they reply to your question. I am able to flood the cache during sqlloader runs, but other that that, he seems to be correct.

All,

I have seen various threads on the subject of Oracle and Raid but don't have any messages stored on the subject so forgive me for the repetition factor.

Can someone provide a list of do's/don'ts, advantages/disadvantages of using various raid levels with Oracle (in this case 8) on a TRU64 4.0 platform. Database will be approx. 4Tb in size/

Regards

Lee
