RE: what is BAARF?

Title: Message

Interesting discussion.  this is the first time I have seen objections to RAID technology.  My cohort in crime, my senior developer (Lee Achorn), and I discussed this at length yesterday and without knowing the compelling arguments came to the conclusion that at least for a database system that maintains transaction logs (are these Redo logs for Oracle?) on off-server real estate and a good back up regimen is in place then why would one need RAID 5?

 

We are running RAID 5 here at MacDill and we have had 4 single disk failures in the last 14 months.  The rebuild time has essentially been 45 minutes to 90 minutes with degraded server operations.

It is good to see Oracle and Informix DBAs agree on something once in a while.
Art Kagel and many others from the Informix list have been fighting the good fight for a long time.

I sent this baarf link to a former co-worker still in the Informix world. I got this response:

Bob,

That is impeccable timing. I was in Dallas last week with Victor and James looking at SAN systems from Hitachi and IBM. Both vendors were heavily pushing RAID-5 and treated me like a leper when I objected.

Troy.

My question is what to do from a practical point of view. How have others approached convincing management that RAID 5 is the devil. I guess what I want is a list of the most effective questions and facts that will make these vendors look like idiots when they refuse to give up on RAID 5.
