Home -> Community -> Mailing Lists -> Oracle-L -> RE: Write caching controllers
Brian,
I would not worry about it. To preclude any chance of data loss requires not having any data to loose in the first place.
I lost files using EMC Symmetrix, yet I have bought more.

Good morning all!
I have a question regarding use of write-caching RAID controllers.
As an NT systems/network admin of some years, and an Oracle 8i DBA-in-training, I had done some homework and gather that both Oracle and industry best-practices suggest avoiding write-caching controllers if possible (to preclude any chance of data loss).
As a result, I had recommended we purchase dual non-caching controllers on the new Compaq ML530s we are about to buy.
Compaq has discontinued the model controller we requested, and now all their controllers include write caching (battery-backed, of course).
We are running a couple of ~10GB instances, not terabyte OLTP - so should I just go with it and not be so anal about the caching??
Thanks and Regards,
Brian
