Yes we do, our whole data center runs from a room full of batteries which are powered by 2 big diesel generators. SO losing power is the least of our worries. We just want to assure that if the server fails, that the latest transactions logs are still going to be intact on the SANS disk and/or cache so we can retrieve them. The EMC CX600 does have dual battery backup for the controller.

We are planning to Deploy Quad-proc servers that are boot-to-SAN on an EMC Clarion CX600. The OS, Logs and DATA will be stored on the SAN. The problem is we are not sure if the transaction log data will be secure in the case of server outage, since the SAN utilizes a very hefty cache before it writes the data to SAN disk. We have already begun queuing our SAN vendor and MS, but they do take awhile in complex questions such as these, I was wondering if anyone in the list has deployed Exchange 200x on a SAN and has come across this question? Thanks again, Anthony L.
