Re: Database mirroring, again

I too have been following this with interest. Being paranoid, I mirror the
database twice - once in hardware and again in software, but I appreciate
this is a luxury not available to most.
I'm sorry but I fail to see the logic in not using battery-backed cache in
the RAID controller. If the cache is used for writes, then battery back-up
is an absolute must. Granted the uncommitted transactions can be rolled
back, but battery-backed write cache is the only way to guarantee
transactions that are committed actually hit the oxide.

Neil
