Topic: battery on raid card
I'm researching raid cards for a postgres server and have noticed that some have a battery backup.
if the power goes out; is that little battery going to spin all 8 drives to finish writing?
or does it hold the memory till the system boots again?
All I could find where high level answers such as:
"In the event of a power failure the RAID Card will automatically switch over to the battery back-up and complete any unfinished tasks."
