I'm affraid this is going to sound like a dumb question, but maybe not.  One of our HP servers is getting the error "Drive Array Accelerator Battery Failed, the array acceelerator attached to the array controller in slot 0 is reporting a battery failure"

How concerned do I need to be?

It'll hurt performance because if the battery is dead the write cache will be disabled. Apart from that there isn't any data loss risk because it will flush the cache and just use it for read caching. That's assuming it isn't a Px10 (latest models) which do allow you to set the cache enabled even if the battery fails (very unlikely you have one of them since their batteries won't be failing until a couple of years from now).

Is the battery easily replaceable on an HP DL360 G4

Easy to replace, it's in a black plastic package at the very front corner when you have the lid off. It's a cold replaced part so you have to power off to do it. I think you can disconnect the cable from the battery end rather than trace it back to the cache module which is under the PCI riser cage. Page 29 of http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c00687567/c00687567.pdf or there's probably a video on HP's site which you don't really need as it's straight forwards.

Oops, DL360, I read it as DL380. DL360 G4 page 38 0f http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00218204/c00218204.pdf, it's mounted on the cache module itself. Don't have the spare part number to hand I'm afraid.
