Battery In RAID controller

Hello 
I have a DL380 Gen9 where the raid-controller (P440ar )battery needs to be replaced. The servers has inactivated the chache functionallity of the RAID card.

Thi is a verry vital server and we cant turn it down until next month.
Question:
-What risk are we taking?
The OS is running on RAID1 where the battery is out of order.
-Is it only degraded performance or are there other coinsiderations in case of a failed disk in the rad1 config?
-Is it possible to rebuild the one disk if its replaced when the cache function is out of order?

You will see low performance since the write cache is disabled.

You can even overwrite this at your own risk.


Hope this helps!

Yes
