UPSs all the way. With high random writes you'll get alot of buffering so even if you have a BBU for the raid, the data might still be in RAM.
the order of shutdown is important too, should really be
1) consumers of storage (within the first minute or so)
2) storage (about 15 minutes after)
if your network wobbles or the storage turns off too fast, everything hangs, and your in poostain pants town.
Ideally your DNS/AD shouldn't ever willingly shutdown. or if it does it should be well after the last bit of your production system has turned off.
