As of right now we've been using a FC IBM DS400 that we replaced when we moved to VMware that housed our backups. Well the DS400 is starting to slow way down, and the support for it is next to none. I'm trying to find a semi inexpensive repalcement for it to store our bulk backups on. We have a IOmega ix4-200d in our R/D that I'm going to test out to see how that works but was looking for other recommendations on storage solutions. It doesn't have to be much, maybe 2TB?
Build your own and use Openfiler! The other IOmega devices are tempting too, since they are on the HCL.
