We got a lot of value out of ours in an academic research context but switched around 2002 when they just couldn't manage to be price-competitive. We ended up with Spinnaker, Isilon, and NetApp boxes which were all Linux-based, although with some custom extensions (if memory serves, we found a bunch of correctness issues running fsx against Isilon because their filesystem implementation wasn't as robust as the stock Linux filesystems).
