In our experience, it is very likely that your Fibre Channel hardware itself will fail long before one of the machines that rely on them. Seriously. We had so many RAID systems say goodbye, be it based on Firewire or FC...
What we finally arrived on is a serious NAS storage, like a NetApp FAS, plus multiple cheaper NAS RAIDs for backups and bulk storage. Using the network for file system access has the advantage of not introducing another channel that can bring your systems into failure. If your machines run fine on the network but the FC adapters or the FC switch fails, you're down. If the network fails, you're down with your service anyway. Plus, all machines can have the same file systems mounted simultaneously.
