Brian,
We have seen the same thing, we are running out of CPU cycles and we continue to add capacity to our LSF pool. I am very familiar with the NetApp product but have no experience with the EMC but we are talking to them in a lot.
My understanding that, yes you could add Celerra processing power to the front end, but are you not still limited by the capacity of the data movers on the back end? One may point several Celerra processors to a file system but there is still only a single data mover to a volume. Please help me if I misunderstand the EMC configuration.

Might be a CPU limitation. Every single one of my Netapps willrun out of CPU cycles long before they run out of disk. A clustered pair of the F740's routinely burst over 10000 NFS ops/sec each, but they only need a couple shelves of 18GB drives between them. With an EMC Celerra, you can keep the same pool of drives, but plug in more front-end processors to soak up the NFS load. I believe they support up to 14 of those, sharing the same array of drives.
