Rouge volumes causing filer to drop off the network? Any help appreciated.

We have outgrown our 2050 and I have concerns with the sizing of the replacement.   We have two  aggregates' of sas  drives that produce 3000+ iops each.  The filer drops of the network at 1000 iops and the processor is constantly at 100%.  cp stats show that it is constantly flushing.  The network is never above 50 mbits/sec.  I have previously had 6000+ iops from using iometer from several windows servers with multiple threads.  The processor maxes when certain volumes are being heavily used.  When I look at the iops of one of the offending volumes there are little read or writes, but 95% of the iops are listed as nfs_other.   Also these volumes have massive inodes of 7-9 million and we are having to increase these as time goes on.  Does anyone know why these particular volumes are killing our filer and if we upgrade how do we know the next filer won't display the same problem?  Any comments or suggestions would be appreciated.
