This is something that popped right out for me. Do you have your storage pools 
located on raw logical volumes or mounted filesystems? If the latter, that 
might be your problem. Solaris has traditionally had incredibly poor throughput 
performance on mounted filesystems.

You might give thought to rebuilding those storage pools on raw logical 
volumes. Of course, that will require that you completely flush all data from 
your disk storage pools to tape storage pools first, so as not to lose client 
data.
