Take a look at http://media.netapp.com/documents/tr-3801.pdf first before you add the PAM card to see if it will make a difference in your environment.

Hello,****
i'll try to improve our I/0 Perfomance. We have a raidgroup with 16 disks (SAS), 1 aggregate and 1 volume (dedup enabled). The volume is the storage for 100 VM's on the VMware Cluser (access via NFS). Does it make sense to increase the raidgroup? 90% Percent of the Disk I/O are Read Ops, so i'll buy a PAM Card for our FAS3240,too.****
And what's your Experience with the Raidgroupsize of a Raidgroup with SATA Disks (now: 11+1)?****
Thanks and greets !****
