The performance of our file systems on SATA is quite acceptable.We have a storage pool on high performace drives.  We would like to use it for SAN.  It resides on two 4+1 RAID groups.  There is a WINNT file system on this storage pool. Is this one of the Celerra defaults?  If so, can it be moved?  Thanks...
