Thanks all for your inputs. Our current local drives are in RAID 5. The disk speed of SAN is 15K fiber or could be higher. The connectivity to SAN is via dedicated 2 GB fiber with failover.

        Did anyone migrated database from local file system to SAN, is the performance much better?          

As Mathias stated, it really depends on what you are going from and to.

If the db server has 5 IDE disks in a RAID 5, and you then move the storage to a high end SAN, and your connectivity is via 1Gb ethernet, it will probably be faster on the SAN.

You can't make a comparison without details.
