Hi, I spend some time looking through the archives for any content focused on the impact of sharing a SAN across different applications, but didn't find any. We currently have an EMC SAN which serves production databases only. They (management) are now beginning to push for more storage for file sharing and I am sure mail will follow shortly and they want to put it all on the current EMC SAN. Does anybody have any experience they care to share on the impact of putting mixed content on a SAN and how that may or may not affect database performance.
