Do not inter-link SAN storage with accessing a database from 2 FB servers running on 2 nodes/systems. SAN storage (NAS storage is different) is fine for use, we have used it in the past with no issues. But whether using local, SAN or NAS storage, a database file can only be accessed from a single server running FB. Sean
