SAN and LAN with Shared Tape Drives
A shared tape drive is a drive within a library that is dynamically and temporarily associated with a backup client. An
option module is usually required from the backup software supplier to implement shared tape drives.
In a SAN and LAN topology, the backup server is connected through the SAN to EMC CLARiiON storage systems. In
this configuration, SAN client backup data flows from the EMC CLARiiON storage systems through the SAN into the
clients, and then back out through the SAN, through a Fibre-Channel-to-SCSI bridge, and out to the tape library.
Backup data owned by the backup server flows from the EMC CLARiiON storage systems through the SAN into the
Backup Server, and then back out through the SAN, through a Fibre-Channel-to-SCSI bridge, and out to the tape
library. LAN client backup data flows from the EMC CLARiiON storage systems into the client servers across the LAN
to the backup server, out through the SAN, through a Fibre-Channel-to SCSI bridge, and out to the tape library. For this
topology, additional requirements are found in the associated table in the CLARiiON Backup Solutions section of the
EMC Support Matrix
