February 3, 2003 EMC CLARiiON Open Systems Configuration Guide SAN with Dedicated Tape Drives A dedicated tape drive is a drive within a library that is statically and permanently associated with one backup client. In a LAN free, SAN topology, the backup server is connected through the SAN to EMC CLARiiON storage systems. In this configuration, client backup data flows from the EMC CLARiiON storage system 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 system, 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.

SAN with Dedicated Tape Drives
A dedicated tape drive is a drive within a library that is statically and permanently associated with one backup client.
In a LAN free, SAN topology, the backup server is connected through the SAN to EMC CLARiiON storage systems. In
this configuration, client backup data flows from the EMC CLARiiON storage system 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 system, 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. For this topology, additional requirements are found in the associated table in the CLARiiON Backup Solutions
section of the
EMC Support Matrix
