February 3, 2003 EMC CLARiiON Open Systems Configuration Guide SAN and Private 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 LAN free, SAN and private LAN topology, the backup server is connected through the SAN to EMC CLARiiON storage systems. Additionally, a separate, private LAN is implemented solely for the purposes of backing up clients not part of the SAN. In this configuration, SAN 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 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 private 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. Note: For Solaris PCI, Windows NT, Windows 2000 systems, AIX and HP-UX an additional FC HBA (in addition to the ones used for EMC CLARiiON attach) is not required for accessing the tape library. For Solaris SBus servers, an additional HBA is required for accessing the tape library. This HBA uses a different driver than the one used for the EMC CLARiiON storage system attach.

SAN and Private 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 LAN free, SAN and private LAN topology, the backup server is connected through the SAN to EMC CLARiiON
storage systems. Additionally, a separate, private LAN is implemented solely for the purposes of backing up clients
not part of the SAN. In this configuration, SAN 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 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 private 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
.
Note:
For Solaris PCI, Windows NT, Windows 2000 systems, AIX and HP-UX an additional FC HBA (in addition to the
ones used for EMC CLARiiON attach) is not required for accessing the tape library. For Solaris SBus servers, an
additional HBA is required for accessing the tape library. This HBA uses a different driver than the one used for the
EMC CLARiiON storage system attach.
