VLS Settings
• SCSI Vendor ID Displays the ID automatically generated by the appliance. (Your backup software
might require this information.)
• SCSI Product ID Select the I D that you want to associate with the VL. (Your backup software
might require this information.)
• Compression If your backup software supports a hardware compression feature for use with tape,
you can use this option to emulate that feature. For optimal backup performance, leave this
check box cleared; to maximize the backup storage capacity, select this check box. This option
applies to all virtual-tape cartridges on the VL.
• Maximum Capacity per Tape Enter the maximum size (up to 2000 GB, depending on space
available) that you want to allow each virtual tape to reach.
• Drive Count Enter the number of virtual driv es that you want to allocate to the VL. Depending on
the
number of drives remaining, you can enter up to 4.
• Cartridge/Slot Count Enter the number of virtual tapes and corresponding slots that you want to
