iSCSI

On an Ethernet network the HP D2D Backup System is con

gured as an iSCSI device. This

means that the HP D2D Backup System plugs directly into the network, but it presents devices as

directly-attached SCSI autoloaders to host machines. In order to function, it requires an iSCSI initiator.

On Windows systems, this is normally downloaded by the Installation wizard, as described in

“

Connecting and installing the HP D2D Backup System

” on page 27. For more information about iSCSI,

see “

Advanced installation

” on page 45. Linux and UNIX users should also refer to the “Linux and UNIX

Con

guration Guide” on the HP StorageWorks D2D Backup System CD-ROM for more information.

Libraries

A tape library is a backup device that has multiple drives and multiple storage slots. Each storage slot

contains a cartridge. The difference between an autoloader and a library is that a library can support

multiple tape drives whereas an autoloader only has one tape drive. This provides considerable storage

capacity and full support for tape rotation strategies. (It may be necessary to upgrade your backup

application to support libraries.)

Mail slots (import/export elements)

A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used speci

cally to

import and export cartridges. They are sometimes called import/export elements by backup applications.

Backup applications that support this feature move cartridges from the mail slot when the user runs an

Export job, and look for cartridges in the mail slot when the user runs an Import job.

Physical tape drives

A physical tape drive is a tape drive that is attached to the HP D2D Backup System or the host computer,

so that data can be moved from the HP D2D Backup System and stored offsite. (It should not be confused

with the tape drive device that is attached to the library device on the HP D2D Backup System (see

“

Devices (Con

guration)

” on page 90.)
