Hosts On An Ethernet Network; Device Configuration With One Host - HP StorageWorks D2D - Backup Systems User Manual

Hosts on an Ethernet network

Each emulated backup device is uniquely mapped to an individual host; this is the network server or
PC that you wish to back up.
• The backup device appears to the host as a locally-attached tape autoloader or library.
• The backup device is accessed and managed from the backup software running on the host.
• The backup device is not visible to other devices on the network.
• Multiple servers may not back up to a single backup device.
Figure 3 on page 23 shows a configuration with a single host. The Installation wizard has been run
on Host 1. The HP D2D Backup System automatically generates a library for the host. The user may
specify the number of slots during installation.
Figure 3 Device configuration with one host
• By default, only one device is visible to the host, the library that has been configured for it during
installation. Data from each host goes to its corresponding library.
• Each backup device is visible only to the host for which it has been configured.
• A host may have multiple devices configured for it on the HP D2D Backup System, but this means
fewer hosts may be connected (not illustrated).
Figure 4 on page 24 shows a configuration with three hosts. The HP D2D Backup System can be
used to back up a maximum of 24 hosts. The Installation wizard automatically generates a library
for each host. The user may specify the number of slots during installation.
