HP D2D User Manual

Replication-Target libraries are not visible to the host, unless you configure devices to make it
visible. See the HP StoreOnce Backup System user guide for more information.
Once you have set up a replication configuration between Source and Target HP StoreOnce Backup
Systems, it is initiated automatically whenever a cartridge is returned from a drive to a slot that
has been configured for replication.
Preparing for replication
There are 5 major considerations:
• Make sure you understand the basic concepts and terminology.
• Decide which deployment model is appropriate for your organization.
• Map your replication workflow and decide how the first backup will be seeded onto the target
appliance.
• Configure and monitor replication on the Web Management Interface
• Define your Disaster Recovery strategy if the Source Appliance fails.
Replication and firewalls
If replication needs to take place through a firewall, the network administrator will need to open
(TCP) ports 9387 (Command protocol) and 9388 (Data protocol) to allow the replication traffic
to pass to and from the HP StoreOnce Backup Systems. If necessary and the D2Ds conflict with
another device on the network, these ports can be changed from the defaults when you create the
replication pairing or from the Local Appliance's General Settings page.
Restricting access to replication sources
Source Appliance Permissions are disabled by default. In this state, there is no control over mapping
between share and library devices on the Target and the Source Appliances.
However, it is possible to lock down the ability to create share and library mappings so that, when
the wizard is run and mappings are configured, the Target only has access to a list of sources that
are allowed to replicate to it. See the HP StoreOnce Backup System user guide for details.
HP StorageWorks Replication Manager (HP D2D4xxx Series only)
HP StorageWorks D2D Replication Manager (D2D Replication Manager) is a standalone software
application that is available as part of the D2D Replication license with HP D2D4xxx Backup
Systems. D2D Replication Manager provides basic management capabilities in a replication
environment, and provides an easy way to manage up to 300 D2D devices that are being replicated
across multiple sites. Using D2D Replication Manager, administrators create, manage, and remove
groups of devices; and establish and control user and administrator access to the groups and
devices. D2D Replication Manager allows administrators and users to review the status of the
groups and devices to which they have access, either to ensure that replication is happening
successfully and on schedule, or to respond when there are replication operation errors. D2D
Replication Manager also provides the ability to monitor disk usage and deduplication ratios for
the devices. This allows administrators the ability to identify devices that may need additional
capacity. Trend analysis is also available to look at disk capacity changes that occur on devices
over a pre-determined period.
