Configuring Synchronous Long Distance Remote Copy
NOTE: HP 3PAR Remote Copy Software requires an HP 3PAR Remote Copy license. For more
information about the license, see the HP 3PAR OS Concepts Guide.
In an SLD Remote Copy configuration, a single Remote Copy group is copied directly to volumes
on two other systems by admitting the volumes to groups with two targets. Synchronous mode
Remote Copy is used between the primary (source) and backup system that are physically closer
to each other where a high bandwidth/low latency connection is shared. Asynchronous periodic
(periodic) Remote Copy is used between the primary system and backup system that are physically
farther apart and sharing a lesser connection. The synchronous connection must be a Fibre Channel
connection, while the asynchronous periodic connection can be either all Fibre Channel (over an
IP network) or all IP. Only unidirectional functionality is allowed between Remote Copy pairs.
NOTE: To configure SLD Remote Copy, you must have three available systems with configured
Remote Copy ports. At least two of the systems must have Fibre Channel ports.
To configure SLD Remote Copy:
1. In the Manager Pane, select Remote Copy.
2. In the Common Actions panel, select New Configuration.
The New Remote Copy Configuration wizard appears.
Targets
1. Under Select a Configuration, select Synchronous Long Distance.
2. Under Assign a System to Each Target:
• Select a storage system graphic. In the menu list, select a storage system to assign. Repeat
for the other storage system graphics.
NOTE: Only available systems, which satisfy requirements appear. For more information,
see the HP 3PAR Remote Copy Software User's Guide.
