Configuring Synchronous Long Distance Remote Copy
NOTE: HP 3PAR Remote Copy Software requires an HP 3PAR Remote Copy license. For additional
information about the license, see the HP 3PAR OS Concepts Guide.
In a Synchronous Long Distance 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: In order to configure Synchronous Long Distance 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 Synchronous Long Distance Remote Copy:
1.
In the Manager Pane, click Remote Copy.
2. In the Common Actions panel, click New Configuration.
The New Remote Copy Configuration wizard appears.
Targets
1. Under Select a Configuration, click Synchronous Long Distance.
