Configuring Synchronous Long Distance
Remote Copy
Note: 3PAR Remote Copy requires a 3PAR Remote Copy license. For
additional information about the license, see the 3PAR InForm OS Concepts
Guide.
In a Synchronous Long Distance Remote Copy configuration, a single Remote Copy group is
copied directly to volumes on two other InServ Storage Servers by admitting the volumes to
groups with two targets. Synchronous mode Remote Copy is used between the primary
(source) and backup server 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 server and backup server that are physically farther apart
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 InServ Storage servers with configured Remote
Copy ports. At least two of the servers 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.
Step 1. Targets
1. Under Select a Topology, click Synchronous Long Distance.
2. Under Assign Systems:
a. Click a storage server graphic. In the menu that appears, select a storage server to
assign. Repeat for the other storage server graphics.
Note: Only available InServ Storage Servers, which satisfy requirements
appear. See the 3PAR Remote Copy User's Guide for additional information.
3. (Optional) Under Update System's Location, enter a location for each storage server,
e.g. Lab 1, New York.
