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. 196 Configuring and Managing Remote Copy
