Copy and Continentalclusters solutions. HP 3PAR Remote Copy is a product that allows you to copy virtual volumes from one 3PAR storage system to another.

Remote Copy Pairs

A Remote Copy pair is a pair of storage systems on which Remote Copy operations are performed. Within this pair, the 3PAR storage system from which the data is being replicated is the primary storage system. The 3PAR storage system to which the data is being replicated to is the remote or backup storage system.

Remote Copy Volume Groups

Remote Copy operations are performed on groups of virtual volumes called Remote Copy volume groups. Remote Copy ensures that the replication of data in the volumes within a Remote Copy volume group maintains write order consistency.

Remote Copy operations are started or stopped, for the whole group. When point-in-time snapshots of such volumes are created, writes to all volumes in the group are blocked to ensure a consistent point-in-time copy of the whole volume group. The set of volumes on the primary storage system to be copied is known as a primary volume group, and the set of copied volumes on the remote storage system is known as a secondary volume group.

Figure 54 shows a sample Remote Copy configuration.

In Figure 54, Array1 is the primary storage system for the Remote Copy volume group X and Array2 is the primary storage system for the Remote Copy volume group Y.
