Using Remote Replication With Other FeaturesRemote replication can be used with other disk utility features such as:• Storage Partitioning• Snapshot Virtual Disk Premium Feature• Virtual Disk Copy Premium Feature• Virtual Disk Expansion (VDE)Snapshot Virtual Disk and Virtual Disk Copy are premium features that must be enabled and activated on the primarystorage array.Storage Partitioning With Remote ReplicationStorage partitioning allows hosts to share access to virtual disks in a storage array. A storage partition is created whena collection of hosts (host group) or a single host is defined, then a virtual disk-to-logical unit number (LUN) mapping isdefined. This mapping allows you to define which host or host group has access to a particular virtual disk in the storagearray.Storage partition definitions for the local storage array and remote storage array are independent. Establishing similardefinitions on the disk serving in a secondary role reduces administrative effort required during site recovery.Snapshot Virtual Disk With Remote ReplicationA snapshot virtual disk is a point-in-time image of a virtual disk. In a remote replication, do not mount a snapshot virtualdisk on the same server as the primary virtual disk.Virtual Disk Copy With Remote ReplicationThe virtual disk copy premium feature copies data from a source virtual disk to a target virtual disk within the samestorage array.A primary virtual disk in a remote replication can be either a source virtual disk or a target virtual disk in a virtual diskcopy.You can create a virtual disk copy on the primary virtual disk in a replicated pair, but you cannot create a virtual diskcopy of a secondary virtual disk in a replicated pair. Instead, you can copy a secondary virtual disk in one of two ways:• Promote the secondary virtual disk to the primary role.CAUTION: If a primary/secondary role reversal is begun while a virtual disk copy is in progress, the virtualdisk copy fails and be unable to restart.• Create a snapshot virtual disk of the secondary virtual disk, then perform a virtual disk copy of the snapshotvirtual disk.Virtual Disk Expansion With Remote ReplicationVirtual Disk Expansion (VDE) increases the capacity of an existing virtual disk. This increased capacity is achieved byusing the free capacity available on one of the following:• The disk group of the standard virtual disk• The snapshot repository virtual disk133
