Notes
The Remote Replication premium feature must be enabled and activated on the local and remote
storage arrays that will be used for replication activities.
You can use any combination of alphanumeric characters, hyphens, and underscores for the names.
Names can have a maximum of 30 characters.
The local and remote storage arrays must be connected through a Fibre Channel fabric or iSCSI
interface.
Passwords are stored on each storage array in a management domain. If a password was not
previously set, you do not need a password. The password can be any combination of a alphanumeric
characters with a maximum of 30 characters. (You can define a storage array password by using the
set storageArray command.)
Depending on your configuration, there is a maximum number of remote replication groups you can
create on a storage array.
Remote replication groups are created empty and replicated pairs are added to them later on. Only
replicated pairs can be added to a remote replication group. Each replicated pair is associated with
exactly one remote replication group.
The Remote Replication process is initiated at a defined synchronization interval. Periodic point-in-
time images are replicated as only the changed data is copied and not the entire virtual disk.
