Dell PowerVault MD3260i - Manual (Page 179)

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.
