Non-disruptive Storage Migration

Non-disruptive Storage Migration
Non-disruptive Storage Migration is a function that migrates the volume data from an old storage
system to volumes in a new storage system without stopping a business server in cases such as
when replacing a storage system.
The connection interface between the migration source storage system (external storage system)
and the migration destination storage system (local storage system) is only the FC cable. In addi-
tion, the direct connection and switch connection topologies are supported.

Item
The maximum number of multipath connections between the local
storage system and the external storage system (per external stor-
age system)
The maximum number of ports in the external storage system that
can be connected from the local storage system (per FC-Initiator
port)
The maximum number of migration target volumes that can be im-
ported to the local storage system (*1)
The maximum number of migration target volumes in the external
storage system that can be imported simultaneously to the local
storage system
*1: The number of migration target volumes that are imported to the local storage system is add-
ed to the number of volumes in the local storage system.
Connect the external storage system to the local storage system ETERNUS DX using FC cables. Af-
ter the connection is established, add multipath connections between the local storage system and
the business server to prepare for the data migration.
