The above diagram demonstrates how to utilize the iSCSI host ports for remote data
replication.
The two hybrid systems, a source system
(1)
and a target system
(2)
reside within the
same virtual pool but are physically apart. You want to create a volume copy/mirror
pair for data protection, but do not want to rely on slow management LAN cable
connections. In such case, you may link the hybrid systems using iSCSI host ports. If
the distances between the enclosures are far, additional iSCSI switches
(3)
might be
required in between.
The illustration above demonstrates how you can enjoy the full benefits of high-speed
FC host link and management LAN connection, as well as a robust link for data
protection (volume copy/mirror).
The SANWatch software suite, on which you configure the volume copy/mirror settings,
will automatically detect the iSCSI data connection and will use it for data replication.
