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.
