Creating a Remote Storage Center Connection
Creating a Remote Storage Center Connection
Once a local (source) system is connected to a remote (target) system and the remote
system is connected back to the local system, you can replicate volumes from an Initiator
to a Target.
Note Storage Center automatically detects a Storage Center system connected via FC.
Once recognized, remote FC systems appears in the System Tree.
iSCSI Remote Connections
iSCSI facilitates data transfers over IP networks. Unlike FC, which requires special-purpose
cabling, iSCSI can be run over long distances using an existing IP network infrastructure.
A Remote Storage Center Connection connects an iSCSI port on one Storage Center to an
iSCSI port on another Storage Center.
Note In the following text, card is synonymous with port.
• In Virtual Port mode, Remote Storage Center Connections are added to the Control Port
of the Fault Domain that is being connected. When both systems are running in Virtual
Port mode, connect the Control Ports of the Fault Domains.
• In non-Virtual Port mode, the Remote Storage Center Connections are added to each
individual iSCSI IO Card. When both systems are running in non-Virtual Port mode,
connect each iSCSI IO Card from each system to all IO Cards on the other system (and
vice versa).
• In a mixed mode, when one system is running Virtual Port mode and the other is running
non-Virtual Port mode, connect the Control Port to each individual IO Card from the non-
Virtual Port mode system; connect the IO Cards from the non-Virtual Port system to the
Control Port.
