Utilizing Hybrid iSCSI Ports for Data Replication
The illustration above depicts the utilization of the iSCSI host ports for remote data replication.
This type of connection allows you to get the full benefits of high-speed FC host link,
management LAN connection, and robust link for data protection (volume copy/mirror).
Two hybrid systems, a source system and a target system, reside within the same virtual pool
but are physically apart. You can create a volume copy/mirror pair for data protection without
relying on slow management LAN cable connections. In such case, you can link the hybrid
systems using iSCSI host ports. If the distances between systems are far, additional switches
may be required.
Use PAC Management Software to configure the volume copy/mirror settings. PAC
Management Software automatically detects the iSCSI data connection for data replication.
Expansion Connections
When expanding your system, you can add expansion (JBOD) systems and connect between
devices via the SAS ports or the added SAS 12 G host board.
A SAS host link cable is bundled per expansion package. If you need to purchase other cables,
or if you need other cables of different lengths, contact your vendor.
Before configuring the expansions, you must take note of the following important points:
•
For a cleaner and clutter-free rack system, have carefully planned routing paths when
connecting between systems.
•
All SAS cables are sensitive and must be handled with care. DO NOT bend or twist
cables when connecting the systems installed to the rack.
