Utilizing Hybrid iSCSI ports for Data Replication
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 PAC Management 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.
Expansion Enclosure Connections
A SAS host link cable is included per expansion enclosure. You can also use one SAS 12G host board
for expansion enclosure in order to connect to more expansion enclosures and support more disk
drives.
If you need to purchase other cables or if you need other cable(s) of different length, please contact
your vendor.
WARNING
All SAS cables are sensitive and must be handled with care. To prevent interference within a rack
system, the cable routing path must be carefully planned and the cables
must not be bent.
Please contact your vendor for a list of compatible components.
