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.
JBOD Connections
A SAS host link cable is included per JBOD. 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!
JBOD SAS Expansion Configuration
The SAS expansion port connects to expansion JBOD enclosures. For Dual Controller
systems, each expansion port connects a controller to a corresponding JBOD controller
making fault-tolerant links to different SAS domains.
The following principles apply to Unified Storage and JBOD connections:
•
Dual Controller Unified Storage System connects to Dual Controller JBODs.
•
Single Controller Unified Storage System connects to Single Controller JBODs.
