Hybrid Host Connections
For hybrid systems that feature two additional iSCSI ports, they can be used for
remote replication or be used for host LUN mapping if users wish to do so.
3.5.1
Single Hybrid Unit Connected to FC/iSCSI Hosts
When connected to both FC host and iSCSI host, the connections will work in
their respective speeds. It maximizes the number of connections while
keeping the optimum performance gained by the high speed FC link.
NOTE:
To gain optimum performance, make sure the LAN switch for the
management station, the LAN switch for the subsystems, and the
iSCSI switch for iSCSI host link are separated.
Otherwise, the host might consider the iSCSI connection as part of
host connection and might use it for data I/O, even if the iSCSI ports
are not mapped to the host. As a result, the data transaction speed
will slow down to the level of iSCSI connection and the fast FC
connection bandwidth will be wasted.
