Hybrid Host Connections
Hybrid systems feature two additional iSCSI ports that can be used for remote
replication or host LUN mapping.

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 and FC switch
(FC)
.
NOTE:
To gain optimum performance, make sure the LAN switch
(1)
for the management station
(2)
, the LAN switch for the systems, and the iSCSI switch
(3)
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.
