Hybrid-Host Connections
For hybrid systems that feature two additional iSCSI ports, you can use these systems for
remote replication or for host LUN mapping.
Single Hybrid Unit Connected to FC/iSCSI Hosts
When connected to FC and iSCSI hosts, the connections are working in their respective
speeds. This connection maximizes the number of connections while keeping the optimum
performance gained by the high-speed FC link and FC switch.
NOTES:
•
To gain optimum performance, ensure that 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.
•
If they are not separated, the host may consider that the iSCSI connection is a part of the
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 slows down to iSCSI connection’s level
and the fast FC connection bandwidth may be spent without use.
