Server Priority Manager Operati on 6-3
Hitachi Universal Storage Platform V/VM Hitachi Performance Manager User’s Guide
If One-to-One Connections Link HBAs and Ports Figure 6-1 shows an example of a network in which each host bus adapter is
connected to only one port on the storage system (Henceforth, this network is
referred to as network A). Host bus adapters and the storage system ports are
directly connected and are not connected via hubs and switches.

Figure 6-1 Network A (One-to-one Connections between HBAs and
Ports)
If one-to-one connections are established between HBAs and ports, take the
following major steps:
1. Set priority to ports on the storage system using the Port tab of the
Server Priority Manager window.
In network A, the ports 1A and 1C are connected to high-priority
production servers. The port 2A is connected to a low-priority development
server. Therefore, the ports 1A and 1C should be given high priority, and
the port 2A should be given low priority.
Figure 6-2 shows a portion of the Server Priority Manager window where
the abbreviation Prio. indicates that the associated port is given high
priority, and the abbreviation Non-Prio. indicates that the port is given low
priority.
Note: Throughout this manual, the term prioritized port is used to refer to
a high-priority port. The term non-prioritized port is used to refer to a low-
priority port.
