so that it cannot overrun the HP 3PAR Storage System port's queues when all host servers are
delivering their maximum number of I/O requests.
NOTE: When host server ports can access multiple targets on fabric zones, the assigned target
number assigned by the host driver for each discovered target can change when the host server
is booted and some targets are not present in the zone. This situation may change the device node
access point for devices during a host server reboot. This issue can occur with any fabric-connected
storage, and is not specific to the HP 3PAR Storage System.

Configuration Diagrams for Zoning

This section describes various zoning configurations.
NOTE: In the examples in the following sections, a fabric can be one or more Fibre Channel
switches or directors.

Single Initiator to Single Target Zoning No Fan-In No Fan-Out

With a single initiator to single target zoning, in a no fan-in, no fan-out configuration, each HBA
port is connected to only one HP 3PAR Storage System port, as shown in
Figure 1 Single Initiator to Single Target Zoning No Fan-In/No Fan-Out
Single Initiator to Single Target Zoning with Fan-Out from One HP 3PAR Storage System Port to
Multiple Host Server Ports
With single initiator to single target zoning, in a fan-out configuration, the HP 3PAR Storage System
port is connected to more that one host port, as shown in
Figure 1 (page
