By using the host affinity function, a host interface port can be shared by multiple servers in a cluster system
or in a system in which servers with different OSes exist together.
• When using an FC switch, an FCoE switch, or a SAS switch, perform zoning settings for each switch. For
details on zone settings, refer to "User's Guide -Server Connection-" or the manual that is provided with
the switch.
• When using a LAN switch for iSCSI connections, use a LAN switch that has the VLAN function and allocate
a separate segment to each server.
For details on settings, refer to "User's Guide -Server Connection-" or the manual that is provided with the
LAN switch.
