1.3 Functions
• Host Affinity function
The Host Affinity function sets the "Host Affinity Group" to be applied for each server. "Host Affinity
Group" defines the relationship between the host logical units (LUN) and the device logical volumes.
Multiple settings are available.
Host Affinity function uses WorldWideName (WWN) or iSCSI name for the Fibre Channel card in the
server to recognize the server.
Figure 1.18 Host Affinity function
When multiple servers access the device using the same port, this allows corresponding different
LUNs and volumes per server.
