Relationship of WWPNs and iSCSI names for host objects

A host can be created with worldwide port names (WWPNs) or iSCSI names. The WWPN name space and the iSCSI name space within IBM Spectrum Virtualize™ share the same internal IBM Spectrum Virtualize resources.

The iSCSI name in a host object can take up to a maximum equivalent of four WWPNs depending on the number of I/O groups in which the host participates. This affects the maximum number of hosts that you can configure in a IBM Spectrum Virtualize clustered system.

Each IBM Spectrum Virtualize I/O group can have up to 256 iSCSI IQNs.
  • Creating an iSCSI host object with one iSCSI name in one I/O group is equivalent to creating a Fibre Channel host with one WWPN.
  • Creating an iSCSI host object with two iSCSI names in one I/O group is equivalent to creating a Fibre Channel host object with two WWPNs.
