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 Storwize® V3700 share the same internal Storwize V3700 resources.

Each Storwize V3700 I/O group can have up to 512 WWPN entries. Each Storwize V3700 I/O group can have up to 256 iSCSI IQNs.
  • Creating an iSCSI host object with one iSCSI name is equivalent to creating a Fibre Channel host with one WWPN.
  • Creating an iSCSI host object with two iSCSI names is equivalent to creating a Fibre Channel host object with two WWPNs.
