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 Lenovo Storage V series share the same internal Lenovo Storage V series 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 Lenovo Storage V series clustered system.

Each Lenovo Storage V series I/O group can have up to 512 WWPN entries. Each Lenovo Storage V series 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.
