•Discovery domains and login control service – Resources in a typical storage network are divided into manageable groups called discovery domains. Discovery domains help scale the storage network by reducing the number of unnecessary logins; each initiator only logins to a subset of targets which are within the domain. Each target can use Login Control to subordinate its access control policy to the iSNS server. Only initiators matching the required identification and authentication are allowed access by the target during session establishment.
•Open mapping of Fibre Channel and iSCSI devices – The iSNS database can store information about Fibre Channel and iSCSI devices and mappings between the two in a
When you start the storage system, the iSNS client on the storage system gathers all the
For information about setting the iSNS service in your iSCSI storage network, see your Microsoft and EMC documentation.

To configure iSNS client, login to Navisphere Express. For each iSNS server to which you want the storage system to connect:
1In the Manage iSCSI window, click iSNS.
2In the iSNS Servers window, click Add.
3In the Add iSNS Servers dialog box, enter the IP address of the cluster node you are adding.
4Click Apply to notify the SP iSCSI port information to the cluster node.
