iSNS: What Does It Provide?

Scalable information facility for registration, discovery and

management of networked storage assets

Unified Service Framework for Topology Discovery

– iSCSI, iFCP, and extensible to FCIP and other IP storage protocols – Integrates with DNS infrastructure

Zoning: iSNS maintains access control policy for

registered targets and initiators

Asynchronous notification of Zoning and Topology

changes

Lightweight protocol deployable in servers, switches, and

targets

Why is iSNS Needed?

Consolidate registration, discovery and management of

storage assets

– Simplify storage management implementation – Improve scalability compared to broadcast/multicast discovery methods

Enable secure IP storage “Zoning” capability

– Allow crypto key distribution for iSCSI login authentication

Dynamic tunnel endpoint discovery (FCIP only)

Incorporate requirements and recommendations from

iSCSI Naming and Discovery team

Extend to include tunnel endpoint discovery for FCIP
Evolve with iFCP specification
Adopt iSNS as official IPS WG item
