iSNS Internet Storage Name Service draft-tseng-isns-01.txt Josh Tseng Technology Consultant Nishan Systems jtseng@nishansystems.com
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
Unified Discovery & Management Framework iSCSI iSCSI Device Device IP Network iSCSI Device Management Platform iSNS FC iFCP iFCP FC Device Gateway Gateway Device FCIP Gateway FC FC Device Device FC FC FC Device Device SAN
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)
Next Steps • Draft found at: – www.ietf.org/internet-drafts/draft-tseng-ips-isns-01.txt • Incorporate requirements and recommendations from iSCSI Naming and Discovery team • Extend to include tunnel endpoint discovery for FCIP • Evolve with iFCP specification Action Request: • Adopt iSNS as official IPS WG item
