ISO/IEC 24775-6:2021

Overview - ISO/IEC 24775-6:2021 (Storage management - Part 6: Fabric)

ISO/IEC 24775-6:2021 specifies management profiles for storage networking fabric components as part of the Storage Management Technical Specification. Prepared by SNIA and adopted under JTC 1, this part defines autonomous profiles that model and control the behavior of storage networks and their devices. The standard focuses on the management view - topology, zoning, device state and status, control interfaces and product information - to enable interoperable, multi-vendor SAN management.

Key topics and technical requirements

• Profiles covered: Fabric, Switch, Extender - each defines a management model and required functions for its class of device.
  • Fabric Profile: models storage network topology and zoning control.
  • Switch Profile: models Fibre Channel switch state, status, port connections and product information.
  • Extender Profile: models devices that extend Fibre Channel over other networks (notably FCIP/IP-based extension).
• Management interfaces and modeling: aligned with SMI-S/CIM-based models (CIM-XML representations referenced in the specification).
• Interoperability rules: versioning and change control are defined (major/minor/update) to preserve backward compatibility between implementations.
• Maturity levels: Experimental, Implemented, Stable, Finalized - used to indicate implementation readiness and expected vendor support.
• Related elements referenced: DMTF Indications profile and other SNIA SMI-S constructs are integrated as normative or informative references.

Practical applications - who uses this standard

• Storage vendors and switch manufacturers implementing management agents and firmware for Fibre Channel switches, SAN fabrics, and extender devices.
• SAN architects and network/storage engineers deploying interoperable, multi-vendor SANs who need consistent topology discovery, zoning management, and device control.
• Management software developers and systems integrators building SMI-S/CIM-compliant tools for monitoring, provisioning and automating SAN operations.
• Test labs and service providers validating multi-vendor interoperability, zoning policies and FCIP/extension behavior.

Benefits

• Promotes consistent, vendor-neutral models for fabric management and zoning control.
• Facilitates automation and integration of SAN management tools via SMI-S/CIM.
• Clarifies compatibility expectations through explicit versioning and maturity levels.
