One path to all
of your data,
everywhere.
Single Namespace is an open standard that gives every file, object, and dataset a single canonical address — resolved transparently across file systems, object stores, HPC, and multi-cloud, with no data migration.
// one canonical path — resolved transparently across every backend
Fragmented data is one of computing's most persistent problems.
Research, healthcare, and AI workloads increasingly demand exascale datasets — yet that data is scattered across incompatible systems with no common way to reach it.
Data is fragmented by design
Datasets live in incompatible silos across HPC scratch, object stores, and a dozen cloud regions — each with its own access path.
Migration is the only answer
Moving data between vendor platforms is slow, expensive and risky, and it has to be repeated every time a workload moves.
Stewardship breaks down
Silos make governance, provenance, and compliance nearly impossible to maintain consistently at scale.
Cross-compatibility across the entire storage ecosystem.
By standardizing four layers, the specification lets vendors build interoperable solutions where components can be swapped without migrating a single byte.
Interactions & Protocols
Standardize how clients and storage systems communicate across tiers, regions, and vendors.
Formats & Behaviors
Define consistent data formats and expected behaviors so components become interchangeable.
APIs & Interfaces
Publish open, royalty-free APIs that let vendors build interoperable, swappable solutions.
Cross-platform Access
Reach data from HPC to cloud through one namespace — with no migration required.
Two ways to participate.
SNS Working Group
The Single Name Space Technical Committee develops the open compatibility standard. Open to storage vendors, cloud providers, HPC manufacturers, and research institutions.
