Single NamespaceAn OASIS Open Standard
SNUGOASIS Open · Vendor-Neutral

The community advancing single namespace interoperability.

SNUG brings together HPC practitioners, storage engineers, cloud architects, and vendors to define, implement, and evolve the single namespace standard across on-premises, cloud, and hybrid environments.

“Once everything is everywhere, anything can be run anywhere.”

01Why a single namespace
01

Unified data access

One consistent path across clouds, HPC, and edge. No rewrites when compute moves.

02

Reduced storage costs

Local storage becomes a cache. Petabytes live in object stores at cold-tier pricing.

03

Workload portability

Run on any cloud or HPC. Infrastructure becomes a business decision, not a constraint.

04

Built-in resilience

Replicated object stores behind one stub. A provider fails — the orchestrator reroutes.

05

Data governance

The metadata index is your authoritative inventory. Compliance becomes a metadata query.

// compute moves freely;
// data stays addressable.
