SANNASobjektumtárolás

SANNASobjektumtárolás is a term used in distributed storage to describe a scalable object storage approach for unstructured data. Data is stored as discrete objects with unique identifiers, metadata, and optional version histories. The model emphasizes durability, accessibility, and policy-driven lifecycle management across multiple nodes or regions.

Origin and scope: The term arose within the SANNAS research framework as a reference model for comparing object-oriented interfaces with data-centric architectures. It is commonly discussed in academic and industry contexts as a way to analyze performance, consistency, and governance in large-scale storage deployments.

Architecture and data model: Implementations separate a data plane that stores payloads from a metadata plane that tracks identifiers, metadata, and policies. Clients access objects via RESTful APIs, often with S3-compatible interfaces. Objects carry id, size, content type, timestamps, checksums, and user-defined metadata; namespaces and access controls provide isolation and security.

Features and deployment: Key features include replication or erasure coding for durability, versioning, lifecycle rules, and encryption at rest and in transit. SANNASobjektumtárolás is suited for cloud backups, media repositories, and scientific data archives, where scalability and auditability are essential.

Standards and interoperability: Many implementations aim for S3 API compatibility to enable integration with existing tools. Bridging to file protocols and integration with identity and logging services are common to support governance, compliance, and multi-tenant operation.
