Scality RING: Object Storage Ledger 2026 Scorecard

Part of the Object Storage Ledger (edition 2026-10-16). How the scores work: methodology.

Snapshot

Type: product
Owner: Scality (private, venture backed; offices in San Francisco and Paris; HPE strategic investor since 2016; 152 million USD raised by April 2018 per a Scality release)
Licence: Commercial, quote only; customers choose a percentage of all-NVMe Tier 0 capacity and pay more for it (TechTarget 2022-11); ADI is described as "open-code" with source available for inspection, no licence named
Latest release: RING 9.5.2.0 (current version on the Veeam Ready listings modified 2026-08-03; release date not published); the RING9 generation shipped 2022-11-17; earlier versions 8.5.5, 9.1.0 and 9.3.0.7 appear in Veeam tests
Support lifecycle: not published outside the login-gated documentation
Next milestone: none published with a date
Object lock: S3 Object Lock named on the product page; Governance is tagged in the Veeam Ready tests of 9.5.2.0 with Veeam Backup & Replication 13 (Veeam articles 298 and 590, modified 2026-08-03); compliance mode and legal hold are described only in generic Scality blog posts, not for a RING version; Veeam Ready Repository as Capacity Target since 2019-05-15 and as Primary Target since 2023-07-05; no Commvault, Rubrik or Cohasset document found
Tier: Commercial software
Archetype: Vision-led, thinly documented
Evidence grade: B. Two Veeam Ready listings (articles 298 and 590) and Scality's press releases were read directly; they supply the version numbers, the Veeam test configurations and the 2026 announcements. Scality's documentation sits behind an SSO login, so no release note was read. Feature detail comes from vendor pages, TechTarget and older HPE collateral found through search (grade B at best), and every score before 2022 is grade C.

What moved the score

Year	Domain	Change	Points	Trigger
2019	Immutability and compliance	0 → 1	+2.4	Veeam Ready Capacity Target (2019-05-15) without immutability
2019	S3 API fidelity	2 → 3	+3.0	Veeam Ready Repository listing published 2019-05-15, which needs working multipart and standard S3 semantics (grade C for the exact feature set)
2021	Immutability and compliance	1 → 3	+4.8	Veeam Ready Object with Immutability announced 2021-11-18 for RING alongside ARTESCA (vendor release); S3 Object Lock on the product page
2022	Ecosystem and openness	1.5 → 2	+0.5	RING9: public monitoring, reporting and placement APIs; Scality keeps its S3 server open source as Zenko CloudServer
2022	Lifecycle and tiering	2 → 3.5	+2.1	RING9: Storage Accelerator multi-level tiering from all-NVMe to QLC or HDD with a data placement API; tape and cloud in one namespace belong to ADI (2026-05) and are not confirmed as RING features
2022	Operations	2.5 → 3.5	+2.0	RING9: Prometheus and AlertManager stack, new dashboard, Scality Cloud Monitor and ScaleCare support, monitoring and placement APIs; no Terraform or fleet manager for RING found
2022	Performance and scale	3.5 → 4	+1.2	RING9: all-NVMe Tier 0 with Storage Accelerator tiering to QLC or HDD; exabyte scale is a vendor claim; no S3 over RDMA GA and no independent benchmark found
2022	S3 API fidelity	3 → 3.5	+1.5	RING9: IAM-compatible bucket policies and new monitoring, reporting and data placement APIs (release 2022-11-17)
2022	Security and multi-tenancy	2.5 → 3.5	+2.0	RING9: IAM-compatible bucket policies; CORE5 framework and unified multi-tenant namespace (vendor); FIPS and KMIP not found
2023	Durability and resilience	4 → 4.5	+1.2	Veeam Primary Target test on six nodes with network erasure coding 9+3 (2023-07-05); stretched two and three site deployments with a witness in HPE collateral; per-bucket policy and rebuild tests not read
2026	Immutability and compliance	3 → 3.5	+1.2	9.5.2.0: Governance tagged in the Veeam Backup & Replication 13 tests; compliance mode not shown for a RING version and no independent assessment found
2026	S3 API fidelity	3.5 → 4	+1.5	9.5.2.0: Veeam test with Backup & Replication 13 tags Immutability, IAM & STS and Governance; no published compatibility matrix, so 4 rather than higher

Direction, 2023 to 2026

Each release item carries one theme and one driver (V vision, C customer need, M market window, U upstream, P portfolio).

Centre of gravity: AI (3), Immutability (2), Lifecycle (2)
Blind spots (no items): S3 API, Durability, Performance, Deployment, Security, Operations, Protocols, Packaging, Licensing
Driver mix: Vision 56%, Customer need 0%, Market window 33%, Upstream 0%, Portfolio 11%
Idea-to-need index: 0.63 (0 = demand-pulled, 1 = thesis-pushed)

Credibility: 13.5 / 25

Criterion	Score	Basis
Cadence	3	Versions 8.5.5, 9.1.0, 9.3.0.7 and 9.5.2.0 exist between 2023 and 2026, so releases happen; no release date is published
Roadmap transparency	1.5	Documentation and release notes behind an SSO login; direction appears in press releases only
Say-do	3	The 2022 promise of day-one Veeam support was kept for Backup & Replication 12 and 13; the 2026 AI items carry no GA labels and cannot be checked yet
Velocity	3	RING9 was the last release with published capability detail (2022-11); 2026 brings many announcements and thin release detail
Lifecycle stability	3	Support windows unknown; RING continues as a core product while ADI is added beside it

Commercial risk: 13.0 / 25 (lower is better)

Criterion	Score	Basis
Price and licence volatility	2	No metric or price change found since 2023; prices are not public, so changes would not be visible either
Purchase constraints	3	Quote only, aimed at large deployments; no free or small edition of RING
Channel and access	3	Direct and partners; documentation, release notes and downloads need a login
Owner stability	2.5	Private, venture-backed company with no acquisition found; last disclosed funding round 2018
Cost of staying supported	2.5	Support windows and upgrade terms not published

Technical lock-in: 11.5 / 25 (lower is better)

Criterion	Score	Basis
Formats	3	Proprietary peer-to-peer layout with ARC erasure coding; objects leave only through the API
Export path	1.5	Standard S3 reads and bucket replication; no export tooling found
Stack coupling	3	Scality's own storage, metadata and supervisor stack on every node
Hardware / cloud coupling	1	Standard x86 servers from several vendors; runs air-gapped
Skills and tooling coupling	3	Vendor-specific operations and a small skills pool compared with Ceph

Integrator fit: 12.5 / 20

Criterion	Score	Basis
Partner programme openness	3.5	Channel programme refreshed 2026-06; hardware partners HPE, Supermicro, Lenovo and Bull; terms not published
Multi-tenancy and self-service	3.5	Multi-tenant namespace and VMware Cloud Director integration in production at providers (vendor); quotas and metering detail not read
API and infrastructure-as-code	3	S3, IAM-compatible, monitoring and placement APIs (RING9); no Terraform or Ansible content found
Skills and certification	2.5	Vendor training exists; a public certification track was not found

AI leverage: 8.0 / 20

How the product uses AI, scored per year like capability. Only GA counts.

Criterion	2019	2022	Today	Latest step
AI workload support	1	2	2.5	2026: WEKA tiering partnership (2026-02) and an RDMA KV cache connector in ADI with no GA statement; no GPUDirect or S3 over RDMA GA found
AI platform stack	0	0	1.5	2026: AI Inference Factory with open-weight models, sold as a licence or managed service (vendor, 2026-10-08); whether it runs on RING and its GA status are unverified
AI-assisted operations	0	0	2	2026: ADI Guardian AI agents with human approval, available through partners (vendor, 2026-05-12); no version and no GA label, so scored below a GA assistant
Agent openness	1.5	1.5	2	2026: ADI lists MCP extensibility (vendor); no documented MCP server for RING found

Year by year: 2015: 2.5 · 2016: 2.5 · 2017: 2.5 · 2018: 2.5 · 2019: 2.5 · 2020: 2.5 · 2021: 2.5 · 2022: 3.5 · 2023: 3.5 · 2024: 3.5 · 2025: 3.5 · 2026: 8

AI say-do, 2023 to 2026: 5 AI items announced; 2 GA, 1 still preview, 2 pending, 0 dropped. ADI and the AI Inference Factory are "available now" on the vendor's word; the RDMA KV cache connector has no GA statement; the F5 and WEKA partnerships are announcements without a product to check.

Scality's AI effort in 2026 sits in ADI and the AI Inference Factory, both described as available through partners without version numbers or release notes a buyer can read. RING itself contributes an NVMe tier and tiering partnerships. Nothing here has been verified beyond the press release, so every AI point is provisional until a readable release note appears.

Reading

RING scores on durability and scale: network erasure coding across sites, stretched deployments and a Veeam record that runs from 2019 to Backup & Replication 13 in 2026. It loses points for what cannot be read. No release date, no support window, no compliance-mode statement for a RING version and no price could be found, and the file protocols that older collateral describes are missing from the current product page. The 2026 direction is almost entirely AI announcements. A buyer should ask Scality for the RING 9.5 release notes, the Object Lock modes it supports and the status of NFS and SMB before treating the vendor claims as capability.

Open questions and items to re-score

Release dates of RING 9.1, 9.3 and 9.5 and the support lifecycle: documentation is behind a login.
Versioning and multipart upload were not shown in a readable RING source; the API score rests on the Veeam Ready tests and the vendor pages.
Object Lock compliance mode and legal hold on RING, and any Cohasset or similar assessment, were not found; only Governance is tagged in the Veeam tests.
NFS and SMB status in RING 9.5: present in older HPE collateral and Evaluator Group commentary, absent from the current product page.
Whether ADI, the RDMA KV cache connector and the AI Inference Factory are generally available and whether they run on RING or as a separate product.
Commvault and Rubrik validation, the price metric and the ADI licence were not found.
No dated RING release between RING9 (2022-11) and 9.5.2.0 was found, so 2024 and 2025 have no direction items.
