ObjectScale review 2026
Dell ObjectScale (formerly ECS) · Dependable builder, thinly documented
ObjectScale ranks #9 of 21 S3-compatible object storage products in the Object Storage Ledger 2026, with a Ledger Index of 59.1 out of 100. Dell ObjectScale, the merged ECS line since 4.0, scores on durability, scale and 2026 S3 over RDMA work, while staying tied to Dell hardware and login-gated release notes.

What the Ledger says
ObjectScale scores on durability and scale, both inherited from ECS, and on the 2026 performance work that put S3 over RDMA across the all-flash line. Immutability is solid with two Veeam listings and admin-consensus protection, yet no independent assessment exists. The costs are structural: Dell hardware or qualified PowerEdge only, a merge that gates upgrades at ECS 3.8.x, and release notes nobody outside a Dell login can read. A buyer should ask Dell for the ObjectScale Product Availability Guide and the status of NFS, HDFS and the TLS 1.3 data path before planning a migration from ECS.
ObjectScale's AI case is throughput: S3 over RDMA and KV cache offload for inference arrived in 4.2 and 4.3 with Dell test figures but no independent numbers. The data platform side is partner certifications and a preview of S3 Tables. There is no AI in operations and no agent interface beyond the APIs and Terraform.
Capability by area
Buying, lock-in and release record
Buying and licence (commercial risk)(lower is better)
- Price and licence volatility2.5
- No public prices, so changes are invisible; the 4.0 update was free with ProSupport; CapEx or OpEx options
- Purchase constraints3.5
- Hardware bundles; software only on qualified PowerEdge or OpenShift; no small edition beyond a developer version
- Channel and access3
- Dell direct and partners; documentation, release notes and patches behind a Dell sign-in
- Owner stability1
- Large listed owner since 2016; no change
- Cost of staying supported3
- Hardware refresh pattern (EX300 sales end 2022, support end 2027) and an upgrade gate at ECS 3.8.x; software windows not found
Technical lock-in(lower is better)
- Formats3
- Proprietary chunk store with small objects packed into 128 MB chunks; data leaves through the S3 API
- Export path1.5
- Standard S3 reads and geo-replication; no export tooling found
- Stack coupling3
- Own Kubernetes-based microservice stack on every node
- Hardware / cloud coupling3
- Dell appliances or qualified PowerEdge servers only; runs on-premises
- Skills and tooling coupling2.5
- Dell-specific operations; a sizeable Dell services and partner pool
Release credibility
- Cadence3.5
- 4.0 (2025-04), 4.1, 4.2, 4.3.0.0 (about 2026-04) and 4.3.0.1: a minor release roughly every four to six months; dates not published
- Roadmap transparency2
- Blogs name coming features with footnotes; release notes and the availability guide need a Dell login
- Say-do3
- X560 and XF960 shipped on their dates and the Wasabi service reached a Veeam listing; TLS 1.3 on the data path, S3 Tables GA, X7700 and the NVIDIA certification are still open
- Velocity3.5
- RDMA, a new key-value store, wider erasure coding, compression and S3 Tables within about a year
- Lifecycle stability2.5
- The ECS to ObjectScale merge with an upgrade gate at 3.8.x and a product rename; appliance generations age out on Dell's schedule
Partners and services
- Partner programme openness3.5
- Dell partner programme; the Wasabi hybrid service shows a provider channel; terms not read
- Multi-tenancy and self-service3
- Namespaces and tenant separation from ECS (grade C); quotas and self-service not read this edition
- API and infrastructure-as-code3.5
- REST API reference for 4.3, Terraform and Kubernetes COSI
- Skills and certification3
- Dell certification exists; an ObjectScale track was not verified
