A DCIG report looked at software-defined object storage and named its top five picks, but did not evaluate Dell EMC’s ECS or NetApp’s StorageGRID.
Eighteen vendor products were evaluated and the top five were Scality RING, Cloudian HyperStore, Hitachi Vantara HCP, MinIO and Nutanix Objects. These five products featured robust technical support facilities, public cloud support, wide deployment options (bare-metal, Linux, virtual machines, etc.), directory services integration, role-based access, data protection (erasure coding, replication), immutable storage protection (object locking), robust analytics and value-added services. The report does not specify whether they are classified in any particular way.
A November 2021 Gartner Critical Capabilities report evaluating 17 products from 15 vendors in the distributed file systems and object storage space places Scality at the top. It also included Dell EMC’s ECS and NetApp’s StorageGRID in its set of evaluated vendors and products.
The author of the report writes, “To arrive at the DCIG TOP 5 solutions included in this report, DCIG followed a seven-step process to arrive at the most objective conclusions possible. The process is as follows:
- The DCIG established which features would be evaluated.
- The characteristics have been grouped into five general categories.
- A survey was created and completed for each solution. Suppliers were given the opportunity to review and respond to the survey.
- DCIG identified solutions that met DCIG’s definition for an on-premises SDS object storage solution.
- The DCIG weighted each characteristic to establish a scoring rubric.
- The DCIG evaluated each solution based on the information gathered during its investigation.
- Solutions were ranked using standard scoring techniques.
However, the actual vendor scores were not disclosed by DCIG.
The 13 least important suppliers and products were:
- Helios cohesion
- DataCore software swarm
- space hammer
- IBM Cloud object storage
- iXsystems TrueNAS
- Nexustorage Limited Nexfs
- Red Hat Ceph Storage
- StoneFly StoneFusion
- StorONE S1 Enterprise Storage Platform
- Swiftstack Storage
- WekaIO WekaFS
- Zadara VPSA
Inclusion criteria for the DCIG report included:
- Commercially available from January 1, 2022.
- Sufficient, publicly available information is available for DCIG to make an informed decision.
- The solution must support the S3 API.
- The product may be available as a pre-integrated software and hardware appliance from a solution provider.
- If available as a pre-integrated appliance, the product should also be available on multiple OEM’s servers, as software that can be installed on other vendors’ hardware or run in the cloud.
We don’t see how these criteria could rule out Dell EMC and NetApp unless there is “sufficient, publicly available information for DCIG to make an informed decision.”
Dell describes the ECS product as: “Exabyte scale. Extreme performance. Enterprise level. ECS, Dell EMC’s premier object storage platform, delivers unmatched scalability, performance, resiliency and cost effectiveness. Deployable as a turnkey appliance or in a software-defined model, ECS offers rich S3 compatibility on a globally distributed architecture, enabling organizations to support enterprise workloads such as cloud-native, archiving, IoT, AI, and large-scale big data analytics applications. .“
NetApp says, “The StorageGRID software-defined object storage suite seamlessly supports a wide range of use cases across public, private, and hybrid multicloud environments. With industry-leading innovations, NetApp StorageGRID stores, secures, protects, and preserves unstructured data for versatile use, including automated lifecycle management for long periods of time.
Besides ignoring Dell and NetApp, the DCIG report didn’t examine Huawei’s Fusion Storage, Intel’s open source Distributed Application Object Storage (DAOS) product, or Quantum’s ActiveScale, but that may be because it was not classified as software defined.
