Updated CloudPools Supported Cloud Providers

Jason He Oct 14, 2026

The Dell PowerScale CloudPools feature of OneFS allows tiering, enabling you to move cold or infrequently accessed data to lower-cost cloud storage. CloudPools extends the PowerScale namespace to the private cloud and the public cloud.

This blog focuses on CloudPools supported cloud providers.

CloudPools supported cloud providers

Each cloud provider offers a range of storage classes that you can choose from based on data access and cost requirements. CloudPools does not support some specific storage classes that may cause CloudPools operations failure due to unacceptable object read/write latency.

Table 1. Supported and unsupported cloud providers and storage classes for CloudPools

Cloud providers	Supported storage classes	Unsupported storage classes
Dell ECS / ObjectScale	All	N/A
Amazon S3/C2S S3	S3 Standard	S3 Intelligent-Tiering S3 Standard-IA S3 One Zone-IA S3 Glacier Instant Retrieval S3 Glacier Flexible Retrieval S3 Glacier Deep Archive S3 Outposts
Microsoft Azure Blob Storage	Hot access tier	Cool access tier Cold access tier Archive access tier
Google Cloud	Standard storage Nearline storage Coldline storage	Archive storage
Alibaba Cloud	Standard	Infrequent Access(IA) Archive Cold Archive Deep Cold Archive
Wasabi with Dell ObjectScale	Wasabi Hot Cloud Storage	N/A

To address cost requirements, users can move objects from higher cost storage class to lower cost storage class on the cloud. The tiers are as follows:

Supported/Tier1 storage classes: CloudPools supports the storage classes.
Tier2 storage classes: For example, Amazon S3 supports using S3 Lifecycle policy to move CloudPools objects from the Tier1 storage class to the Tier2 storage class. This movement will not break CloudPools operations.
Tier3 storage classes: For example, Amazon S3 supports using S3 Lifecycle policy to move CloudPools objects from the Tier1 storage class to the Tier3 storage class. This movement will break CloudPools operations. CloudPools objects must first be moved to Tier2 storage class or Tier1 storage class to be accessed.

Table 2. Storage classes per tier per cloud provider in CloudPools

[1] Assumes no opt-in to Deep Archive Access Tier.
[2] Assumes real-time access is enabled.
[3] S3 directory buckets only allow objects stored in the S3 Express One Zone storage class and do not support S3 Lifecycle policies.
