CloudPools software provides a cloud storage tiering capability which is built on the SmartPools data management framework. CloudPools enables data to be stored in a cold or frozen data tier or archive, thereby taking advantage of lower-cost, off-premises storage.
File pool policies define which old or unused data on a cluster should be archived to the cloud. The supported cloud storage options include Amazon S3, Microsoft Azure, Google Cloud, Alibaba, Dell ECS, and OneFS to OneFS through the OneFS RAN (RESTful access to namespace API). CloudPools automatically optimizes and protects the transfer of data to cloud storage with the use of both encryption and compression.
Although file data is moved to remote storage, the files remain visible in the OneFS file system. CloudPools accomplishes this by retaining a local SmartLink (or stub) file, which is a pointer to the location of data in the cloud. CloudPools is also integrated with the other OneFS storage management and protection services including SnapshotIQ, SyncIQ replication, SmartQuotas, and NDMP backup.
