OneFS SyncIQ and CloudPools features are designed to work together seamlessly. CloudPools tiers data to a cloud provider. The cloud provider could be Dell’s Elastic Cloud Storage (ECS), a public, private, or hosted cloud. As data is tiered to a cloud provider, a small file is retained on the cluster, referred to as a SmartLink, containing the relevant metadata to retrieve the file at a later point. A file that is tiered to the cloud, cannot be retrieved without the SmartLink file. For more information about CloudPools, see or the .
If a directory on the source cluster is configured for data replication to a target cluster containing the SmartLink files, the SmartLink files are also replicated to the target cluster.
Note: Although configuration to a cloud provider exists on the source and target clusters, it is important to understand that only a single cluster may have read and write access to the cloud provider. Both the source and target cluster have read access, but only a single cluster may have read and write access.
During normal operation, the source cluster has read-write access to the cloud provider, while the target cluster is read-only, as illustrated in the following figure.
