A method for providing access to objects associated with a particular client in a cloud storage system is disclosed. The method includes the steps of establishing a connection with a user, providing a client namespace associated with the client to the user, where the client namespace represents objects stored on the cloud storage system and objects stored on a private storage system apart from the cloud storage system, receiving a request from the user to access an object stored on the private storage system, and providing information to the user to facilitate access to the object stored on the private storage system by said user. Other systems and methods are also disclosed. Important advantages of the present invention are facilitated by separating the logic for user access (control plane) from the actual storage (Storage plane). Private file system access can still be managed from the cloud, while keeping the client data private.

Systems and methods for facilitating access to private files using a cloud storage system

Embodiments offer a cloud system allowing workload management through the use of a zone-compartment architecture. A routing engine extracts an identifier from an incoming request to a cloud system. The routing engine then determines from a mapping in a service mesh, a target compartment corresponding to the identifier. Based upon the target compartment, the routing engine receives an IP address from a registry of the service mesh. Using the IP address, the routing engine routes the request to the target compartment for processing by an application. A database of the target compartment is replicated within another compartment within a different zone, thereby ensuring high availability. Based upon a recommendation provided by the zone, the target compartment may be split or merged to accommodate variations in workflow. The mapping and registry are updated according to changes in the compartments.

Cloud system architecture and workload management

A method for facilitating synchronization of a remote file system (RFS) and a local file system (LFS) includes maintaining a global revision identifier associated with the RFS, where the global revision identifier has a variable state, and responsive to the RFS being modified, updating metadata associated with one or more of the file system objects of the RFS based on a state of the global revision identifier. More particularly, the method includes updating the global revision identifier to a new state in response to the RFS modification and then updating the metadata of the folder(s) associated with the RFS modification. The RFS metadata is partitioned by folder and file to facilitate efficient searching based on a requested namespace view. Another method utilizes prior revision identifiers stored in the LFS to limit the RFS metadata returned to the local cloud during a rescan, by excluding the data set that has not changed, which improves the efficiency of the rescan synchronization.

The invention prevents improper deletes of file system objects during rescan synchronizations of local and remote (cloud) file systems. File and folder deletes are validated (confirmed) during a rescan synchronization using events generated for a steady state synchronization process. Any improper deletes are fenced and not allowed to proceed during synchronization. A method for synchronizing local (LFS) and remote (RFS) file systems includes monitoring the LFS for changes, generating a first set of events as part of a first synchronization routine (e.g., a steady state synchronization routine), generating a second set of events as part of a second (rescan) synchronization routine, validating selected events of the second set with events of the first set to determine whether each of the selected events of the second set is valid or invalid, and synchronizing the file systems based on the events of the second set excluding those that have been invalidated. Storage systems are also disclosed.
