Abstract: Examples described herein may include migration of data associated with a service to a container. An example method includes creating of a user virtual machine associated with a service and an associated virtual disk storing data associated with running the service, and creating a volume group and an associated storage container at a node of a computing system. The example method further includes storing a cloned version of the virtual disk into the storage container, and, in response to discovery of the cloned version of the virtual disk in the storage container, mounting the cloned version of the virtual disk on the volume group to provide access to clients running the service.

Abstract: A system and method include providing backup and restore capability to a cluster node. The cluster node includes a controller virtual machine (CVM) that is communicably coupled to a plurality of cloud platforms and provides the capability of carrying out backup and restore at the cloud platforms without having to run a CVM at the cloud platform. The CVM can backup objects to the cloud platform and store metadata information related to the object in storage. The CVM also takes snapshots of the object and stores the snapshots. The CVM also determines a changed data chunks that include the changes made to the object from the last snapshot. To restore the object, the CVM restores the object based, in part, on the snapshots, the changed data chunks, and the metadata stored at the node.

Abstract: A system and method include receiving a request to call a requested application programming interface (API) at a target cloud computing platform. The system and method further include determining that the requested API is unsupported by the target cloud platform. The system and method further include generating a set of workflows associated with the requested API. The system and method also include generating a set of tasks common to the plurality of cloud platforms including the target cloud platform based on the set of workflows. The system and method also include generating a set of target APIs associated with the target cloud platform based on the set of tasks and an identity of the target cloud platform. The system and method also include communicating the set of target APIs t to the target cloud platform.

Abstract: Disclosed is a mechanism for performing rolling updates in a networked virtualization environment for storage management. The approach is applicable to any resource in the system, including controller VMs, hypervisors, and storage devices. Integrated processing may be performed across multiple types of upgrades.

Abstract: A method for accessing files on a storage system is provided. A hash memory table including a plurality of hash buckets respectively corresponding to a plurality of index hash codes is built. Each of the hash buckets has a pointer pointing towards at least one entry. Each of the entries has a physical address field and a hash code field. The physical address fields respectively record physical addresses storing the files, and the hash code fields respectively record verification hash codes corresponding to the files. The index hash codes are generated by inputting keys of the files to an index hash function and the verification hash codes are generated by inputting keys of the files to a verification hash function. Then, the hash memory table is loaded into the buffer with a bucket-based replacement policy so that the files are able to be accessed according to the hash memory table.
