Abstract: Disclosed is an approach for overseeing the overall state of a virtual storage system, and for taking actions as necessary to manage the health and efficient performance of that system. A curator entity is provided on a distributed basis to manage and perform these functions. A master curator manages this workload that is performed by multiple slave curators. MapReduce operations are performed to implement the curator workload. Periodically, the master curator coordinates a full scan of all the metadata in the system using three MapReduce operations. Partial scans may also be run using a single MapReduce operation.

Abstract: A method for leveraging hypervisor functionality for maintaining application consistent snapshots in a virtualization environment deployed by the hypervisor includes utilizing the hypervisor to generate a hypervisor-specific application consistent snapshot of a virtual machine running in the virtualization environment, taking a storage controller specific application consistent snapshot of the hypervisor-specific application consistent snapshot of the virtual machine, and logically deleting the hypervisor-specific application consistent snapshot.
