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: Disclosed is an improved approach for using advanced metadata to implement an architecture for managing I/O operations and storage devices for a virtualization environment. According to some embodiments, a Service VM is employed to control and manage any type of storage device, including directly attached storage in addition to networked and cloud storage. The advanced metadata is used to track data within the storage devices. A lock-free approach is implemented in some embodiments to access and modify the metadata.

Abstract: A method for performing distributed data replication from a source cluster of nodes to a destination cluster of nodes includes electing a master file management instance and slave file management instances for the source cluster of nodes, identifying a set of files to be replicated, assigning the identified set of files to the master file management instance and the slave file management instances, processing the identified set of files by the master file management instance and the slave file management instances and performing replication on the processed set of files by file replication instances corresponding to the master and slave file management instances at the source cluster of nodes.

Abstract: Disclosed is an improved approach for implementing a storage system having an operation log where data writes are initially performed to a fast operation log, rather than to its permanent storage location. A distributed operation log can be employed to replicate the data to multiple locations in the storage system.
