Abstract: An illustrative embodiment disclosed herein is a computer-implemented method. In some embodiments, the method includes uploading, by a processor, an object to a source bucket in an object store and creating, by the processor, a lambda bucket in the object store that is symlinked to the source bucket. In some embodiments, the lambda bucket is associated with a transformation function. In some embodiments, the method includes associating, by the processor, a lambda function with the object in the source bucket, receiving, by the processor, a request to download the object from the lambda bucket, detecting, by the processor, that the object is in the source bucket and associated with the lambda function, fetching, by the processor, the object from the source bucket, generating, by the processor, a transformed object by invoking the lambda function and the transformation function on the object, and downloading, by the processor, the transformed object.

Abstract: A technique improves storage efficiency of an object store configured to maintain numerous snapshots for long-term storage in an archival storage system by efficiently determining data that is exclusively owned by an expiring snapshot to allow deletion of the expiring snapshot from the object store. The technique involves managing index data structures to enable efficient garbage collection across a very large number of data objects. When a snapshot expires, the technique obviates the need to scan the numerous snapshot data objects to determine which index structures are no longer needed and can be reclaimed (garbage collected). The technique is directed to management of underlying storage based on different sets of policies. When certain snapshots expire and are ready for deletion, the technique is directed to finding those data blocks that are no longer referenced (used) by any valid snapshots.

Abstract: One embodiment of the present invention provides a system for facilitating layer-2 subnet extension. During operation, the system can query, from a first administrative domain, a remote database of a second administrative domain for configuration information associated with one or more remote network segments. The system can obtain, from a user interface of the first administrative domain, an instruction for performing layer-2 subnet extension from a first network segment under the first administrative domain to a second network segment of the one or more remote network segments for providing a common layer-2 broadcast domain. The system can then send a remote instruction executable in the second administrative domain for configuring a remote endpoint for the extension. The system can also configure a local endpoint in the first network segment for the extension. Subsequently, the system can establish a data connection between the local and remote endpoints for the extension.

Abstract: Methods, systems and computer program products for implementing high-availability file services in a clustered computing environment. Two or more clusters are interconnected to carry out operations for replication of file content between file servers. The file servers and their respective network links are registered with a file server witness. The file servers operate in synchrony, where each file I/O is replicated from one file server to another file server over a first set of network paths. A file server witness communicates with each file server using a second set of two or more network paths interfaced with respective file servers. The file server witness monitors the file servers to determine operational health of the file servers. Upon receipt of a file I/O request, the file I/O request is directed to one of the two file servers based at least in part on the determined operational health.

Abstract: Methods, systems and computer program products for computer system data management. A leader node that is in a leader-follower relationship with a follower node is deployed to manage metadata across a plurality of interconnected computing nodes of the computer system. Upon a failure of any sort that results in a loss of operation or a disconnection of the leader node, the followers undertake steps to bring up a new leader. Such steps to bring up a new leader include electing a new leader to replace the lost or disconnected leader and initializing the data state of the new leader node by causing the leader to request incremental snapshots from followers. Additional metadata that might have changed since closing the incremental snapshots can also be retrieved from the followers. The metadata that might have changed since the time of closing the incremental snapshot is subjected to verification using a consensus algorithm.
