Abstract: System and method for implementing parallel Change File Tracking (CFT) between a distributed File Server Virtual Machine (FSVM) system and a scale-out backup system using underlying snapshot technology. The FSVM system executes efficient assignments of backup streams between worker nodes of the backup system and computing nodes of the FSVM system based on the number of available worker nodes at the backup system. The assignment of backup streams allows for parallel processing of incremental backup data based on successive data file snapshots. The parallel incremental backup may, for example, be per node, per share, or per data size across nodes or shares.

Abstract: Methods, systems and computer program products for computer cluster management. Multiple components are operatively interconnected to carry out operations for placing virtual machines onto a multi-tenant computing cluster, where the placement achieves adherence to a set of security requirements. Initially, data characterizing logical CPU resources of the multi-tenant computing cluster are gathered. Upon receipt of a request to place a virtual machine onto a node of the multi-tenant computing cluster, a set of security rules that are used to achieve the set of security requirements associated with the multi-tenant computing cluster are accessed. In accordance with the security rules the virtual machine is assigned to execute in a portion of the logical CPU resources. The virtual machine does not share logical CPU resources with any other tenant.

Abstract: Systems for storage system rollover and rollback. A data mover agent is installed on a source storage system to capture disaster recovery data and send to a target system. Upon receiving a rollover event signal, a virtualized controller creates one or more replica user virtual machines running on the target system that serve to replicate functions of the user virtual machines from the source storage system. The virtualized controller on the target system converts the target disaster recovery data from a first format to a second format to facilitate use of the target disaster recovery data by the replica user virtual machines. Rollback is initiated when the target system receives a rollback event signal. Differences in the data that have occurred between the rollover event and the rollback signal are calculated and sent to the rollback system. The calculated differences are applied to a registered snapshot on the rollback system.

Abstract: Methods, systems and computer readable medium for fast cluster upgrades. The disclosed techniques can be applied during an upgrade of a multi-node cluster when upgrading cluster software and/or hardware. Techniques applied include pausing a virtual machine (VM) at a first node, then communicating then-current states of the paused VM to a second node that executes a migrated clone of the paused VM. While the migrated cloned VM is running at the second node, changes to states of the cloned VM are tracked. When the upgrade of the first node has completed, then when migrating the cloned VM back to the first node, only the tracked state changes of the cloned VM are sent from the second node to the first node. The tracked state changes are used to update the states of the paused VM at the first node. The updated VM is resumed at the first node.

Abstract: Systems, methods, and computer program products for distributed data storage. A spot defragmentation method commences upon receiving an incoming storage I/O command to access a subject logical object that is composed of subject logical data blocks. The method continues by retrieving a block map that characterizes spatial relationships between the subject logical data blocks and instances of respective subject physical data blocks that store the subject logical object on a storage device. During processing of the incoming storage I/O command, the method determines occurrences of, and locations of one or more fragmented physical data blocks. A defragmentation operation is initiated to coalesce the fragmented physical data blocks to another location. The defragmentation operation is initiated before completing the storage I/O command.
