Abstract: A system and method to create a clone of a source computing system, the system including the steps of selecting a memory space coupled to the source computing system, retrieving uncoded data from the selected memory space, encoding the uncoded data by use of a bit-marker-based encoding process executing on a backup server, storing encoded data in a protected memory coupled to the backup server, wherein the protected memory is protected from a power interruption, retrieving the encoded data from the protected memory; and decoding the encoded data onto a target computing system, wherein the target computing system is separate from the source computing system.

Abstract: In one example, a method may include generating, by a computing device, a volume as a file in memory, where the volume may be based on an operating system (OS) image. The method may include attaching the file to a workload, booting the workload using the OS image, generating a version of the file with at least one block that underwent change and metadata associated with the change based on an input/output request to the volume, storing, by the computing device, the file and the version of the file on a storage device associated with the computing device, and recovering a version of the volume associated with the workload using the file and the version of the file stored in the storage device.

Abstract: A processor-implemented method, for continuing operation of a quorum based system is provided. The method detects a loss of quorum. A plurality of speculative configurations is created, whereby each speculative configuration is isolated from other speculative configurations in the quorum based system. Each speculative configuration continues to order requests during the creation of speculative configurations. The method selects and starts one of the plurality of speculative configurations as a new operational configuration. Ordered requests continue to the new operational configuration. The original configuration of the quorum based system is restarted in response to the plurality of speculative configurations not being isolated.

Abstract: A system and method for handling multi-node failures in a disaster recovery cluster is provided. In the event of an error condition, a switchover operation occurs from the failed nodes to one or more surviving nodes. Data stored in non-volatile random access memory is recovered by the surviving nodes to bring storage objects, e.g., disks, aggregates and/or volumes into a consistent state.

Abstract: Presented herein are methods, non-transitory computer readable media, and devices for efficiently repairing tree databases with variable-length records. Methods for repairing tree databases with variable-length records are disclosed which include: iterating the tree database, detecting at least one recoverable leaf block, reducing the at least one recoverable leaf block to its legally formatted contents, and writing the at least one recoverable leaf block back into the tree database; processing the at least one recoverable leaf block to ensure the at least one recoverable leaf block represents a disjoint region within a record space within the tree database; and rebuilding branch blocks as necessary to provide a lookup and organizational index for the at least one recoverable leaf block.

Abstract: An aspect includes coherency management between volatile memory and non-volatile memory in a through-silicon via (TSV) module of a computer system. A plurality of TSV write signals is simultaneously provided to the volatile memory and the non-volatile memory. A plurality of values of the TSV write signals is captured within a buffer of the non-volatile memory corresponding to a data set written to the volatile memory. Storage space is freed within the buffer as the data set corresponding to the values of the TSV write signals stored within the buffer is written to a non-volatile memory array within the non-volatile memory.

Abstract: Methods and apparatus for an inter-processor communication (IPC) link between two (or more) independently operable processors. In one aspect, the IPC protocol is based on a “shared” memory interface for run-time processing (i.e., the independently operable processors each share (either virtually or physically) a common memory interface). In another aspect, the IPC communication link is configured to support a host driven boot protocol used during a boot sequence to establish a basic communication path between the peripheral and the host processors. Various other embodiments described herein include sleep procedures (as defined separately for the host and peripheral processors), and error handling.

Abstract: A system and method is disclosed for performing agentless backup of a virtual machine using a temporary attached virtual disk. An example method includes creating a virtual machine disk in a datastore, loading a software application in the virtual machine disk, the software application being configured to collect metadata relating to at least one application executing in an operating system of the virtual machine, communicatively coupling the datastore to the virtual machine, collecting the metadata relating to the at least one application executing in the operating system of the virtual machine, generating a snapshot of the virtual machine, and storing a backup of the virtual machine in a backup archive based on the snapshot.
