  • Patent number: 11308034
    Abstract: A system for performing continuous transaction log backups with minimal resource usage of the client computing devices that are processing the transactions is disclosed. The system detects at least one input/output (I/O) activity at a client computing device. The I/O activity can be associated with at least one database operation performed via the client computing device. The system then executes one or more native commands to backup transactions log data associated with the detected I/O activity to a virtualized location. Backing-up the transactions log data comprises dynamically identifying a mount path location corresponding to the virtualized location, and transferring the transactions log data to the dynamically identified mount path using the one or more native commands. The system can then perform data processing operations (for example, data chunking and deduplicating) on the transactions log data after it is received at the dynamically identified mount path location.

  • Patent number: 11263023
    Abstract: An information handling system includes a basic input/output system (BIOS) that performs a firmware boot operation. During the firmware boot operation, the BIOS determines whether a driver pack management controller setting is enabled within a baseboard management controller of the information handling system. In response to the driver pack management controller setting being enabled, the BIOS copies a binary utility from the baseboard management controller to a system memory, and creates an operating system specific platform binary table to point to the binary utility on the baseboard management controller. In response to the operating system being initialized, a processor invokes the binary utility, mounts a memory partition of the baseboard management controller as a virtual drive of the operating system, and executes the operating system specific binary stage under a fixed globally unique identifier to install a driver pack.

  • Patent number: 11099956
    Abstract: Snapshot-based disaster recovery (DR) orchestration systems and methods for virtual machine (VM) failover and failback do not require that VMs or their corresponding datastores be actively operating at the DR site before a DR orchestration job is initiated, i.e., before failover. An illustrative data storage management system deploys proprietary components at source data center(s) and at DR site(s). The proprietary components (e.g., storage manager, data agents, media agents, backup nodes, etc.) interoperate with each other and with the source and DR components to ensure that VMs will successfully failover and/or failback. DR orchestration jobs are suitable for testing VM failover scenarios (“clone testing”), for conducting planned VM failovers, and for unplanned VM failovers. DR orchestration jobs also handle failback and integration of DR-generated data into the failback site, including restoring VMs that never failed over to fully re-populate the source/failback site.

  • Patent number: 11100083
    Abstract: Example implementations disclosed herein include techniques for a ready only bufferpool for use in local nodes of a multi-node computing system. Read only transactions executed by a processor can reference a ready only bufferpool resident in a VRAM on the same node. If the desired data page is in the bufferpool the transaction can immediately read data records from the cached data pages. If the desired data page is not in the bufferpool, then the transaction can cause a copy of a corresponding data page in a secondary memory to be installed in the bufferpool. The bufferpool can include more than one copy of a data page simultaneously to handle and prevent cache line misses. Data page are dropped from the bufferpool based on an incrementing per data page counter.

  • Patent number: 10678655
    Abstract: A method, system and computer program product are disclosed for recovery in a virtualized environment using remote direct memory access (RDMA). In one embodiment, the method comprises operating a virtual computer system on a physical computer system, and the virtual system maintains in a memory area a record of a state of the virtual system. In this method, when defined error conditions occur on the virtual system, RDMA is used to pull the record of the state of the virtual system from that memory area onto a standby computer. This record on the standby computer is used to re-initialize the virtual computer. Embodiments of the invention provide methods that provide a very fast recovery from a virtual machine fault or error, while requiring much fewer resources than standard approaches. In embodiments of the invention, one spare real computer system can be used for backing up several virtual systems.

    Abstract: A computer system implementing transactional memory. The computing system includes a plurality of Single Instruction Multiple Thread (SIMT) cores and a conflicting address table (CAT) for each core. The CAT stores word addresses for reads and writes correlated with flags indicating whether a corresponding word is written or read by a committing transaction. The CATs for the different SIMT cores are coupled together by an interconnect. A commit unit (CU) is coupled to the SIMT cores and is configured to validate transactions. The cores access its CAT to access a first address of data affected by a first transaction to be committed at the CU. The first address is compared to a second address affected by a second transaction. When the first address matches the second address, the core delays or prevents committing the first transaction at the CU by pausing the first transaction or aborting the first transaction.

  • Patent number: 10496503
    Abstract: Embodiments described herein are directed to migrating affected services away from a faulted cloud node and to handling faults during an upgrade. In one scenario, a computer system determines that virtual machines running on a first cloud node are in a faulted state. The computer system determines which cloud resources on the first cloud node were allocated to the faulted virtual machine, allocates the determined cloud resources of the first cloud node to a second, different cloud node and re-instantiates the faulted virtual machine on the second, different cloud node using the allocated cloud resources.

  • Patent number: 10469318
    Abstract: Systems and methods commence upon detecting certain computing system specification change events. Changes are recorded in resource usage intent specification records that characterize desired states associated with respective resources of the computing system. The change event causes generation of a data state snapshot of data stored in the computing system. A state tuple is constructed to associate the desired state with the data state. The state tuple is committed to a version control system. At any time, a user or process can select a selected system state tuple from committed tuples stored in the version control system. The tuple is analyzed to determine its associated desired state and its data state. Actions are taken to restore the data state of the tuple to the computing system, and then bringing the computing system to the state of the tuple so as to reproduce the desired system state in the computing system.

  • Patent number: 10423609
    Abstract: Methods and apparatus for identifying consistent snapshot points for file systems in a distributed storage service in which a client may access a file system in backend storage via two or more access nodes. A snapshot coordinator initiates a two-phase commit to perform a snapshot epoch transition. The coordinator sends prepare messages to the nodes. In response, a node sends a response to the coordinator, stops issuing writes to the file system, sets a timer, and waits for a commit message. Upon receiving a response from all nodes, the coordinator sends a commit message. Upon receiving the commit or the timer expiring, the nodes increment an epoch counter and begin issuing writes to the file system tagged with the new epoch and indicating that a copy-on-write operation be performed. The transition is successful if all nodes respond to the request message; otherwise, the two-phase commit is retried.
