Abstract: Systems and methods for failure recovery in shared storage operations. An example method comprises: acquiring, by a processing device, a lock with respect to a storage domain comprising a specified disk image; creating a transaction marker associated with the disk image, wherein the transaction marker is represented by a pre-defined tag associated with a logical volume of a block-based storage, wherein the logical volume implements a data area of a new volume associated with the disk image; creating a component of the new volume associated with the disk image; destroying the transaction marker by removing the pre-defined tag representing the transaction marker from the logical volume; and releasing the lock with respect to the storage domain.

Abstract: A delta store giving row-level versioning semantics to a non-row-level versioning underlying store is described. An example method includes establishing a column-based in-memory database including a main store and a delta store, where the main store allows only non-concurrent transactions on a same table and the delta store has a plurality of row-visibility bitmaps implementing a row-level versioning mechanism that allows concurrent transactions on the same table. A local RID space is established for a table fragment, that for each table in the database, the data of the table is stored in one or more main table fragment in the main store and in one or more delta table fragments in the delta store. Each table fragment has a local RID space, and the local RID space is a collection of one-based contiguous integer local RIDs (Row IDs) describing local positions of the rows of the table fragment.

Abstract: In one embodiment, a system for managing communication connections in a virtualization environment includes a plurality of host machines implementing a virtualization environment, wherein each of the host machines includes a hypervisor, at least one user virtual machine (user VM), and a distributed file server that includes file server virtual machines (FSVMs) and associated local storage devices. Each FSVM and associated local storage device are local to a corresponding one of the host machines, and the FSVMs conduct I/O transactions with their associated local storage devices based on I/O requests received from the user VMs. Each of the user VMs on each host machine sends each of its respective I/O requests to an FSVM that is selected by one or more of the FSVMs for each I/O request based on a lookup table that maps a storage item referenced by the I/O request to the selected one of the FSVMs.

Abstract: The present disclosure provides a computer program product and activity recording system for identifying idleness in a processor via a concurrent software environment. A thread state indicator records an indication of a synchronization state of a software thread that is associated with an identification of the software thread. A time profiler identifies a processor of the computer system being idle and records an indication that the processor is idle. A dispatch monitor identifies a dispatch of the software thread to the processor. In response to the dispatch monitor determining the indication identifies that the processor is idle and the indication of a synchronization state of the software thread indicating the software thread ceases to execute in the processor, the dispatch monitor generates a record attributing the idleness of the processor to the software thread and the indicated synchronization state.

Abstract: Systems and methods for generating random address mapping in non-volatile memories using local and global interleaving are provided. One such method for generating a random address mapping for a non-volatile memory (NVM) involves identifying a number of bits (N) in a physical address space of the NVM, selecting G bit(s) of the N bits to be used for global interleaving, where G is less than N, determining a number of bits (N-G) to be used for local interleaving, mapping the G bit(s) using a mapping function for global interleaving, interleaving (N-G) bits using an interleaving function for local interleaving, and generating a combined mapping comprising the mapped G bit(s) and the interleaved (N-G) bits.

Abstract: A computer-implemented method, carried out by one or more processors, for a modified asynchronous replication session. In an embodiment, the method comprises the steps of acquiring a lock on a volume configuration, where the lock prevents changes to the volume configuration between a first volume and a second volume at a remote site. Internal control block information is updated, where the update includes at least a volume serial number of the first volume matching a volume serial number of the second volume. Responsive to updating internal control block information, the acquired lock is released to allow changes to the volume configuration.

Abstract: Autonomous recovery from a transient hardware failure by executing portions of a stream of program instructions as a transaction. A start of a transaction is created in a stream of program instructions executing on a first processor of a multi-processor computer. A snapshot of a system state information is saved when the transaction begins. When the transaction ends, store data of the transaction is committed. If a transient hardware failure occurs, the transaction is aborted without notifying the computer software application that initiated the stream of program instructions. The transaction is re-executed on a second processor of the multi-processors, based on the saved snapshot of the system state information.

Abstract: Autonomous recovery from a transient hardware failure by executing portions of a stream of program instructions as a transaction. A start of a transaction is created in a stream of executing program instructions. A snapshot of a system state information is saved when the transaction begins. When a predefined number of program instructions in the stream are executed, the transaction ends, and store data of the transaction is committed. A new transaction then begins. If a transient hardware failure occurs, the transaction is aborted without notifying the computer software application that initiated the stream of program instructions. The transaction is re-executed, based on the saved snapshot of the system state information.
