Abstract: Provided is a method for performing a fetch-and-add, FAA, operation in a concurrent system. The method includes receiving a FAA request from a client at a primary node (200). The method includes locking a memory address corresponding the FAA request received at the primary node. The method includes calculating a new value for the memory address based on the FAA request. The method includes replicating the new value at one or more secondary nodes (204A-B). The method includes writing the new value to the memory address at the primary node.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for improved delivery likelihood of batch events. One of the methods includes receiving, from an upstream system in an event processing pipeline, a request to store a first batch of events in persistent memory, the request including the first batch of events and a first identifier for the first batch of events; providing, to a downstream system in the event processing pipeline, a data storage request that includes the first batch of events and the first identifier; receiving, from the downstream system, the first confirmation that includes the first identifier and indicates that the first batch of events was successfully committed; and in response to receiving the first confirmation: sending, to the upstream system, a second confirmation message that includes the first identifier and indicates that the first batch of events was successfully committed.

Abstract: A system and method is disclosed to create an application consistent recovery point in disaster recovery solution without knowledge of I/Os. The method in one embodiment includes a first application sequentially issuing first write commands for writing data to memory via a file system. The first application receives a command to pause after issuing the first write commands. The first application pauses in response to the first application receiving the command. All of the first write commands that are pending are completed after the first application is paused. After the all the first write commands are completed, a module issues a read command to read a marker.

Abstract: A cascaded data mover for cascaded backup system, includes primary storage having primary volume, secondary storage having backup data, tertiary storage having cascaded backup data and data mover. The cascaded data mover includes replication unit configured to replicate, by means of: creating bitmap of blocks change between last snapshot of primary volume and current snapshot available in backup data, and copying blocks from current snapshot to cascaded backup data according to bitmap. The cascaded data mover further includes control unit that instructs replication unit to jump to newer snapshot when certain percent of current snapshot is copied to cascaded backup data, by means of creating a difference bitmap, merging difference bitmap with bitmap, and copying blocks from newer snapshot according to merged bitmap. The system provides improved data storage by not moving to newer snapshot before completely coping certain amount of data from current snapshot.

Abstract: A memory controller is operatively connected to clients for shared memory access, and the memory controller is configured to perform a recovery of a shared memory by generating a backup snapshot of shared memory and restoring shared memory as per backup snapshot to a target file system. The memory controller is configured to prior to generating the backup snapshot: start snapshot timer; generate intermediate snapshot; restore shared memory as per intermediate snapshot to target file system; stop snapshot timer; determine if snapshot timer exceeds a snapshot time threshold, and if so generate another intermediate snapshot until snapshot timer is less than snapshot time threshold and then suspend memory operations. The memory controller is configured to, after generating backup snapshot, resume memory operations. The memory controller establishes an initial consistent synchronization point of shared memory and clients. Thus, incremental changes are stored without any data loss.

Abstract: The present invention discloses a method and system performed by a controller (201) for controlling redundancy functionality by configuring distant located redundant modules in a communication network. The method performed by the controller (201) comprising the steps of: creating (302) a redundant pair over the communication network (206) having a TSN; defining (304) a primary (202) and secondary module (204) based on a transmission of a signal to a first and second module; causing (306) the primary module (202) and the secondary module (204) to create a TSN stream configuration for communicating redundancy information between the primary (202) and secondary module (204); enabling (308) the primary module (202) to communicate (308) the redundancy information periodically over the TSN stream configuration to the secondary module (204); and triggering (312) the secondary module (204) to perform the function of the primary module (202) in response to determining at least one event.
