Abstract: Failover methods and systems for a networked storage environment are provided. In one aspect, a read request associated with a first storage object is received, during a replay of entries of a log stored in a non-volatile memory of a second storage node for a failover operation initiated in response to a failure at a first storage node. The second storage node operates as a partner node of the first storage node. The read request is processed using a filtering data structure that is generated from the log prior to the replay and identifies each log entry. The read request is processed when the log does not have an entry associated with the read request, and when the filtering data structure includes an entry associated with the read request, the requested data is located at the non-volatile memory.

Abstract: A technique of receiving a write transaction directed to a group of memory parcels of a memory device from a client source. The technique determines a state of a first indicator used to indicate which one of two data structures contains a newer mapping of the group of memory parcels, while the other data structure contains an older mapping of the group of memory parcels. The technique determines a state of a second indicator used to indicate which one of the two data structures is in current use for the group of memory parcels and compares the states of the two indicators. When a data structure in current use does not contain the newer mapping, the technique changes the state of the second indicator to the state of the first indicator. The technique writes content of the write transaction to storage locations based on the newer mapping.

Abstract: Aspects of a storage device including a controller memory, a die memory, and a plurality of accumulators corresponding to individual DQs are provided for accelerated DQ training and error detection. A controller stores first data in the controller memory, transfers second data to the die memory over an n-bit bus, and receives n bits of the second data from the die memory based on a DQS. The controller then compares n bits of the first data with n bits of the second data to produce n bit results received into respective accumulators, and the controller simultaneously updates different accumulators in response to bit mismatches. During DQ training, if an accumulator value meets a mismatch threshold, the controller modifies a DQS-DQ timing accordingly. During error detection of a read scrambled page, if an accumulator value does not meet an entropy threshold, the controller identifies an error associated with the page.

Abstract: One or more techniques and/or systems are provided for migrating a trust relationship. For example, a first storage cluster and a second storage cluster have a disaster recovery relationship where the second storage cluster provides failover client access to replicated data, replicated from the first storage cluster to the second storage cluster, in the event the first storage cluster fails.

In the event the first storage cluster fails over to the second storage cluster due to a disaster at the first storage cluster, the trust relationship is migrated to be between the second storage cluster and the third storage cluster for non-disruptive mirroring of data to the mirrored volume.

Thus, the automatic defect resolution system drives out all production defects over a window of time, requiring less and less maintenance over time. Once a given defect is fixed, the corresponding change is applied to the production environment to avoid future similar defects.

Abstract: System and method are disclosed to detect potential failures in a network-on-chip (NoC) before the potential failures happen. The system tests connectivity from a master to all slaves by sending scrub transactions to test all paths. The scrub transactions are identified using a scrub bit. The scrub transactions are generated at a master scrubbing block/unit and terminated at a slave scrubbing block/unit. The slave scrubbing block sends scrub responses to the scrub transactions along the response path. The scrub responses to the scrub transactions are generated at the slave scrubbing block and terminated at the master scrubbing block. This allows detection of potential failures, which are reported to a system monitor. If a potential failure is detected, the system transitions to a fail-safe mode before the failure occurs.

Abstract: Various embodiments provide for determining problematic components of an application that may cause user experience issues when running the application, and preemptively turning off or disabling the problematic components so that the application is rendered without the problematic component. When a component is rendered, various runtime data is produced. Such data may be logged and analyzed, and used to generate performance metrics of the component. Such performance metrics can be used to determine whether a component should be disabled. When a component is disabled, it become unavailable and will be excluded from the application when the application is rendered and/or served to a user. Thus, when an application is rendered or served, only available or enabled components are included.
