In one example, the present storage solution provides an order of operations of a computer-implemented method that includes establishing bi-directional synchronous replication between one or more members of a first consistency group (CG1) of a primary storage site and one or more members of a second consistency group (CG2) of a secondary storage site with each storage site having read / write access while maintaining zero recovery point objective (RPO) and Zero recovery time objective (RTO). The method includes initiating a non-disruptive planned failover to change a role for the secondary storage site and change a role for the primary storage site while maintaining in sync status of the bi-directional synchronous replication between the one or more members of the CG1 of the primary storage site and the one or more members of the CG2 of a secondary storage site, and while maintaining zero data loss protection.

Techniques are provided for parsing files using node objects within a pool. Conventional techniques for parsing files, such as extensible markup language log files, may not efficiently parse the files, and thus cannot keep up with a rate at which the files are generated and / or populated (e.g., a storage system may generate a significant amount of log data stored in log files over time). The disclosed parsing technique is capable of more efficiently processing the files utilizing less memory and time. In particular, the files are parsed by threads that use node objects within a pool of memory (e.g., a sync pool) to store data being parsed and processed by the threads in parallel. When a thread finishes using a node object, the node object is cleared and returned to the pool for subsequent use by the thread or a different thread, which is memory efficient.

The system and method evaluates details contained in a sink data fusion including sink identification data from both the connected display devices 30 and at least one of the connected relay devices 40. Keywords, whitelists, and blacklists can be used to evaluate the content of the sink data fusion and determine a match for one or more preferred display devices to improve the selection of a set of function codes for controlling the connected display devices 30 using a controller device 50 paired with the content management device 20.

A storage device may maintain consistent guaranteed performance throughout the life span of the storage device. The storage device includes a data path from a host to a memory device and the data path includes sync points at components along the data. A calibrated time between adjacent sync points on a data path is measured and stored. During use, a controller determines that an event triggering less than the guaranteed performance on the storage device has occurred. The controller measures the calibrated time against a current time associated with the adjacent sync points. When the controller determines that a variance exists between the calibrated time and the current time, the controller applies a corrective measure to retune a data path parameter. The controller uses the retuned parameter to test a calibrated timer on the data path to maintain the guaranteed quality-of-service of the storage device.

The described technology is generally directed towards automatic storage of data / digital objects in a self-adaptive replication system. Data replication can be switched between synchronous (sync) replication and asynchronous (async) replication between a local storage system and a remote storage system. Latency between writing data to the local storage system and the remote storage system can be determined. In the event of the latency is less than a threshold value, sync replication can be utilized, and in the event of the latent is greater than the threshold value, async replication can be utilized. Accordingly, data replication can adapt based on infrastructure, volume of data to be write, period(s) of no-data writes, etc. Async replication can use a buffer to temporarily store data during a write operation at the remote storage system. Alternatively, a list can be maintained for data to write to the remote storage system for subsequent replication.

Disclosed herein is a system and method to synchronize files from a hosted file system where the client endpoint devices have direct access to the files stored on a hosted file store. When the client desires to synchronize with the files stored on the hosted file store the process identifies a sync role that can process the request. The particular sync role does not need to maintain state with the client device or the file store. The state necessary for the processing of the synchronization process is maintained separate from the sync role such that any sync role in the system can pick up the requests and process the requests. Once the role has been selected the synchronization process proceeds as normal. As state is not maintained by the sync role multiple roles can process the request or two roles can handle different portions of the process.

According to the invention, efficient and convenient synchronization of the local cache and the Redis cache is realized.

A set of configurable sync groupings (which may be referred to as sync zones) are defined. Any of the processors may belong to any of the sync zones. Each of the processor comprises a register indicating to which of the sync zones it belongs. If a processor does not belong to a sync zone, it continually asserts a sync request for that sync zone to the sync controller. If a processor does belong to a sync zone, it will only assert its sync request for that sync zone upon arriving at a synchronisation point for that sync zone indicated in its compiled code set.
