Abstract: The present technology relates to identifying one of a plurality of artificial intelligence models based on a received key value. The received key value is applied to the identified one of the artificial intelligence models which is trained to output one of a plurality of actual index values. The one of the actual index values is compared to a range within the actual index values to determine when the one of the actual index value points to the data block. A received input-output operation is performed on the data block when the one of the actual index values is determined to point to the data block.

Abstract: Methods, non-transitory machine readable media, and computing devices that manage data storage fabric health are disclosed. With this technology, a network model is applied to network data determined from monitored network traffic exchanged between storage nodes and via network connections over a cluster fabric to generate a health score for the cluster fabric. A cause of health degradation in the cluster fabric is determined based on an analysis of the network data, when the health score indicates that health of the cluster fabric is degrading. A corrective action is automatically initiated based on the cause of health degradation in the cluster fabric. With this technology, cluster fabrics in data storage networks are more effectively monitored for health degradation and, advantageously, corrective actions can be preemptively initiated to improve performance.

Abstract: A method, non-transitory computer readable medium, and application host computing device that parses assembly language code to identify a transaction block including an assignment to a memory location, the assembly language code associated with an application and output by a compiler. The assembly language code is modified to insert an invocation of a plurality of functions collectively configured to facilitate persistent storage of one or more data updates associated with the assignment at run-time. The assembly language code is assembled to generate object code and the object code is linked with at least a run-time library including a definition for each of the plurality of inserted functions to generate an executable file for the application.

Abstract: A system and method for efficiently replicating data stored in a byte-addressable, persistent memory of a host computer. A user-level library of the host computer may configure the persistent memory as a software transactional memory (STM) system defined by operations, such as a STM commit operation, that ensure safe and consistent storage of the data within a region of the persistent memory. The library may then cooperate with an application executing on the host computer to control access to the data, e.g., to change the data, as a transaction using the STM commit operation. Within a context of the transaction, the library may precisely determine which bytes of the data have changed within the region, as well as how and when the data bytes have changed. Armed with precise knowledge of the context of the transaction, the library may efficiently replicate the changed data at the byte-addressable granularity.

Abstract: The embodiments described herein provide a system and method for efficiently storing small, random modifications or changes to data on one or more storage devices, such as disks, of storage servers coupled to a host computer in a network environment. Illustratively, the data is stored in a region of a byte-addressable, persistent memory of the host computer and is replicated (i.e., copied) as changed data of the region on the disks at the granularity at which it was modified, e.g., at the byte-addressable granularity. To that end, each storage server employs a data structure (e.g., a Fibonacci array) that is configured to efficiently accumulate the small, random data changes into one or more large blocks of changed data for storage on the disks in a manner that realizes the streaming bandwidth of the disk.

Abstract: A system and method enables efficient implementation of snapshots of data organized as arbitrary data structures on a byte-addressable persistent memory of a host computer. A user-level library of the host computer may configure the persistent memory as a software transactional memory (STM) system defined by operations, such as a STM commit operation, that ensure safe and consistent storage of the data (i.e., the data structures) within a region of the persistent memory. The library may then cooperate with an application executing on the host computer to control access to a data structure, e.g., to change a datum, stored in the region of the persistent memory as a transaction using the STM commit operation. Within a context of the transaction, the library may precisely determine which byte or bytes of the datum have changed within the region, as well as how and when the bytes have changed. Armed with precise knowledge of the context of the transaction, the library may efficiently implement a snapshot (i.e., point-in-time copy) of the changed datum and its associated data structure at the granularity at which it was modified, e.g., at the byte-addressable granularity.
