Abstract: Systems and methods for dynamic throttling of input/output queues in data storage device arrays are described. Data storage devices are connected through the slots and corresponding lanes of a storage interface switch. A storage controller uses a delay inserted between host submission queues and backend submission queues to manage the priority of host storage commands using slot groups.

Abstract: Techniques for caching in a machine learning model (ML) hosting service are described. ML model usage data is aggregated from host usage data provided from each host of a first set of hosts, the ML model usage data including, for a particular ML model, a number of inference requests to the particular ML model. A priority order of hosts in a second set of hosts to service an inference request for the particular ML model is calculated. Based on the ML model usage data and the priority order, a set of ML models to load to a particular host in the second set of hosts is determined. The particular host is caused to load the set of ML models. A router is updated to direct ML model inference requests amongst the second set of hosts.

Abstract: Methods, systems and computer program products implementing hierarchical classification techniques are disclosed. A hierarchical classification system receives training data including labeled transaction records. The system determines tag sequences from the training data. The system clusters the tag sequences into clusters. The system determines a cluster-level classifier that is trained to predict a cluster for an input transaction record. The system determines a respective cluster-specific classifier for each cluster. The system trains the cluster-specific classifier to predict a label of entity of interest for an input transaction record, given a particular cluster. Upon receiving a test transaction record, the system first applies the cluster-level classifier to determine a particular cluster for the test transaction record, and then determines a label of entity of interest of the test transaction record by applying a cluster-specific classifier of that particular cluster.

Abstract: Systems and methods for application tunneling using a storage interface protocol for an application processor are disclosed. A host interface using the storage interface protocol may connect to a host system, receive a host storage command, and determine from the host storage command a set of application-specific executable parameters and target host data. The host interface may pass the application-specific executable parameters to an application processor circuit for processing the target host data and returning the resulting processed host data. An example configuration includes a data storage device using its NVMe controller to receive commands for an onboard data processing circuit, such as video transcoding FPGA.

Abstract: Systems and methods for data storage device firmware updates in a composable infrastructure are described. Recomposition of a system in a composable infrastructure may include downloading a firmware update to a data storage device, activating the firmware update in the data storage device, and receiving a reset command at the data storage device.

Abstract: Systems and methods for distributed storage systems using synchronous discovery logs for fabric subsystem discovery. Storage nodes may be configured with fabric services and a management service may provide synchronization of discovery logs across fabric subsystems and between peer fabric nodes. The peer fabric nodes may communicate with one another using a fabric network protocol and corresponding fabric subsystems may communicate with each peer fabric node. When a target subsystem fabric node updates its discovery log, the updated discovery log is sent to the corresponding peer fabric node. The corresponding peer fabric node sends the updated discovery log to each subsystem fabric node and to each peer fabric node for synchronization across all subsystem fabric nodes. A host may contact any subsystem fabric node for the updated discovery log.
