Abstract: Some techniques described herein relate to utilizing a machine-learning (ML) model to select respective samples for queries of a query sequence. In one example, a method includes receiving a query in a query sequence, where the query is directed toward a dataset. Samples are available as down-sampled versions of the dataset. The method further include applying an agent to select, for the query, a sample from among the samples of the dataset. The agent includes an ML model trained, such as via intent-based reinforcement learning, to select respective samples for queries. The query is then executed against the sample to output a response.

Abstract: Methods and structure for enabling Fast Context Switching (FCS) among a plurality of FCS enhanced Serial Attached SCSI (SAS) expanders of a SAS domain. The FCS enhanced SAS expander is further adapted to detect completion of utilization of the first connection that utilizes an upstream PHY and a downstream PHY of the expander. The expander is further adapted, responsive to detecting completion, to determine whether a second connection between the initiator device and a second target device could be established utilizing the existing coupling between the upstream PHY and the downstream PHY. The expander de-couples the upstream PHY from the downstream PHY within the expander in response to determining that the second connection does not utilize the existing coupling and maintains the existing coupling in response to determining that the second connection utilizes the coupling between the upstream PHY and the downstream PHY.
