Autonomous grain probe

An autonomous probing system includes a computer, a probe assembly, a PLC, and an optical sensor. The optical sensor captures image data of a probing environment. The probe assembly includes a moveable probe portion and a sensor. The probe portion is moveable between a first and second position. The sensor has a first sensor value that is indicative of the first position. The computer receives image data from the optical sensor and detects a vehicle positioned within the probing environment. The computer then determines one or more target areas within the vehicle and an X coordinate position and a Y coordinate position of one or more probe target points within each of the target areas. Based on the first sensor value and the X and Y coordinate positions, the computer determines a second sensor value, which is indicative of the second position and transmits the value to the PLC.

Efficient use of optional fast replicas via asymmetric replication

A method and a computer system for asymmetric replication of data are provided. Storage of a set of data is organized as a first copy and as a second copy in non-volatile storage. The second copy is reliable and stored so as to be readable at a speed slower than for the first copy. A read instruction regarding the set of data is received and performed preferentially via the first copy such that the asymmetric replication achieves enhanced performance speed. A request to execute a write operation is received. The write operation is executed to the first copy and to the second copy. In response to determining that the write operation to the first copy was unsuccessful, a label for the first copy is set as stale.

Interrupted replicated write recognition

A method for executing operation requests includes formatting one or more storage devices and selecting one or more labeled replicas and one or more distinguished replicas, receiving an operation request with respect to a set of data blocks, identifying a preferred replica corresponding to the received operation request, determining whether the replication-pending bits for the preferred replica are set, and executing the received operation request with respect to the corresponding distinguished replica. A method for executing a write operation request additionally includes setting replication-pending bits with respect to the labeled replica, wherein the replication-pending bits indicate an incomplete write request, writing data to both a labeled replica and a distinguished replica, and clearing the replication-pending bits with respect to the labeled replica to indicate the completion of the write operation. A method for executing a read operation additionally includes identifying a preferred replica with respect to the received read request.
