Abstract: Systems and methods for internally preconditioning SSDs for various workloads are disclosed. One such method involves (1) receiving preconditioning parameters including an invalidity distribution across ribbons, a transfer size of workloads, and a randomness of workloads, (2) generating workload data including a percentage of random data and a percentage of non-random data, where the percentages are based on the randomness of workloads parameter, (3) determining preselected physical block addresses (PBAs) of a ribbon using the invalidity distribution parameter, (4) writing a portion of the workload data to each of the preselected PBAs of the ribbon using a preselected transfer size until the ribbon is full, where the transfer size is based on the transfer size of workloads parameter, (5) marking all PBAs of the ribbon that were not preselected using the invalidity distribution parameter as being invalid, and (6) repeating (2) to (5) until a preselected end condition is met.

Abstract: A storage device may include a data storage portion, including a plurality of blocks of data, and a controller. The controller may be configured to receive a command that includes an inherent trim request for the plurality of blocks of data. The controller may be configured to perform a trim operation on a first set of trim blocks from the plurality of blocks of data, which may include fewer than all blocks of the plurality of blocks of data and may include trim blocks on which the controller can complete the trim operation within a predetermined time. The controller may be configured to update a pending trim table to include an indication of a second set of trim blocks on which trim is to be performed, which may include blocks of data on which the controller cannot complete the trim operation within the predetermined time.

Abstract: An approach is provided in which a master thermal controller utilizes a primary fan manager to control fans included in a computer system to cool various devices. When the master thermal controller determines that the primary fan manager is unresponsive, the master thermal controller transfers master thermal control to a backup thermal controller. The backup thermal controller creates fan control information based upon sensor information corresponding to the various devices, and sends the fan control information to a backup fan manager. In turn, the backup fan manager adjusts the speed of the fans according to the fan control information.
