Abstract: The present disclosure discloses a display substrate, a control method thereof and a display device, and relates to the field of display technologies. The display substrate includes: a first substrate, a second substrate, a liquid crystal layer, a plurality of pixel electrodes, and a plurality of light-emitting elements. The plurality of pixel electrodes and the plurality of light-emitting elements are both disposed on a side, proximal to the liquid crystal layer, of the first substrate. When external ambient light is weak, the plurality of light-emitting elements in the display substrate may supply auxiliary light sources to the display substrate, such that the display substrate normally emits light to ensure a display effect.

Abstract: An apparatus comprises a processing device configured to receive a request to store data on a storage system, and to determine storage node correlation metrics for storage nodes of the storage system characterizing probabilities of input/output operations being directed to filesystems having data stored on the storage nodes.

Abstract: An apparatus comprises a processing device configured to identify storage workloads to be run on a storage system, and to determine a mix of input/output (TO) patterns associated with the identified storage workloads, the mix of IO patterns comprising a first set of IO patterns characterizing types of IO operations performed by a first storage workload and at least a second set of IO patterns characterizing types of IO operations performed by a second storage workload. The processing device is also configured to calculate an affinity metric for the mix of IO patterns, the calculated affinity metric characterizing a difference between (i) performance metrics for the mix of IO patterns running concurrently and (ii) the first and second sets of IO patterns running individually. The processing device is further configured to allocate the identified storage workloads to storage devices of the storage system based on the calculated affinity metric.
