Original Abstract Submitted
Methods and systems for use in a storage network to prioritize storage units for data retrieval operations. In various examples, a device obtains resource utilization information and pending resource demand information for a plurality of storage units of a storage network. The device further groups, based on the resource utilization information, the storage units into an underutilized resource group and an overutilized resource group, and further issues one or more high priority read slice access requests to the storage units of the underutilized resource group. The read slice access requests correspond to a pending resource demand for data retrieval. In response to determining that the high priority read access information does not include at least a read threshold number of read slice requests, the device further issues one or more additional read slice requests to one or more storage units of the overutilized resource group.
