Abstract: A method begins by a computing device of a dispersed storage network (DSN) selectively bringing online and taking offline storage units of a set of storage units of the DSN. When bringing a first storage unit of the set of storage units online in accordance with the selectively bringing online and taking offline storage units, the method continues with the computing device determining a rebuilding approach of the first storage unit. The method continues with the computing device bringing the first storage unit online in accordance with the rebuilding approach.

Abstract: A method includes detecting a storage error associated with a first memory device of a storage unit of a set of storage units, where data is error encoded into a set of encoded data slices and stored in a plurality of memory devices of the set of storage units, and where the plurality of memory devices includes the first memory device. The method further includes determining attributes associated with the first memory device and determining attributes of other memory devices of the plurality of memory devices. The method further includes selecting a memory device from the other memory devices based on the attributes of the memory device comparing favorably to the attributes associated with the first memory device. The method further includes rebuilding an encoded data slice associated with the storage error and storing the rebuilt encoded data slice in the selected memory device.

Abstract: Methods and systems for use in a storage network to prioritize storage units for data storage operations. In various examples, a device obtains data storage cost information relating to the storage network and resource utilization information for a plurality of storage unit sets. The device also determines pending resource demand information for storage units of each of the plurality of storage unit sets. The device further groups, based on at least one of the resource utilization information or the data storage cost information, the storage units into an underutilized resource group and an over utilized resource group and selects, based on at least one of the resource utilization information or the pending resource demand information, a storage unit set of the plurality of storage unit sets for storing new data. The device further issues high priority write access information to storage units of the selected storage unit set.

Abstract: A method for execution by one or more computing devices of a storage network includes obtaining status information from a set of distributed storage units that is storing a set of encoded data slices, where the set of distributed storage units includes inactive storage units and active storage units that are rotated between active and inactive in accordance with a rotation scheme. The method further includes activating, based on the status information, a first storage unit of the inactive storage units in accordance with the rotation scheme. The method further includes determining an encoded data slice stored in the first storage unit needs rebuilding and rebuilding the encoded data slice utilizing other encoded data slices of the set of encoded data slices. The method further includes deactivating, based on the status information, a second storage unit of the active storage units in accordance the rotation scheme.

Abstract: 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.
