Abstract
Embodiments are directed towards writing data to a shingle of storage devices enabling storage devices not in the shingle to be turned off. A shingle may be a sub-group of more than one storage devices selected from a larger group of storage devices. A plurality of data repair sets may be written to various subsets of the storage devices in the shingle. Each data repair set may include data block(s) and repair block(s)—with each block being stored on a different storage device in the shingle. When a condition is satisfied, the shingle may be modified to either remove at least one storage device from the shingle, add at least one other storage device to the shingle, or both. In various embodiments, the at least one other storage device may be a storage device in the group of storage devices that is not currently included in the shingle.
