Abstract

See full text

A method includes issuing, by a first computing device, first write requests for a first version of the data object. The method further includes issuing, by a second computing device, second write requests for a second version of the data object. The method further includes sending, by each of a first group of storage units, a first write response to the first and second computing devices. The method further includes sending, by each of a second group of storage units, a second write response to the first and second computing devices. The method further includes determining, by the first and second computing devices, whether a threshold number of first or second write responses were received. When the threshold number of the first write responses were received, the method further includes continuing, by the first computing device, the first write operation and establishing, by the second computing device, a write retry.
