Abstract:
Exemplary methods, apparatuses, and systems determine that quorum can be maintained for a storage object in a distributed storage system in the event a defined maximum number of first partitions in a first level of storage and a second partitions in a second level of storage fail. When it is determined that there are insufficient numbers of first partitions and/or second partitions, additional first partitions and/or second partitions are associated with the storage object in the distributed storage system. A number of votes is calculated for distribution and an allocation is defined for assigning the votes to each component and witness component of the storage object.
