Abstract
A method for measuring consistability of a distributed storage system is disclosed. The method includes determining at least one consistency level that the distributed storage system can provide. A plurality of failure classes can be determined for the distributed storage system. A probability of the distributed storage system to be in each of the plurality of failure classes can be measured. Each failure class can be mapped to the at least one consistency level. The probability of each failure class for each consistency level can be summed to determine an expected portion of time that the distributed storage system provides each consistency level.
