READ, WRITE, AND RECOVERY OPERATIONS FOR REPLICATED DATA
摘要
Read, write and recovery operations for replicated data are provided. In one aspect, a system for redundant storage of data included a plurality of storage devices (102) and a communication medium (104) for interconnecting the storage devices (102). At least two of the storage devices (102) are designated devices (102) for storing a block of data. Each designated device (102) has a version of the data and a first timestamp that is indicative of when the version of data was last updated and a second timestamp that is indicative of any pending update to the block of data. The read, write and recovery operations are performed to the data using the first and second timestamps to coordinate the operations among the designated devices (102).
