Techspeak
File integrity is preserved by a managed redundancy of three
block copies. Block servers broadcast and listen for regular
health messages from all members of the storage system. Missing
responses are first noted within a round-robin variable back-off
scheme that schedules the removal of a failed server and
the rebalancing of lost blocks among remaining servers. A
reliability of 99.999% can be calculated by considering the
probability of three successive hard-drive failures with
MTBs of 1 million hours within the time window of a rebalance
operation. |
