Abstract:
A method for replicating data in cluster environments may include (1) identifying a cluster of nodes configured to replicate common storage of the cluster, (2) identifying a first write operation issued by a first node to the common storage, (3) identifying a second write operation issued by a second node to the common storage after the first write operation, (4) identifying a completion time of the first write operation, (5) identifying a start time of the second write operation, (6) identifying a maximum potential skew between the first system clock and the second system clock, (7) determining that the first and second write operations are mutually independent by determining that the start time of the second write operation precedes the completion time of the first write operation by a span greater than the maximum potential skew, and then (8) replicating the first and second write operations in parallel.
