Abstract: Methods and systems for managing sets of transactions for replication are provided. A system includes a number of origination nodes forming a source array. A sequence number generator generates sequence numbers based, at least in part, on a time interval during which a transaction is received. A subset manager groups transactions into subsets based, at least in part, on the sequence number.

Abstract: A system that includes a storage volume comprising a plurality of regions. The system also includes a plurality of nodes to receive transactions related to the storage volume from one or more client computers and execute the transactions. Each node is designated as an owner of one region of the plurality of regions. Each one of the plurality of nodes includes a ticket dispenser for dispensing tickets that ensure that the transactions that are actively being executed have exclusive access to a storage object identified in the transaction.

Abstract: A system that includes a plurality of nodes configured to execute storage transactions. The nodes include a first node and a plurality of other nodes. The storage transactions are grouped into transaction sets that are to be executed in a predetermined order that ensures that dependencies between the transactions are observed. A cluster sequencer that resides on the first node is configured to increment a sequence number that identifies an active transaction set of the transaction sets and send the sequence number from the first node to the plurality of other nodes. Upon receipt of the sequence number, each one of the plurality of other nodes begins executing the transactions of the active transaction set without waiting for confirmation that all of the plurality of other nodes have the same sequence number.
