Abstract: Methods and systems for managing manifests for replication are provided. A system includes a number of origination nodes forming a source array. A remote copy ticket dispenser provides a replication ticket for a transaction to be grouped with other transactions and to be replicated to a destination array. A transaction communicator sends transactions to the destination array.

Abstract: Methods and systems for collision handling during an asynchronous replication are provided. A system includes a cache memory system comprising a number of cache memory pages. A collision detector detects when a host is attempting to overwrite a cache memory page that has not been completely replicated. A revision page tagger copies the cache memory page to a free page and tags the copied page as protected.

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.
