Patent ID: 7877490

Claim:
A method comprising: receiving a first network connection to a client at a first node of a storage cluster; first migrating the first connection to a second node of the storage cluster; receiving a second network connection to the client at a third node of the storage cluster; second migrating the second connection to the second node of the storage cluster while the first connection is also migrated to the second node; ensuring jointly at the first, second, and third nodes: that timestamps associated with the connection continue to monotonically increase after the migrations; that packets associated with the connection are not dropped within the storage cluster after the second migration; that packets associated with the network connection do not conflict with other packets associated with a different network connection after the first migration, and after a concurrent third migration of the different network connection to the second node, wherein the client uses a virtual IP address for connection with the storage cluster, and wherein the migration occurs transparently to the client.
