Abstract
A method for improving latency in storage systems, the method comprising, receiving one or more write commands from a host. Determining that one or more bits are not set for a grain associated to a write. Responsive to determining the one or more bits are not set for the grain associated to the write, sending a message to node M requesting node M to set the one or more bits for the grain associated to the write, requesting write data be transferred from the host. Transferring write data from the host. Submitting the write data to a local storage. Replicating the write data to a remote system and complete a write to the host, and notifying node M to clear the one or more bits for the write after a predetermined delay.
