Abstract
A distributed storage system node is disclosed. The distributed storage system node may include at least one storage device, which may act as the primary replica for data subject to an Input/Output (I/O) request. A cost analyzer may calculate a local estimated time required to complete the I/O request at the primary replica, and a remote estimated time required to complete the I/O request at a secondary replica of the data. An I/O redirector may direct the I/O request to either the primary replica or the secondary replica based on the local estimated time required and the one remote estimated time required.
