Abstract
Technologies are described herein for providing bi-directional communication between redundant storage controllers in a storage system. One of the storage controllers operates in the initiator role over a point-to-point communication channel connecting the controllers, while the other operates in the target role. To transmit a function call from a storage module executing on the initiator storage controller to a corresponding module executing on the target storage controller, the initiator storage controller issues a write command to the second storage controller over the point-to-point communication channel. In order to transmit a function call from a storage module executing on the target storage controller to a corresponding module executing on the initiator storage controller, the target storage controller responds to a pending anticipatory read command sent from the initiator storage controller over the point-to-point communication channel.
