  • Managing arbitration in mixed link rate wide ports
    Patent number: 9137005
    Abstract: Systems and methods presented herein provide for the management of link rates for connecting targets devices (e.g., storage devices) to initiators (e.g., host systems). In one embodiment, an expander includes a plurality of PHYs including a PHY having a first link rate and a PHY having a second link rate that is different than the first link rate. The expander also includes a link manager communicatively coupled to the PHYs and operable to process a connection request from an initiator for the first link rate, extract a timer from the connection request, and determine whether the first link rate is available. The link manager is also operable to start the timer when the link manager determines that the first link rate is unavailable and issue a response to the initiator to inform the initiator that the timer has started and that connection at the first link rate is delayed.
