  • Disk initiated asynchronous event notification in an information handling system
    Patent number: 7548994
    Abstract: A SAS target device, e.g., SAS disk, may instantiate an asynchronous event notification (AEN) transaction while still conforming to SAS protocol standards. When the SAS target has an event queued up for notification to a host controller but there is no host initiated communication going on for the SAS target to attach the notification, then the SAS target may start an AEN timer. If the AEN timer expires and the AEN is still pending, then a request is made to the SAS target to notify the host controller using a SAS PHY level out of band (OOB) mechanism. The OOB message may be sent via a new OOB signal or by sending a COMINIT signal from the SAS disk PHY, requiring a link reset and then using a bit in an IDENTIFY frame for the pending AEN. Receiving and issuing an AEN may then be communicated during PHY initialization.
