摘要： A SAS expander that includes a virtual device manager and a communications manager. The virtual device manager is to generate a virtual device table comprising virtual device PHYs associated with virtual device drivers for host device drivers to allow communication between the host device drivers. The communications manager is to receive a request from a first host device driver of a first host to communicate with a second host device driver of a second host, and in response to receipt of the request, establish communication between the first host device driver and a virtual device PHY associated with a virtual device driver of the second host device driver.

摘要： A SAS method to control host controller failure that includes, in response to receipt of a failure signal indicating that a host controller has failed, sending a wakeup signal to a host cache module of the failed host controller to cause the host cache module to determine whether there is trapped data in the host cache module that has not been transferred to a storage system. In response to receipt of a cache state signal indicating that there is trapped data in the host cache module that has not been transferred to the storage system, initiating transfer of the trapped data from the host cache module of the failed host controller to a host cache module of another host controller.

摘要： A hardware device detects change messages broadcast within a system. The system includes the hardware device, one or more controller devices, one or more expander devices, and one or more target devices interconnected among one another. The hardware device determines whether the change messages were broadcast within the system every first period of time or less for at least a second period of time, the first period of time less than the second period of time. In response to determining that the change messages were broadcast within the system every first period of time or less for at least the second period of time, the hardware devices signals that an error has been detected.
