Methods and structure for configuring a Serial Attached SCSI domain via a Universal Serial Bus interface of a Serial Attached SCSI expander

摘要

Methods and structure are provided for managing a Serial Attached SCSI (SAS) domain via Universal Serial Bus (USB) communications. The system comprises a SAS expander. The SAS expander comprises a plurality of physical links, a USB interface, and a control unit. The control unit is operable to receive USB packets via the USB interface, to determine SAS management information based upon the received USB packets, and to alter a configuration of the SAS domain based upon the SAS management information determined from the USB packets.

1. A system for managing a Serial Attached SCSI (SAS) domain via Universal Serial Bus (USB) communications, comprising:
a SAS expander comprising:
a plurality of physical links;a USB interface; anda control unit operable to receive USB packets via the USB interface, and to detect SAS management information based upon the received USB packets,wherein the control unit is further operable to acquire passcode data from a storage device coupled to the SAS expander via the USB interface, to determine whether the passcode data is valid, and to alter a configuration of the SAS domain based upon the SAS management information determined from the USB packets responsive to determining that the passcode data is valid.
