Abstract: Systems and methods presented herein provide for tunneling PCIe data through a SAS domain. a data system includes a SAS expander, a PCIe target device coupled to the expander, and a SAS controller communicatively coupled to a host system and the expander. The controller is operable to open a connection with the expander via the SAS protocol, and to transport packet data between the target device and the host system through the connection via the PCIe protocol. For example, the controller and the expander may be operable to buffer packets of data in the connection. The controller may issue a number of the data packets to be transferred in the connection. Then, the issued number of data packets are transported between the target device and the host system through the connection via the PCIe protocol.

Abstract: The present invention relates to a method for implementing an address mapping scheme within a serial attached SCSI enabled storage area network environment comprising respectively assigning a world wide name of each device comprised within a storage area network to a plurality of switch ports that are comprised within a serial attached SCSI (SAS) switch that is comprised within the storage area network, and assigning each port comprised within the SAS switch to a zone grouping. Further, the respective world wide names of each device that each world wide name will have the right to access is determined, and thereafter a SAS zone permissions table is built comprising the world wide names of each device that each world wide names has the right to access. The world wide names, the SAS switch port assignments, and the SAS zone permission tables are saved to a file or database.
