According to the present invention a method and a system is provided for operating a storage area network in a server environment in which multiple servers share one Fibre Channel adapter. One such apparatus can include an anode and a showerhead body. A controller provides for incrementing or decrementing the tap delay of both delay modules to assure clock data falls at the center of the monitoring window as determined using the monitor delay module. A lifespan for the password is selected based on the assigned relative security level of security. If there is no match then the locations of the non-matching expressive facial feature in the captured image are stored. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
