Backplane controller for handling two SES sidebands using one SMBUS controller and handler controls blinking of LEDs of drives installed on backplane

摘要

Present disclosure relates to a computer-implemented method for handling two SES sidebands using one SMBUS controller. The method includes one or more of following operations: (a) establishing communication between a backplane controller and a host computer through HBA, (b) receiving control commands and control data from host computer for monitoring and controlling at least one drive of first and second group of drives, (c) determining address and device number of drive to which received control commands and control data are directed, (d) forwarding control commands and control data to first or second SMBUS sideband handler based on address received, (e) controlling the blinking of the LEDs of the drive by first or second SMBUS sideband handler, (f) generating responses by the first or second SMBUS sideband handler, (g) receiving responses by the SMBUS controller, and (h) sending the responses back to the host computer within a predetermined time period.
