Abstract

The invention relates to a backboard cascade system, a backboard number distribution method and computer equipment, the system comprises a server mainboard and N backboards, the server mainboard comprises a connector, and each backboard comprises an uplink connector, a downlink connector and a CPLD; the server mainboard is connected with the first backboard through a connector and is used for transmitting an initial address selection signal to the first backboard; the uplink connector of the ith backplane is connected with the downlink connector of the ith backplane through N signal lines and is used for shifting N-bit address selection signals; the downlink connector of the ith backboard is connected with the uplink connector of the (i + 1) th backboard through N signal lines and is used for transmitting the shifted N-bit address selection signal to the (i + 1) th backboard; and the ith backplane is accessed to the CPLD through m adjacent signal lines between the uplink connector and the downlink connector so as to transmit the number identifier of the ith backplane to the CPLD. By adopting the system, the server mainboard can automatically distribute the number identifier for the backboard.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a backplane cascading system, a method for assigning backplane numbers and computer equipment. Background technique [0002] The backplane design generally needs to meet the following basic functions: support temperature / power consumption monitoring, support hard disk information / real-time status reading, and support hard disk status lighting, and these functions are controlled by BMC (Baseboard Management Controller, Baseboard Management Controller) through I2C (Internet -Integrated Circuit, integrated circuit bus) / I3C (Improved Inter-Integrated Circuit, improved integrated circuit bus) bus transmission data realization. In the current server market, in order to meet the various storage solutions of the server, the server needs to be equipped with multiple backplanes to transfer various hard disks, such as: SAS (Serial Attached SCSI, serial connection small computer ...
