Abstract

The invention provides a system and method for simply controlling hard disk indicator lamps. The system comprises a server main board and an SATA-NVME hard disk back plate or SAS-NVME hard disk back plate. A logic controller, an SAS controller, an NVME controller and an SATA controller are arranged on the server main board. The logic controller judges the type of a hard disk connected with a harddisk interface. When the hard disk is an SATA hard disk, SGPIO signals sent by the SATA controller are analyzed, and the first hard disk state indicator lamp is controlled; when the hard disk is an NVME hard disk, I2C signals sent by the NVME controller are analyzed, and the first hard disk state indicator lamp is controlled; when the hard disk is an SAS hard disk, SGPIO signals sent by the SAS controller are analyzed, and the second hard disk state indicator lamp is controlled; when the hard disk is an NVME hard disk, I2C signals sent by the NVME controller are analyzed, and the second hard disk state indicator lamp is controlled.

Description

technical field [0001] The invention belongs to the field of server board design, and in particular relates to a simplified system and method for controlling a hard disk indicator light. Background technique [0002] Scalability is one of the important technical indicators of the server, and the scalability of the server requires that the server hardware has good scalability. For a storage array on a server, scalability requires the server to support and be compatible with different hard disk interface standards. For example, it is necessary to support SATA hard disks, SAS hard disks, and NVME hard disks, which are widely used today. In a server system, hard disks of different types need to be mounted under different storage array controllers, and different storage array controllers manage different types of hard disks independently. For example, the SATA controller manages the SATA hard disk, the SAS controller manages the SAS hard disk, and the NVME controller manages th...
