Abstract

The invention discloses an SAS hard disk and NVMe hard disk compatible hard disk backplane, and relates to the field of server hard disk backplanes. The integral structure of the hard disk backplane is a PCB board card on which a plurality of hard disk connectors and a CPLD are arranged, the hard disk connectors are SAS hard disk and NVMe hard disk compatible connectors, and are connected to the CPLD; and the CPLD can be used for automatically recognizing the types of connected hard disks, and is in communication with a BMC management module on a server mainboard through an I2C bus. According to the SAS hard disk and NVMe hard disk compatible hard disk backplane, an SAS hard disk and an NVMe hard disk use a same onboard connector and are compatible, so that the online change of the two hard disks is realized, the operation convenience is improved and the board card development cost is reduced; the management, carried out by the BMC management module, on the hard disk operation states and health conditions is realized; and by using different combinations of LED lamps, the current hard disk states are shown, so that convenience and visualization are provided.

Description

technical field [0001] The invention relates to the field of server hard board backplanes, in particular to a hard disk backplane compatible with SAS hard disks and NVMe hard disks. Background technique [0002] SAS (Serial Attached SCSI) hard disk is a serially connected SCSI hard disk. Compared with SATA hard disk, SAS hard disk can significantly improve the storage performance of the device. Due to its excellent availability and expandability, it has become the most widely used hard disk in server-level equipment. type. NVMe (Non-Volatile Memory Express) hard disk is a non-volatile memory hard disk, which is a specification of SSD using PCIe channel. Due to the ultra-high transmission speed of PCIe x4, the performance of NVMe hard disk has been greatly improved compared with SAS hard disk, which is the development direction of server hard disk in the future. Due to the high cost of NVMe hard disks, the application is not yet widespread. However, as the technology matur...
