Description

technical field

[0001] The invention relates to the technical field of backplane design, in particular to a U.2 interface multi-hard disk management backplane and a method thereof. Background technique

[0002] At present, hard disks using the U.2 interface standard have been widely circulated. The U.2 interface is also called SFF-8639. The U.2 interface combines the characteristics of SATA and SAS interfaces. U.2 supports the NVMe protocol and is compatible with SAS, The SATA protocol specification can connect different types of hard disks such as SAS, SATA and NVME. Among them, the interface hard disks of SAS and SATA include both mechanical hard disks (HDD) and solid-state hard disks (SSD), and NVME is a solid-state hard disk based on the NVME protocol.

[0003] For different types of SAS, SATA, and NVME hard disks, their backplane management solutions are often different. For some existing backplanes, SAS and SATA hard disks use the SGPIO management scheme, and NVME hard...
