Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, a hard disk backplane compatible with SAS, SATA and NVME hard disks and a design method of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] like figure 1 As shown, the overall structure of the hard disk backplane is a PCB board. The board structure mainly includes: SLIMLINE X8 connector, PIC18F43K22 chip, MINI SAS connector, HDD connector (ports can be increased or decreased according to storage capacity requirements), LED indicators and Power connector.

[0015] The SLIMLINE X8 connector divides the signal into two PCIE X4 and sends them to two HDD connectors respectively. The SLIMLINE X8 connector can meet the demand for higher bandwidth electronic data transmission in compact storage applications. The SAS signal of the MINI SAS connector is respectively sent to the other two HDD connectors; each HDD connector ...

Abstract

The invention discloses a hard disk backplane compatible with SAS, SATA and NVME. The hard disk backplane structure comprises an SLIMLINE X8 connector, four HDD (Hard Disk Drive) connectors and a MINISAS connector, wherein the SLIMLINE X8 connector is divided into two PCIE (Peripheral Component Interface Express) X4 to be respectively connected to two of the HDD connectors; and an SAS signal of the MINI SAS connector is respectively connected to the other two of the HDD connectors. The hard disk backplane further comprises a PIC18F43K22 chip, wherein the PIC18F43K22 chip controls a request ofNVME HDD; the PIC18F43K22 chip comprises a group of SMBUS communicated with a CPU (Central Processing Unit); and the HDD connectors are compatible with the SAS, SATA and PCIE. According to the hard disk backplane disclosed by the invention, the quantity and type of the connectors and supported models can be determined according to product design requirements, the type and quantity of inserted hard disks can be selected according to storage requirements, and the board card size is reasonably designed so as to meet the structural demands.

Description

technical field [0001] The invention relates to the technical field of server hard disk backplane design, in particular to a hard disk backplane compatible with SAS, SATA and NVME hard disks and a design method thereof. technical background [0002] With the rapid development of social informatization, the amount of data is increasing, and the demand for storage capacity and storage flexibility of enterprises is becoming more and more prominent. High-end storage is on paper. PCIE is the latest bus and interface standard. It belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices allocate exclusive channel bandwidth and do not share bus bandwidth. Increased PCIE bus frequency: The data transmission rate of each serial line doubles from 2.5Gbps to 5Gbps, and the bandwidth also doubles accordingly; it can better support future high-end graphics cards, even if the power consumption reaches 225W or 300W, only PCIE alone is neede...
