Different hard disk types have respective product advantages, and computer product designers need to select by combining performance and cost. As market demands are diversified, the design demands and the day by consumers for being compatible with different hard disk types are greatly increased.

Step 102: the controller is communicated with a HOST HOST end, so that the HOST HOST end identifies the corresponding hard disk type by identifying the state of the corresponding input/output (IO) pin, and switches different hard disk types to configure and test the hard disk equipment of the corresponding type.
For example, the grounds P10 and P4 in the corresponding IO pins are set to GND, and E6 is set to Open, at this time, the hard disk module is of an SAS/SATA type; wherein, SATA/SAS is serial hard disk and serial SCSI hard disk.
P10 and E6 are set to Open, P4 is set to GND, and the hard disk drive is in a Quad PCIE (NVME) type state. Wherein the NVME is a nonvolatile memory standard hard disk.

The SFF committee promulgates a number of standards in tandem indicating that the 8639 connector can be compatible with a number of types of memory devices, and the identification of the memory devices is determined by the corresponding pin levels. The protocol specification is as shown in the following table:
PRSNT# | IfDet# | IfDet2# | |
P10 | P4 | E6 | Device Type Installed |
Gnd | Gnd | Open | SAS/SATA |
Gnd | Open | Open | Undefined |
Open | Gnd | Open | Quad PCIe |
Open | Open | Open | Bay Empty |

The voltage required by the CPLD is 3.3V, and 3.3V can be directly led out from a pin E3 to supply power for the CPLD. However, in order to ensure the normal function of the CPLD during the larger power consumption, the embodiment of the invention selects 12V as the dc DCDC voltage reduction circuit to provide a power supply scheme for the CPLD. Because 12V has 3 power supply pin feet to supply power, the device can support larger power consumption. The schematic diagram of the CPLD circuit is shown in fig. 3:

The CPLD end of the hard disk mold can realize communication with the HOST end only by being configured to correspond to the I2C Controller.
The hard disk configuration IO pin comprises: the SFF-8639 protocol specifies that P10/P4/E6 sets pins for Device Type (Device Type), and the pin states are GND and Open. The CPLD has rich General-purpose input/output (GPIO) resources, and three pins are selected to respectively and correspondingly control the pin states. In order to facilitate the pin control of the CPLD and avoid the influence of IO configuration inside the CPLD on the pin configuration, the CMOS is selected for isolation and comprises the CMOS1, the CMOS2 and the CMOS3, when the CPLD outputs high level, the CMOS is conducted, and a corresponding pin of the connector is grounded; when the CPLD outputs low level, the CMOS is closed, and the corresponding pin of the connector is in an OPEN state.
