Embodiment 1

[0035] This embodiment provides a method for expanding the storage capacity of a hard disk, such as figure 1 shown, including the following steps:

[0036] S11. In a system that supports hotplug, the CPU has several PCIE interfaces. The CPU connects the four PCIE interfaces to several NVME hard disks through the PCIE protocol. Several NVME hard disks are connected in parallel and set as a group of NVME hard disks. Through this This method realizes the four-way PCIE interface corresponding to multiple hard disks, completes signal transmission, and increases the connection efficiency of the line;

[0037] The number of NVME hard drives is at least one, and can be 1, 2, 3, etc.;

[0038] In the choice of NVME hard disk power supply mode, CPLD controls EFUSE to power on and off. One NVME hard disk is connected to one EFUSE, and the EFUSEs of a group of NVME hard disks are connected to the same power supply. EFUSE is controlled by CPLD, so CPLD controls the power supply of each NV...

Embodiment 2

[0055] This embodiment provides a method for expanding the storage capacity of a hard disk, such as image 3 shown, including the following steps:

[0056] S21. In a system that supports hotplug, the PCH is equipped with several SATA interfaces, and the PCH connects the SATA of each interface to several SATA hard disks through the SATA protocol, and several SATA hard disks are connected in parallel to each other. In this way, one SATA interface is realized. Connect multiple hard disks, and set the multiple SATA hard disks connected to one SATA interface as a group of SATA hard disks, which increases the connection efficiency of the line;

[0057] The number of SATA hard drives is at least one, and can be 1, 2, 3, etc.;

[0058] In the selection of SATA power supply mode, EFUSE is controlled by CPLD to perform power-on and power-off operations. One SATA hard disk is connected to one EFUSE, and the EFUSE of each group of SATA hard disks is connected to the same power supply. EF...

Abstract

The invention discloses a method for expanding the storage capacity of a hard disk, comprising the following steps: a CPLD reads hard disk in-place information and sends the hard disk in-place information to a BMC, an OS reads the BMC hard disk in-place information through a PCH to generate a hard disk in-place list, when a CPU reads and writes the hard disk, the CPU interacts with the in-place hard disk, and the OS controls the CPU to disconnect with the in-place hard diskwhen the CPU needs to be switched to be connected with the target hard disk; after the CPLD is controlled to stop supplying power to the in-place hard disk, the OS controls the load programmable logic device to supply power to the target hard disk and controls the CPU to be connected with the target hard disk according to the in-place list of the hard disk. In this way, expansion of the capacity of the hard disk can be completed under the condition that an expansion card is not added, and hard disk switching can be remotely conducted; and power failure is not needed when the hard disks are switched, so that the overall power consumption is reduced.

Description

technical field [0001] The invention relates to the field of storage expansion, in particular to a method, system and medium for expanding the storage capacity of a hard disk. Background technique [0002] With the continuous development of cloud computing, more and more Internet operators use high-density type storage servers. The design of this kind of server is characterized by high hard disk density and large hard disk capacity of the whole machine. This kind of high-density storage is often used for data archiving, long-term backup of pictures and videos, etc. [0003] In order to ensure large-capacity hard disk storage, the hard disk often needs an external SAS (statistical analysis system, statistical analysis system) card, RAID (redundant array of independent disks, redundant array of independent disks) card, expander (expander) card to expand the hard disk capacity. Using this method to ensure the performance requirements after hard disk expansion can expand the st...
