Problems solved by technology

[0004] When there are many CPUs in the server, the design method of one CPU to one hard disk is adopted. One CPU has one hard disk, and more hard disks are needed. However, a high-performance server with hundreds of hard disks will make the server bulky and the storage resources excess is unreasonable
However, the design method of using a memory stick instead of a hard disk to connect to the CPU is not only costly, but also resources cannot be allocated flexibly and rationally.
[0005] In addition, ordinary mechanical hard disks are used to build a multi-CPU shared storage system. Due to the long seek time and low speed of mechanical hard disks, it cannot meet the data reading rate requirements of many CPUs.

Embodiment Construction

[0027] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples.

[0028] The inventor noticed during the invention that:

[0029] Currently, there is no multi-CPU shared storage technology in the market, and most high-performance computing fields still adopt the design method of one CPU for one hard disk, so as to balance the gap between the high bandwidth of the CPU and the low access rate of the hard disk. Corresponding technologies such as: RAID controller, PCIe switch expansion hard disk interface. If a server has hundreds of CPUs, according to the existing technology, a CPU with a hard disk needs hundreds of hard disks, and a high-performance server with...

Abstract

The present invention provides a shared storage system and its use method, comprising: a first SATA protocol analysis module receives and analyzes the SATA instructions sent by the CPU; the link arbitration module sends the SATA instructions to the address mapping module one by one; the address mapping module determines The address space indicated in the SATA instruction is NandFlash, and the SATA instruction is sent to the PCIe hard core; after determining that the address space indicated in the SATA instruction is the hard disk, the SATA instruction is sent to the second SATA protocol analysis module. The PCIe hard core encapsulates the SATA command sent by the address mapping module and sends it to the NandFlash controller; the second SATA protocol analysis module encapsulates the SATA command sent by the address mapping module and sends it to the hard disk. The invention realizes reasonable heterogeneity of storage bodies and reasonable allocation of storage resources.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a shared storage system and a method for using the same. Background technique [0002] There is no technology for multiple CPUs to share storage in the prior art. Most high-performance computing fields still adopt the design method of one CPU to one hard disk, or use a memory module instead of a hard disk to connect to the CPU. [0003] The deficiencies of prior art are: [0004] When there are many CPUs in the server, the design method of one CPU to one hard disk is adopted. One CPU has one hard disk, and more hard disks are needed. However, a high-performance server with hundreds of hard disks will make the server bulky and the storage resources Excess is unreasonable. However, the design method of using a memory stick instead of a hard disk to connect to the CPU is not only costly, but also resources cannot be allocated flexibly and rationally. [0005] In addition, ordi...
