High-speed reading-writing and mass-storage system under ARM platform and working method of high-speed reading-writing and mass-storage system under ARM platform

Abstract

The invention discloses a high-speed reading-writing and mass-storage system under an ARM platform and a working method of the high-speed reading-writing and mass-storage system under the ARM platform. The high-speed reading-writing and mass-storage system comprises a plurality of distributing main circuits, a serial port service circuit and a plurality of SATA hard disks. The serial port service circuit is connected with the multiple distributing main circuits, and the distributing main circuits are provided with a central processing unit based on an ARM framework. The central processing unit comprises a PCIE interface circuit, an SATA interface circuit and an RGM interface circuit, the PCIE interface circuit is connected with two SATA hard disks through a PCIE-to-SATA bridging circuit, and the SATA interface circuit is connected with two SATA hard disks through an SATA expanding circuit. According to the high-speed reading-writing and mass-storage system, the problem that mass storage can not be achieved due to the fact that multiple hard disks can not be connected under the ARM framework is solved, and the high-speed reading-writing and mass-storage system is completely suitable for the edge service of the CDN, and completely the same as an X86 server in performance; under the same capacity, cost is 70% lower than that of the X86 server, power consumption is 80% lower than that of the X86 server, and the size is 50% smaller than that of the X86 server.

Description

technical field [0001] The present invention relates to data network transmission, in particular to a high-speed read-write and large-capacity storage system and its working method under the ARM platform. The invention and its working method are low power consumption and high performance content distribution network system and its working method. Background technique [0002] The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to publish the content of the website to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the content they need nearby, solve the Internet network congestion situation, and improve The response speed of users accessing website content. The CDN distribution server is a device used by computer terminals to accelerate users' access to content by adding a new layer of network architecture, that is, "edge" serv...

Problems solved by technology

[0003] Traditional CDN server hardware is generally composed of 2-4 INTEL CPUs of X86 architecture, 32G memory, multiple hard disks connected through an array, multiple Gigabit network cards or a 10 Gigabit network card. This kind of prepared server can be used It is suitable for many kinds of software services, but as a CDN service, it can only be used as a CDN distribution function and cannot be applied to other software services. In this way, in a CDN network, having a large number of high-configuration servers greatly wastes servers hardware resources, the construction cost of using such a CDN network is also very high, and the energy consumption of this kind of server is also very high and the volume is large; it is not suitable for the requirements of energy saving and emission reduction advocated by today's society, and it is not suitable for the low Cost requirements, due to the heat dissipation of the X86 server and the complexity of the software, the maintenance of the server is very frequent, which also brings huge pressure to the operation of the CDN network
