Problems solved by technology

[0005] 1) The existing Raid storage form will inevitably occupy more disk slots, so that the actual application of the storage server will be reduced, which will greatly reduce the application of the server;
[0006] 2) The current application of the U.2 interface protocol has greatly increased the read / write rate of the hard disk and the storage capacity has also increased, but the storage devices that support the U.2 interface are limited to NVME hard disks at present, the storage device is single, and the cost remains high
[0007] In order to solve the problem of high cost of key data Raid, the present application invented a PCIE storage device based on U.2 interface to support self-Raid function

Embodiment Construction

[0016] The present application invents a PCIE storage device that supports the Raid function based on the U.2 interface. This device distinguishes independent storage unit devices inside a single storage unit body, and passes through the SCSI on the Controller (SCSI / RAID Host Controller motherboard / array card) Hard disk / array controller) realizes self-Raid within a single storage device, which can greatly reduce maintenance costs while ensuring sufficient data security.

[0017] The specific implementation steps of the automated testing described in the present invention will be described below through an embodiment.

[0018] attached figure 1 Shown is a 3.5-inch HDD. The present invention is based on the physical space position of the 3.5-inch HDD. The independent storage units are interconnected through the Switch chip and connected to the outside through the U.2 interface. The physical diagram after connection is shown in the attached figure 2 shown. The present inventio...

Abstract

The invention provides a PCIE storage device supporting a self-Raid function based on a U.2 interface. Through integrated design of a storage unit, a Switch chip is used to interconnect independent storage units, and the independent storage units are interconnected with the external. The device can solve problems of occupying excessive drives under a Raid environment and cost rising caused by single U.2 interface device. The device makes a production maintenance link simplified, improves application of a server, and effectively controls cost.

Description

technical field [0001] The invention relates to the field of hard disk testing, in particular to a PCIE storage device supporting a self-Raid function based on a U.2 interface. Background technique [0002] With the development of cloud computing big data industry, the security of data system is becoming more and more important. Therefore, as the main storage unit of data, the development of storage devices is more diversified. How to increase the access speed of the disk, how to prevent data from being lost due to disk failure and how to effectively use the disk space has always been a problem for computer professionals and users. However, the price of large-capacity disks is very expensive, which has caused great harm to users. burden. The emergence of disk array technology has solved these problems in one fell swoop. However, at present, storage devices of various protocols have a certain failure rate. In order to meet data security, Raid processing will be performed o...
