Disc array system for long-term data storage

Abstract

The invention discloses a disc array system for long-term data storage, and aims to provide a disc array system for long-term data storage which does not damage the disc or cause data leak and loss. The system comprises a completely sealed shell (111), a plurality of discs (12), a controller (16), a plurality of LED indicating lamps (11); the plurality of discs (12) and the controller (16) are arranged inside the shell (111), a shock-proof device is arranged between the shell (111) and the discs (12); the interior of the shell (111) is filled with inert gas; the controller (16) comprises a central processing unit (61), a random access memory (68), a flash memory (69), a configurable hardware circuit (611), an LED control unit, a temperature sensing unit, an external disc interface controlunit, a network control unit, a disc control unit and a PCI bus. The invention is widely applied in the field of disc array system for long-term data storage.

Description

technical field [0001] The present invention relates to a disk array system for long-term data storage. Background technique [0002] With the continuous expansion of computer application fields, users have higher and higher requirements for storage system capacity, reliability and availability, and faster speed. Aiming at the challenges faced by the storage system, people thought of using multiple disk drives to form a RAID (Redundant Array of Independent Disk) disk array to obtain high data transfer rate and large storage capacity. Because disk arrays have the advantages of relatively low price, fast access speed, and random access, disk arrays have a large number of applications in the field of online data storage and data backup. However, in the field of long-term offline data storage (several years to decades), ordinary disks or disk arrays have not been widely used due to the following shortcomings: 1. For long-term storage of data on the disk, keep the disk powered o...

AI Technical Summary

Problems solved by technology

However, in the field of long-term offline data storage (several years to decades), ordinary disks or disk arrays have not been widely used due to the following shortcomings: 1. For long-term storage of data on the disk, keep the disk powered on for a long time Power-hungry and can cause a disk to fail and have to be replaced in a relatively short amount of time

2. Disks stored offline for a long time are susceptible to data loss due to external factors (such as magnetic fields or electric shocks), or disk damage due to internal factors (such as the deposition of bearing oil or the aging of the mechanical arm)

3. Moisture and air oxidation can easily cause damage to the components on the disk exposed to the air for a long time, resulting in damage to the disk

4. Collision or external extrusion can easily cause disk damage

5. Static shock can easily lead to disk damage

6. The ordinary disk itself is a rewritable medium

Bare disks can be easily read or written by unauthorized persons leading to data leakage or loss
