A Nearline Disk Array Library with Contact Areas on Both Sides

Abstract

The invention discloses a near-line magnetic disk array library with contact areas at two sides. The near-line magnetic disk array library comprises an all-independent driver set, a plurality of mechanical arms, a controller, and a data management server. The all-independent driver set consists of a plurality of magnetic disk array module groups arranged in M rows and N columns; the front ends andthe rear ends of the plurality of magnetic disk array module groups are arranged externally; first contact areas are arranged at the front ends of the plurality of magnetic disk array module groups;second contact areas are arranged at the rear ends of the plurality of magnetic disk array module groups; contact points are arranged in the first contact areas and the second contact areas; the firstcontact area at each row or each column corresponds to one mechanical arm; and the second contact area at each row or each column corresponds to one mechanical arm. The controller is used for controlling movement of the mechanical arm to a designated position and realizing connection between the data management server and the magnetic disk array module groups to complete data transmission. The near-line magnetic disk array library has advantages of high stability and low energy consumption; reading and writing on the independent disc drivers are carried out simultaneously; and the data are obtained conveniently.

Description

technical field [0001] The invention relates to the technical field of storage systems, in particular to a near-line disk array library with contact areas on both sides. Background technique [0002] The process of digitization generates a large amount of data storage requirements, a considerable part of which comes from sensors, especially image sensors. Video surveillance is a typical application of image sensors, and its workflow can be divided into two parts, one is to record the video data stream continuously and sequentially without interruption; the other is to call the recorded video. Since the recalled operation is random and triggered by external emergencies, the data access process of video surveillance has the characteristics of "sequential write, random read". Among them, sequential writing is an uninterrupted continuous process, and random reading does not happen frequently, and is an operation of randomly calling data in a time window of the recorded time ser...
