Hard disk module and servo system

Abstract

The invention provides a hard disk module which is suitable for a server. The hard disk module comprises a plurality of hard disk units for storing digital data, a plurality of different peripheral units, a main expansion unit and a plurality of auxiliary expansion units; and each peripheral unit operates in a working state; the main expansion unit comprises a plurality of first and second interface ports respectively and electrically connected with the peripheral units, each auxiliary expansion unit comprises a third interface port and a plurality of fourth interface ports, the third interface ports of the auxiliary expansion units are electrically connected with the second interface ports of the main expansion unit respectively, each fourth interface port of each auxiliary expansion unitis used for being electrically connected with a hard disk unit, and the main expansion unit monitors a working state of each peripheral unit to obtain peripheral information corresponding to the peripheral unit.

Description

technical field [0001] The present invention relates to a storage module and system for digital data, in particular to a storage device in the form of supporting clustered disks, a hard disk module and a servo system with the function of expanding storage capacity. Background technique [0002] With the advancement of network technology, the service traffic of digital information has increased sharply, and the related development of big data has gradually become the mainstream of research in the field of network information. The traditional hardware equipment used for the development of network information related technologies, namely the servo system, uses The number of connected hard disks (JBOD: Just a Bunch of Disks) used to provide information storage is limited, thereby limiting the storage space of digital information, which is obviously not enough to meet the current demand for a large amount of digital information flow. [0003] In addition, as the flow of digital i...

[0002] With the advancement of network technology, the service traffic of digital information has increased sharply, and the related development of big data has gradually become the mainstream of research in the field of network information. The traditional hardware equipment used for the development of network information related technologies, namely the servo system, uses The number of entities that can be connected to the cluster hard disk (JBOD: Just a Bunch of Disks) to provide information storage is limited, thereby limiting the storage space of digital information, which is obviously not enough to meet the current demand for a large amount of digital information flow

[0003] In addition, as the flow of digital information increases, it will further cause the cluster hard disk operation burden of the servo system, and the existing servo system does not have a monitoring mechanism for the cluster hard disk and its related equipment components (such as: operating voltage, operating current, etc.) , if the relevant components fail, the entire servo system will be damaged. Therefore, it is necessary to improve the existing servo system
