CN105096991A - Design of an indicating light capable of rapidly and directly checking the state of a hard disk - Google Patents

Abstract

The invention provides a design of indicating lights capable of rapidly and directly checking the state of a hard disk. The design comprises a hard disk group, an expander, a microcontroller CPLD on a back plate and an indicating light circuit on a front plate. The CPLD is used for analyzing; the orders of the hard disks correspond; the position of the indicating light on the front plate corresponds to the position of a hard disk in a storage system. The colors to show different faults are also regulated. For instance, if the hard disk is in normal operation, the color turns green; if no hard disk is detected, the light is not on; if the hard disk develops a fault, the color turns red. All colors showing the faults are regulated by CPLD. According to the invention, an indicating light capable of rapidly and directly checking the state of a hard disk is provided. In comparison with the prior art, a user can use the indicating light to monitor the state of a hard disk with his or her naked eyes at any time, freeing them from using other tools to do so. The user can therefore, check from the front plate the positioning state of a hard disk and through the indicating light, finds the hard disk in fault and the position of the hard disk. Consequently, a hard disk in fault can be changed rapidly and in time, and therefore, risks caused by the fault of a hard disk can be reduced and business can be resumed shortly.

Description

The pilot lamp design of disk state is checked in a kind of quicklook

Technical field

The present invention relates to storage hardware field, the pilot lamp design of disk state is checked in specifically a kind of quicklook.

Background technology

Be engaged in storage hardware design; particularly when front panel design; we can find to store front panel design pattern, kind is a lot; no matter be design and the protection in later stage in early stage, we can add corresponding hard disk Position Design when design usually, prevent the factor of many and diverse influences hard disk failure from affecting; cause hard disk failure; data can be caused to write to system, business stops the situation of machine of even delaying, and can have an impact to business.Once our hard disk breaks down, no matter be due to hardware reason or software reason, all can cause larger impact to system, need to change recovery in time.

After hard disk breaks down, location, hard disk position, replacing construction, release time are very important, at present in general design, disk chassis all has front panel, whether hard disk breaks down, and front panel cannot intuitively be found out, must first be opened by front panel, and then find out the position of faulty hard disk, so comparatively lose time.The present invention invents one intuitively can find out on front panel which block hard disk concrete breaks down.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, the pilot lamp design providing a kind of quicklook to check disk state.

Technical scheme of the present invention realizes in the following manner, its structure is by hard disk groups, expansion EXPANDER, backboard single-chip microcomputer CPLD and front panel indicator light circuit plate are formed, CPLD is used for resolving, and hard disk order is corresponding, and front panel pilot lamp position is corresponding with storage system hard disk position, color during the regulation various state of fault, green time as normal in hard disk, do not have not work during hard disk, red during hard disk failure; All use CPLD regulation;

When the hard disk in storage system breaks down, signal can be sent to CPLD by trigger Extensible EXPANDER, pilot lamp shiny red corresponding with it on the front panel that CPLD defines before triggering.

Advantage of the present invention is:

Compared to the prior art a kind of quicklook of the present invention checks the pilot lamp design of disk state, and the disk state of naked eyes monitoring at any time, need not by other instrument; Intuitively can check that hard disk positioning states pilot lamp intuitively shows faulty hard disk and position from front panel; Hard disk can be changed fast, in time, reduce the risk that hard disk failure brings, fast quick-recovery business.

Accompanying drawing explanation

Fig. 1 is the pilot lamp designed system topology that disk state is checked in a kind of quicklook.

Embodiment

Below in conjunction with accompanying drawing, a kind of quicklook of the present invention is checked that the pilot lamp design of disk state is described in detail below.

As shown in Figure 1, the pilot lamp design of disk state is checked in a kind of quicklook of the present invention, its structure is made up of hard disk groups, expansion EXPANDER, backboard single-chip microcomputer CPLD and front panel indicator light circuit plate, and CPLD is used for resolving, hard disk order is corresponding, front panel pilot lamp position is corresponding with storage system hard disk position, color during regulation various state of fault, green time as normal in hard disk, do not have not work during hard disk, red during hard disk failure; All use CPLD regulation;

When the hard disk in storage system breaks down, signal can be sent to CPLD by trigger Extensible EXPANDER, pilot lamp shiny red corresponding with it on the front panel that CPLD defines before triggering.

This patent provides the pilot lamp design that disk state is checked in a kind of quicklook.The idea of the design breaks original design concept utilizing storage management software interface to check hardware state, and adopt new idea: disk state locating and monitoring is placed on storage panel and realizes, so more easily check the state of all hard disks of storage array more intuitively, (not needing to enter into storage management software), utilize expansion EXPANDER, send to the single-chip microcomputer CPLD of backboard, control the circuit of front panel hard disk indication lamp with this.

It is very simple and convenient that a kind of quicklook of the present invention checks that the pilot lamp of disk state designs its processing and fabricating, can process to specifications shown in accompanying drawing.

Except the technical characteristic described in instructions, be the known technology of those skilled in the art.
