Description
Technical Field
The invention belongs to the field of server testing of a whole cabinet, and particularly relates to a control system of a standard solid state disk state indicator lamp of a nonvolatile memory.
Background
Complex Programmable Logic Device, NVMe: Non-Volume Memory express nonvolatile Memory standard, VMD Volume Management Device, SSD Solid State drive Solid State disk, POST: power On Self Test, BIOS Basic Input/Output System, GPIO General Purpose Input/Output, SMBus System Management Bus.
Unlike traditional SAS and SATA protocols, NVMe (Non-Volatile Memory express) is a set of standardized protocols and commands based on PCIe bus, and has characteristics of high IOPS, low latency, low power consumption, and the like.
The NVMe is an extensible storage application protocol, and can fully exert the performance of the PCIe solid state disk, so that the application requirements of various scenes such as enterprise level, data center and consumption level are better met.
The NVMe solid state disk is widely designed and applied to an Intel Purley platform, and is different from SAS/SATA which has mature and complete hard disk indicator lamp management specifications. The state of the hard disk indicator lamp of the NVMe solid state disk is uniformly managed by the VMD storage driver of Intel when the VMD is started. And when the VMD is closed, the VMD is controlled by the BIOS and the drive of the operating system.
In the latter case, the actual appearance of the hard disk light is not uniform when the VMD is off. For example, under different operating systems, the hard disk indicator lamp shows different behaviors, and the hard disk indicator lamp does not conform to the actual state of the hard disk.
Under the condition that the VMD is closed, the hard disk indicator lamp of the NVMe solid state disk is controlled by a default value set by the BIOS in the BIOS power-on self-test stage, but after the operating system driver takes over the control right, the state of the hard disk indicator lamp is relatively disordered due to the fact that no VMD driver is uniformly managed.
The state representation of the hard disk state indicator lamp is different under different operating systems such as Windows and Linux, or the representation of the hard disk state indicator lamp is not accordant with the actual state of the hard disk. Although the problem of data transmission failure or system stability cannot be caused, the user may be disturbed or even misled to judge the state of the hard disk, and the user experience is influenced.
As shown in fig. 1, the complex programmable logic device CPLD 1 does not determine the state of the volume manager VMD of the system, and analyzes all information sent to the CPLD by the central processing unit CPU and directly outputs the information to drive the hard disk state indicator 4, so that when the volume manager VMD is turned off, the hard disk state indicator shows different states under different operating systems, or the hard disk state indicator does not represent the actual hard disk state, which causes a user to be confused or even misled in the judgment of the user.
This is a deficiency of the prior art, and therefore, in view of the above-mentioned disadvantages in the prior art, it is very necessary to provide a control system for a standard solid state hard disk status indicator lamp of a nonvolatile memory.
Disclosure of Invention

In order to achieve the purpose, the invention provides the following technical scheme:
a control system of a standard solid state hard disk state indicator lamp of a nonvolatile memory comprises a Complex Programmable Logic Device (CPLD), wherein the Complex Programmable Logic Device (CPLD) is connected with a Central Processing Unit (CPU), a hard disk state indicator lamp and a south bridge chip (PCH);
the complex programmable logic device CPLD is used for judging whether the volume manager VMD is in an open state or a closed state according to the information sent by the south bridge chip PCH;
the complex programmable logic device CPLD is also used for controlling the state of the hard disk state indicator lamp when the volume manager VMD is in a closed state.
Furthermore, the complex programmable logic device CPLD is also configured to directly analyze information sent by the central processing unit CPU when the volume manager VMD is in an open state, and the analyzed information drives the hard disk state indicator light.
Further, the complex programmable logic device CPLD directly resolves the information of the I2C protocol sent by the central processing unit CPU.
Further, the hard disk status indicator lamp comprises a hard disk error status indicator lamp and a hard disk in-place status indicator lamp.
Further, when the volume manager VMD is in the off state, the complex programmable logic device CPLD raises the hard disk error state indicator light and the hard disk in-place state indicator light to control the hard disk error state indicator light and the hard disk in-place state indicator light to be in the non-lighting state.
Further, the complex programmable logic device CPLD is connected with the central processing unit CPU through a system management bus SMBUS.
Further, the south bridge chip PCH is connected to the complex programmable logic device CPLD via a general purpose input/output port GPIO.
Further, the south bridge chip PCH is connected to the complex programmable logic device CPLD via a newly added or reserved GPIO.
When the volume manager VMD is in an open state in the setting of the basic input output system BIOS, the basic input output system BIOS sets the general purpose input output port GPIO high; when the volume manager VMD is in the off state in the setting of the basic input output system BIOS, the basic input output system BIOS sets the general purpose input output port GPIO to be low. And the complex programmable logic device CPLD judges whether the volume manager VMD is opened or not according to the state of the general input/output port GPIO.
The invention has the beneficial effects that: on the premise of not increasing the cost, the complex programmable logic device CPLD directly controls the state of the hard disk state indicator lamp through a simple and easy software and hardware design mode under the condition that the volume manager VMD is turned off, so that the management of the hard disk state indicator lamp is unified, the user experience can be improved, and the product image and the competitiveness are improved.
In addition, the invention has reliable design principle, simple structure and very wide application prospect.
Therefore, compared with the prior art, the invention has prominent substantive features and remarkable progress, and the beneficial effects of the implementation are also obvious.
