Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For ease of understanding, a brief description of the relevant knowledge referred to herein follows.
Hard disks are one of the core components of computer storage and are classified in a variety of ways, with knowledge of these classifications being better able to manage and use the storage device. The classification of hard disks is as follows:
1. classifying according to interface types:
Mechanical hard disks, i.e., conventional hard disk drives (HDD, hard Disk Drive), are types of hard disks based on the principle of magnetic storage. HDDs are typically interfaced using SATA (SERIAL ATA, serial ATA interface hard disk), a type of computer bus interface for interfacing the motherboard with the storage device. The HDD is characterized by large capacity, low price, but relatively slow speed, and is suitable for large capacity data storage requirements.
Solid state disk (SSD, solid STATE DRIVES) is a storage device based on flash technology that stores data much faster than HDDs. SSDs can be further categorized according to interface and protocol:
SATA SSDs use SATA interfaces that are relatively slow in transfer speed, but still much faster than conventional HDDs. SATA SSDs are typically the upgrade of choice for older systems.
NVME (Non-Volatile Memory Express, nonvolatile memory host controller interface) SSD is one of the fastest solid state disk types at present. The data processing device uses PCIE (Peripheral Component Interconnect Express) interfaces to directly communicate with a CPU (Central Processing Unit, a central processing unit), the transmission speed can reach 32Gbps, the data reading and writing performance is greatly improved, and the data processing device is very suitable for application scenes with high requirements on speed.
2. Sorting by storage medium:
The mechanical hard disk adopts a mechanical turntable and a magnetic head to read and write data, so that the speed is limited by mechanical movement. Nevertheless, HDDs still have an unparalleled price advantage over mass data storage.
The solid state disk does not contain any mechanical parts, and the semiconductor memory chip is completely used for data storage, so that the read-write speed is extremely high, and the shock resistance is excellent. SSDs can be further classified into SLC (Single-LEVEL CELL, single layer Unit), MLC (Multi-LEVEL CELL, multi-layer Unit), TLC (Triple-LEVEL CELL, triple-layer Unit) and QLC (Quad-LEVEL CELL, four-layer Unit) depending on the flash memory chips. Typically, SLC has the longest life but the highest cost, and QLC has the highest storage density but a relatively short life.
SATA and SAS (SERIAL ATTACHED SCSI ) hard disk management based on RAID (Redundant Arrays of INDEPENDENT DISKS, disk array) cards currently exist. In general, a RAID card driver has management of a hard disk positioning lamp, management of a hard disk device failure, and lighting of a failure indication lamp. Indicator lights of a hard disk (NVME of a PCIE interface directly connected to a CPU) managed by a current RAID card generally have three states of a positioning light blue, a fault red, and a rebuild (reset) state yellow. The display state of the indicator lamp is not easy to be found when being monitored. Usually, shell script is used for lighting the indicator lights and checking the status of the indicator lights on the NVME hard disk, and the characters are colored to make the user clear at a glance. However, the method is improved only on the display of the indicator lamp, no indicator lamp can display the real-time health state of the hard disk, and the red color is displayed only after the hard disk is completely failed, so that the method is not beneficial to preventive replacement and maintenance in the field of the data center.
Therefore, the application provides a hard disk state monitoring scheme of the equipment system, which can visually display the health states of the hard disks, and each health state of the hard disk has a corresponding color display, so that the equipment abnormality can be conveniently identified by on-site operation and maintenance personnel of a data center.

Each hard disk connection structure corresponds to a respective communication transmission link, and the central processing unit and the baseboard management controller (BMC, baseboard Management Controller) can directly or indirectly obtain the health status information of the hard disk through the corresponding communication transmission links.
In a specific embodiment, the health status information of the hard disk may be obtained through SMART information. The SMART information includes a plurality of attributes, each of which describes a particular aspect of the hard disk, the attribute values of which are generally closely related to the health of the hard disk, and when a potential problem occurs in the hard disk, the SMART information gives an alarm in advance to help the user take measures in time.
In the embodiment of the application, the multi-mode state table of the preset indicator lamp with corresponding relation and the display state information is constructed in advance according to different health state information. That is, the information of the display color of the indicator light device corresponding to the hard disk in a certain health state is recorded in the preset indicator light multi-mode state table. The display state information corresponds to the display color of the indicator light device under the condition of the current health state information of the hard disk, and each health state information of the hard disk is displayed with the corresponding color.
And after the display state information of the corresponding indicator lamp device is matched from the preset indicator lamp multi-mode state table according to the acquired health state information of the hard disk, performing color display control on the indicator lamp device according to the display state information. Because each health status information of the hard disk has the corresponding color display, the health status of the hard disk can be judged through the display color of the indicator light device, and the abnormal equipment can be processed and replaced in advance before the hard disk equipment is completely failed, so that the probability of downtime of the data center server is reduced.
The application provides an equipment system, which comprises an equipment main board and a hard disk backboard, wherein a central processing unit and a substrate management controller are arranged on the equipment main board, an indicator lamp device and hard disks with different interface standards are arranged on the hard disk backboard, the equipment system adopts any one of a plurality of preset hard disk connection structures, the central processing unit and the substrate management controller are respectively connected with the hard disks to establish communication transmission links, the substrate management controller is connected with the indicator lamp device and is used for acquiring health state information of the hard disks through the communication transmission links in any one of the hard disk connection structures, and color display control is carried out on the indicator lamp device based on display state information of the indicator lamp device corresponding to the health state information matched from a preset indicator lamp multi-mode state table so as to judge the health state of the hard disks through the display color of the indicator lamp device, and the preset indicator lamp multi-mode state table is used for recording the corresponding relation between different health state information and different display state information.

In a specific embodiment, regarding improvement of hardware, a Light-Emitting Diode (LED) chip adopting a single-wire return-to-zero communication mechanism is disposed in the indicator Light device, and brightness of each color on three primary color channels of the LED chip corresponds to different levels, so as to complete full-true color display.
For example, the indicator light element can use a WS2812B tricolor LED chip, the LED chip can realize 256-level brightness display, and the full true color display characteristic of 16777216 colors is realized, so that the indicator light element can be used for performing multifunctional positioning on the hard disk, namely positioning the hard disk and visually displaying the health state.
It should be noted that a second General-purpose input/output (GPIO) port of the BMC is connected to the device motherboard through a third General-purpose input/output port of the target connection terminal. Fig. 2 is a schematic circuit diagram of a hard disk connected with an LED chip, where P1 is a target connection terminal on a device motherboard, pin 1 in P1 is connected with a GPIO of a BMC, and Data information is sent to the BMC through a Data GPIO of the connection terminal P1.

Fig. 3 shows a schematic diagram of a data transmission process of the LED chip. Wherein D1 is data sent by MCU (Microcontroller Unit, micro control unit) end, D2, D3, D4 are data automatically shaped and forwarded by cascade circuit. Wherein the cascading of circuits, the process includes connecting the output of one circuit to the input of another circuit to form a continuous operational relationship. This cascading is accomplished by connecting an output port in one circuit with an input port in another circuit. The current is supplied next to each other, and a first signal (24 bits) is supplied to the first LED and then a second signal (24 bits) is supplied to the second LED.

And the corresponding relation between different health state information and different display state information is recorded in the multi-mode state table of the preset indicator lamp.
Table 1 Multi-modal state table of preset indicators
It should be noted that, in a specific actual operation, the hard disk state information corresponding to the required color may be changed according to the requirement by the code, and the color corresponding to the required hard disk state information may also be changed. For example, the color of the indicator light corresponding to the health status information of the "hard disk in health status" may be changed to blue through the code, or the hard disk status information corresponding to the display status information of the "green" may be changed to be positioned on through the code.
Specifically, the baseboard management controller is further configured to adjust an object code to change display state information corresponding to different health state information and/or health state information corresponding to different display state information, where the object code is a code for configuring the multi-mode state table of the preset indicator lamp.
In addition, to avoid that too many indicator light colors cause difficulty in finding and distinguishing, the same indicator light colors may be set for different kinds of certain faults. Therefore, when the display color of the indicator lamp is corresponding, the current type of faults are determined according to the display color, and then the fault type is determined by subdivision, so that the comparison searching time is saved, and meanwhile, the display color of the indicator lamp device can be distinguished more easily to a certain extent.

When smartctl is used, a device path is specified, for example smartctl-a/dev/sda (sda is the drive letter of a certain sata hard disk).

And the BMC displays the multi-mode display state information according to the health state information of the SATA hard disk.
