Description

The Monitering Method of Disks in RAID System

The present invention relates to RAID (Redundant Array of Inexpensive Disks), a device for data security, and monitors the state of each disk in real time when RAID is configured with a plurality of hard disk drives (HDDs) or solid state drives (SSDs). To check and monitor directly with the human eye.

There are a plurality of recording methods in RAID, whereby the purpose and the storage capacity which can be saved are different, and "RAID 0 (striping)" and "RAID 1 (mirroring) are often used in a general PC.

Among them, RAID 0 aims to speed up data, and reading and writing is speeded up by distributing and writing different data to a plurality of HDDs. On the other hand, since the data is distributed, even if one HDD fails, it cannot be read.

On the other hand, the purpose of data protection is RAID 1, which records the same data on a plurality of HDDs and improves the stability of the data. Even if one HDD fails, data remains on the other HDD, making data recovery easier. The speed of reading and writing is basically the same as that of the HDD group. However, since the same contents are repeatedly recorded, the available storage capacity is half of the total.

RAID 5 requires at least three physical HDDs. In this method, parity information is distributed and stored in all HDDs without having a dedicated HDD for storing the parity information. Also, this method does not slow down because it scatters and stores information, but it has a downside when reading. Even if one HDD is physically damaged, the parity value is tracked in reverse, allowing for perfect recovery.

Control systems in industrial equipment such as semiconductors, LCDs, LEDs, and solar cells have lost productivity due to the failure of the HDD or SSD, which is the storage medium of DATA, over time. RAID has the advantage of solving this problem.

However, if a disk fails and the status of the disk is not properly informed to the user and left unchecked, the RAID itself becomes useless.

Therefore, there is an urgent need for a device to check the disk status in various ways, and when there is no user response by judging whether the user is actively coping with the problem and an alarm system that notifies when a problem that requires attention occurs. There is an urgent need for a function to notify the alarm again at regular time intervals.

The present invention intends to apply to a RAID system using a monitoring method by a visual alarm generator of the GUI according to the user response and a method of displaying the LED on each disk.

The present invention relates to a disk monitoring system having a function of displaying on a disk as well as visual monitoring in a GUI when a problem occurs in an HDD or SSD in a RAID configuration of an industrial equipment control PC.

In RAID, if one disk fails, all control systems on the other continue. However, there is a case where the disk status is not known and it is left unattended. In the Windows environment, the S / W function displays the disk information and status in real time on the monitor and keeps the operator informed at regular intervals. It not only informs the status of the star by LED lamp but also shows the disk failure and status, so it always checks the status of RAID. When it is determined that the response is insufficient, the warning screen activates the pop-up window at regular time intervals to maintain the RAID status from operator change or inadvertent response.

The present invention is a device that displays the status of the disk for each disk and the S / W to detect the status of the disk in the RAID system and the alarm function to inform the alarm repeatedly in the GUI at regular time intervals when a problem occurs Consists of.

As shown in FIG. 5, an alarm is generated and a pop-up window is simultaneously displayed on the PC screen by the S / W (L1), and a command (L4) is sent to the HDD or SSD to check whether the number of operations works properly. The system is configured to report to the S / W that the HDD or SSD has no problem (L2), or to report the problem disk of the HDD or SSD to the S / W (L3). And S / W is programmed to generate alarm for a certain time in case popup window is erased by mistake. Also, if a problem occurs in HDD or SSD by S / W, LED lamp is turned on. In addition, through the setting of the alarm screen (FIG. 3) delivers a warning message of the real-time alarm generation.

As described above, the present invention enables the controller operator to easily check the disk status and failure status in a GUI such as a window screen, and even if the screen of the contents showing the disk failure history is inadvertently deleted without proper response, a certain time interval As it is notified again, it is possible to prevent a problem that is missed when the operator is replaced, and each disk has a different color LED lamp, it is characterized in that it is easy to identify the problem on which disk.

1 is an exemplary view of an alarm screen.
2 is an exemplary view of a screen displaying an operation state of a disc.
3 is an exemplary view of an alarm setting screen.
4 is an exemplary view showing an LED lamp indicating a disk state.
FIG. 5 is a mapping diagram illustrating a command relationship between an alarm function, a disk, and a software.

Preferred embodiments of the present invention as described above in detail with reference to the accompanying drawings as follows.

       In the case of FIG. 1, when a problem occurs on the disk, a window is displayed to the worker in a windowing environment. When a problem occurs on the disk, a pop-up window automatically appears, and the pop-up window continuously appears on the top of the screen. If it's lost, after a certain amount of time (eg after an hour), you'll be taken to the top of the new popup window. In other words, if a disk problem occurs, the warning screen should be located at the top of the GUI screen, and a new pop-up window will appear if no proper action is taken for a certain time (eg 1 hour) after the warning screen is cleared. It does not continue to create new popup windows. This creates an unnecessary number of alarms so that they do not occupy the memory area. In addition to this, depending on the type of equipment can be operated by adding a sound alarm function.

FIG. 2 is a screen displaying a state of a disk implemented by S / W since the icon is double-clicked in a window environment. It displays all the information about the disk in real time, shows the disk in question when a disk problem occurs, and displays the progress of the backup in real time as a graph when a new disk is inserted.

FIG. 3 shows that a warning screen is located at the top of the GUI screen when a disk problem occurs, and a new pop-up window appears when an appropriate action is not taken for a certain period of time (eg, 1 hour) after the warning screen is cleared. This screen displays the output cycle (user notification time interval). In this screen, user can set user notice time interval, warning screen output and warning screen output level. Warning screen output level is divided into three levels of warning, danger, and information. The user can select which level to keep the user informed in real time.

Figure 4 shows that the red LED lamp is designed to turn on when a problem occurs in the HDD or SSD.

5 is a mapping diagram showing the relationship between S / W, alarm, and HDD or SSD. S / W commands L4 as to whether or not there is no problem with the HDD or SSD, and pops up a warning screen at regular time intervals for the alarm. Warn the operator by letting (L1) come to the top of the GUI. The HDD or SSD reports a problem to the S / W when the disk has a problem (L3), or reports no problem (L2). With these commands and reports, the results of FIGS. 1, 2 and 3 and 4 can be obtained.

L1; Alarm occurrence instruction L2; Report no problem
L3; Disk report in question L4; Command to check operation of the disk

Claims (2)

In the RAID system, when a disk problem occurs, the controller operator displays the LED disk (Fig. 4) and alarm function and pop-up window (Fig. 1) by the S / W and alarm setting (Fig. 3) function.
