The present invention relates to a management mechanism for a cabinet servo system, and more particularly to a method for managing a logical disk system and a cabinet servo system using the same.

In the field of computers, computer servers have high computing power and can provide a variety of functions for multiple users to use at the same time. Therefore, the selection criteria of the computer server in the hardware device are different from those of a general personal computer (PC). The hardware device of the computer server must be able to withstand a large amount of load and have a high service life, so as to avoid data loss of the computer server due to hardware damage during the calculation work. Since the disk drive dedicated to computer servers is very expensive and has limited storage space, the disk drives of existing computer servers mostly use a hard disk array composed of a plurality of physical disks.

The basic concept of a hard disk array is to combine an array of multiple general physical drives to form an array, just like a logical disk drive. For example, the Just a Bunch Of Disks (JBOD) system is a hard disk array. The physical disk drive that makes up the JBOD system becomes a logical hard disk after being processed by the virtualization device. Therefore, the operating system only thinks that there is a hard disk with a huge capacity, and there is no need to care about how many physical drives there are.

In general, the firmware of the JBOD system does not support the provision of a system environment. The function of information (such as system temperature, voltage and other important information), therefore, the information obtained by the client is not complete. Moreover, the firmware of the JBOD system is not integrated with the server, causing the server to monitor the vulnerability in real time.

In an embodiment of the present invention, in the foregoing management method, after receiving the reply packet, the management controller may further determine whether the system temperature in the system environment information is greater than or equal to the preset temperature. When the system temperature is greater than or equal to the preset temperature, the management controller converts the fan speed adjustment command into another management interface packet, and transmits the management interface packet to the logical disk system to adjust the fan speed of the logical disk system.

In an embodiment of the present invention, in the foregoing management method, after receiving the reply packet, the management controller may further reply to the system in the packet. Environmental information for storage.

In an embodiment of the present invention, in the foregoing management method, after receiving the reply packet, the management controller may further display the system environment information in the reply packet.

The invention provides a cabinet servo system comprising a plurality of servers of a logical disk system and a management controller. Here, the logical disk system includes a plurality of storage units, and a plurality of servers are coupled to the logical disk system for accessing the logical disk system. The management controller is additionally coupled to the logical disk system to provide a user interface for the purpose of controlling the logical disk system. The management controller transfers the management interface packet to the logical disk system, so that the logical disk system performs the corresponding action according to the management interface packet, and the logical disk system transmits the return packet to the management controller after the corresponding action is performed.

In other embodiments, the cabinet servo system 100 may include two or more logical disk systems 130, which are not limited herein.

In addition, as shown in FIG. 1B, the cabinet servo system 100 further includes other servers 140_1 and servers 140_2 and the like and a switch 150. The number of servers is not limited here. The management controller 110, the logical disk system 130, the server 140_1 and the server 140_2 are all coupled to the switch 150 for communication through the switch 150. Moreover, the management controller 110 can also be directly connected to the logical disk system 130.

The logical disk system 130 can be divided into a plurality of magnetic disk areas (which may be composed of one or more hard disks and one disk area), and each of the server 140_1 and the server 140_2 has its corresponding magnetic disk area. Accessible. In the normal operation, when the cabinet servo system 100 receives the access instruction of the remote user, the management controller 110 dispatches the access instruction to one of the server 140_1 and the server 140_2 according to the content of the access instruction.

The fan 160 is disposed beside the logical disk system 130 and is controlled by the management controller 110 to determine the rotational speed of the fan 160.

The logical disk system 130 includes a plurality of storage units. Here, for example, a plurality of relatively inexpensive hard disks can be combined to form a hard disk array group, thereby implementing the logical disk system 130. For example, the logical disk system 130 can be a Just a Bunch Of Disks (JBOD) system or a Redundant Array of Independent Disks (RAID) system.

In this embodiment, since the logical disk system 130 is not exclusive to any of the server 140_1 and the server 140_2, the related information of the logical disk system 130 cannot be performed by any one of the server 140_1 and the server 140_2. The collection and processing of the logical disk system 130 can be obtained, so that the logical disk system 130 is directly monitored by the management controller 110. Here, the management controller 110 provides a user interface for the user to monitor the logical disk system 130 through the user interface.

In detail, the management interface packet is transmitted to the logical disk system 130 through the user interface provided by the management controller 110, so that the logical disk system 130 performs corresponding actions according to the management interface packet, and the logical disk system 130 is After the execution of the corresponding action is completed, the packet is sent back to the management controller 110.

The above-mentioned cabinet servo system 100 is used to explain the management method. Each step.

2 is a flow chart showing a method of managing a logical disk system in accordance with a first embodiment of the present invention.

Referring to FIG. 1 and FIG. 2, in step S205, the management interface packet is transmitted to the logical disk system 130 through the management controller 110. Here, the format of the management interface packet and the reply packet is an Intelligent Platform Management Interface (IPMI) packet. For example, the management controller 110 includes a first network port, and the logical disk system 130 includes a second network port. After the management controller 110 transmits the management interface packet to the second network of the logical disk system 130 via the first network, the logical disk system 130 converts the management interface packet into an internal control conforming to the logical disk system 130. Command to drive the internal storage unit.

After the logical disk system 130 receives the management interface packet, in step S210, the logical disk system 130 converts the management interface packet into an internal control command conforming to the logical disk system 130, thereby reading the system according to the internal control command. Environmental information. The system environment information includes at least one of a power state of the logical disk system 130, a hard disk state, an error state, sensor information, a disk array information, and field replaceable unit (FRU) information. By. The power state includes a power state and a voltage state, for example, information such as whether the power of the storage unit is turned on or off, and the value of the voltage is. The hard disk information is, for example, a usable space of the hard disk, a used space, and the like. The sensor information is, for example, the system temperature, the value read by the sensor, and the like. The disk array information is, for example, the type of the disk array. In the case of a RAID system, the RAID system includes a plurality of different grade. The FRU information is, for example, a hardware type, a manufacturer identification code, a slot number to be used, and a hardware specification.

Thereafter, after the logical disk system 130 completes the corresponding action of managing the interface packet, in step S215, the logical disk system 130 encapsulates the system environment information into the reply packet to transmit the reply packet to the management controller 110. Here, the format of the reply packet is the same as the format of the management interface packet.

Accordingly, by the above method, the state of the logical disk system 130 can be directly monitored by the management controller 110, and the logical disk system 130 can be further controlled. For example, after receiving the reply packet, the management controller 110 determines whether the system temperature in the system environment information is greater than or equal to the preset temperature. When the system temperature is greater than or equal to the preset temperature, the management controller 110 converts a fan speed adjustment command into another management interface packet and transmits it to the logical disk system 130 to adjust the fan speed of the logical disk system 130.

In addition, after receiving the reply packet, the management controller 110 can further display the system environment information in the reply packet through the user interface. Accordingly, the user can instantly know the status of the current logical disk system 130 through the user interface. In addition, after receiving the reply packet, the management controller 110 may also store the system environment information in the reply packet for later query.

Second embodiment

3 is a schematic diagram of a cabinet servo system in accordance with a second embodiment of the present invention. Referring to FIG. 3, the management controller 110 communicates with the logical disk system 130 through the connection interface 350. The connection interface 350 is, for example, an Inter-Integrated Circuit (I ² C) bus or a Local Area Network (LAN).

In the present embodiment, the logical disk system 130 includes a built-in operating system 310, a driver 320, and a storage unit 330. For convenience of explanation, only one storage unit 330 is illustrated here. In other embodiments, the logical disk system 130 may also include two or more storage units 330. Here, it is assumed that the storage unit 330 is configured with a fan 340. In other embodiments, including multiple storage units 330, one storage unit 330 is not limited to one fan 340. Alternatively, multiple storage units 330 may use one fan 340 in common, or one storage unit 330 may be configured with multiple fans 340. . Here, the IPMI packet is described as a management interface packet.

The IPMI packet is transmitted from the management controller 110, that is, transmitted through the first network of the management controller 110, and transmitted to the second network port of the logical disk system 130, as shown in step S31.

Then, after receiving the IPMI packet, the logical disk system 130 generates a corresponding processing mechanism through the embedded operating system 310, that is, parses the data content of the IPMI packet, thereby disassembling the received IPMI packet layer to Header, data content, verification code, and more. After that, after the embedded operating system 310 understands the information contained in the IPMI packet, the corresponding command in the IPMI packet is converted into an internal control command of the logical disk system 130, and the internal control command is transmitted to the driver of the storage unit 330. 320, as shown in step S32. According to this, the logical disk system 130, the storage unit 330 can be driven by the driver 320 by the existing command mode, as shown in step S33. Then, the driver 320 can obtain the system environment information from the storage unit 330, as shown in step S34.

Thereafter, the driver 320 transmits the obtained system environment information to the embedded operating system 310 as shown in step S35. The embedded operating system 310 encapsulates the obtained reply data, that is, system environment information, into a reply packet (another IPMI packet). Then, the embedded operating system 310 transmits the reply packet to the management controller 110 through the network, as shown in step S36.

Thereafter, the management controller 110 allows the user to know the status of the logical disk system 130 through a user interface such as a web interface. Accordingly, the reaction mechanism can be automated by the management controller 110 for system environment information. For example, when the system temperature of the logical disk system 130 is too high, the management controller 110 can automatically increase the rotational speed of the fan 340 to cool the logical disk system 130. That is, after the management controller 110 encapsulates the fan rotational speed adjustment command into an IPMI packet, the fan 340 of the storage unit 330 is controlled via the above steps S31 to S33.

In addition, the management controller 110 can also directly connect to the fan 340 by using another connection interface, thereby directly controlling the rotation speed of the fan 340. Let me give another example.

Third embodiment

Referring to FIG. 4, the embodiment is substantially the same as the second embodiment, except that in the embodiment, the management controller 110 can be directly coupled to the fan 340 by using the connection interface 360, that is, when the logical disk system is used. When the system temperature of 130 is too high, the management controller 110 directly transmits the fan speed adjustment command to the fan 340 through the connection interface 360 to automatically increase the rotational speed of the fan 340 to cool the logical disk system 130.

In summary, in the above embodiment, in the server, an additional management controller is connected to the logical disk system, and the management interface packet is transmitted from the management controller to the logical disk system; and the logical disk system receives the After the management interface packet, the related response is made to the content of the management interface packet, and the response reply packet is sent to the management controller. According to this, it is not necessary to turn on all the servers to obtain the information in the logical disk system. According to this, the logical disk system can be monitored in real time and an immediate processing mechanism can be made. And, the system environment information about the logical disk system is recorded in the management controller so that the user can view it later. In addition, the management controller and the logical disk system can also use IPMI format packets to communicate, which not only has security and verification mechanisms, but also enhances the future consistency and scalability of the modules.
