Description

Technical Field

[0001] The present application relates to the field of storage technology, and in particular to a method, device, and medium for adjusting a shared area. Background Art

[0002] In the era of big data, server usage and maintenance are crucial. Server maintenance requires both in-band and out-of-band operations, such as configuring and stress testing Redundant Arrays of Independent Disks (RAID). Therefore, in-band and out-of-band information exchange has become a critical issue, and this exchange requires a shared area. A shared area is a storage area accessible both in-band and out-of-band on a server. It's typically an idle storage area on the baseboard management controller (BMC), accessible via Intelligent Platform Management Interface (IPMI) commands. Limited by the BMC's storage size, the shared area is relatively small; for example, some BMCs have a shared area size of only 512 bytes. Currently, methods for in-band and out-of-band data exchange using a shared area pre-define the shared area's location, i.e., the starting position and size of the shared area are fixed. For example, a shared area is pre-determined within the BMC or storage area, and specific data exchange rules are then set to facilitate data exchange within the shared area.

[0003] However, due to the limitation of BMC storage area size, the shared area cannot be set too large, otherwise other storage areas will be too small. However, if the shared area is too small, the various functions of the server in the shared area will not be able to operate normally.

[0004] Therefore, it can be seen that how to ensure that the shared area can meet the normal use of the server and does not occupy too many storage resources for a long time is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0019] The adjusting the size of the shared area of ​​the server according to the determined storage space size required for in-band and out-of-band data interaction of the server includes:

[0020] On the basis of ensuring that the size of the shared area is within the range of the maximum area, the size of the shared area of ​​the server is adjusted according to the determined storage space size required for in-band and out-of-band data interaction of the server.

[0021] Preferably, if the maximum area range of the shared area cannot simultaneously meet the requirements of various functions currently executed by the server, controlling the server to execute various functions includes:

[0022] The server is controlled to perform data interaction in the shared area in batches when executing various functions.

[0023] Preferably, if the function currently executed by the server includes upgrading the board, there are multiple boards to be upgraded, and the maximum area range of the shared area cannot simultaneously meet the requirements of each function currently executed by the server, upgrading the board includes:

[0037] The shared area adjustment method provided in the present application provides a dynamic adjustment scheme for the adjustment of the shared area. The shared area is a storage area that can be accessed by the server both in-band and out-band. The information exchange between the server in-band and out-band needs to be completed through the shared area. When the server executes a function, it needs to exchange data in the shared area. When the server is currently executing different functions, the size of the shared area required for data exchange is different. In addition, if the server information is different, the size of the shared area required for data exchange when the server executes the same function is also different. Therefore, this scheme first obtains the function and server information currently executed by the server; then, based on the function currently executed by the server and the corresponding server information, the size of the storage space required for the server to exchange data in-band and out-band is determined; finally, the size of the server's shared area is dynamically adjusted based on the determined storage space required for the server to exchange data in-band and out-band. Compared with the current scheme of fixing the shared area in advance, this scheme can ensure that the shared area can adjust the size of the shared area in real time, which can meet the normal use of the server without occupying too many storage resources for a long time.

[0043] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0044] The core of this application is to provide a method, device and medium for adjusting a shared area to ensure that the shared area can meet the normal use of the server and does not occupy too many storage resources for a long time.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] In the big data era, server usage and maintenance are crucial. Server maintenance requires the combined use of in-band and out-of-band methods, such as RAID configuration and stress testing. RAID combines multiple independent disks into a massive disk array, leveraging the synergistic effect of individual disks providing data to improve overall disk system performance. This technology divides data into multiple segments and stores them on separate hard drives. In some cases, servers require RAID configuration. Server stress testing involves testing the central processing unit (CPU) and memory. The resulting stress test results include total machine power, CPU power, CPU temperature, CPU user utilization, CPU system utilization, CPU idle utilization, memory utilization, memory power, air inlet temperature, and air outlet temperature. These operations require in-band and out-of-band data exchange, making this information exchange crucial. This information exchange requires a shared area. A shared area is a storage area accessible both in-band and out-of-band on a server. It's typically an idle storage area within the BMC. The BMC can perform firmware upgrades, check device configuration, and other operations on a machine even when the machine is not powered on. The shared area can be accessed via IPMI commands. Limited by the BMC's storage size, the shared area is relatively small. For example, some BMCs have a shared area size of only 512 bytes. Currently, methods for in-band and out-of-band data exchange using a shared area pre-set the location of the shared area, i.e., the starting position and size of the shared area are fixed. For example, a shared area is pre-determined within the BMC or storage area, and then certain data exchange rules are set to facilitate data exchange within the shared area. However, due to the BMC storage area size limitation, the shared area cannot be set too large, otherwise other storage areas will be too small. However, a too small shared area will prevent the various server functions within the shared area from functioning properly. Therefore, embodiments of the present application provide a method to ensure that the shared area can meet the normal needs of the server and does not occupy excessive storage resources for an extended period of time. When performing in-band and out-of-band data interaction between servers using the method provided by this application, the size, starting position, data interaction rules, etc. of the shared area can be dynamically determined based on the server's own attributes and the functions of the in-band operation, thereby realizing in-band and out-of-band data interaction between different servers under different functional configurations. This solution can dynamically set the interaction range and rules of the shared area for different functions of different servers, and each time the function is expanded, there is no need to manually change the code to interact with in-band and out-of-band data. When maintaining servers in batches, machines with different configurations and different functional requirements can all be stably compatible. Figure 1 A flowchart of a method for adjusting a shared area provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes the following steps:

[0047] S10: Obtain the function currently executed by the server and server information.

[0048] S11: Determine the storage space required for in-band and out-of-band data interaction of the server based on the function currently executed by the server and corresponding server information.

[0049] S12: Adjust the size of the shared area of ​​the server according to the determined storage space size required for in-band and out-of-band data interaction of the server.

[0050] Generally, before obtaining the functions currently executed by the server, it is necessary to first obtain the functions that the server can support, and after obtaining the server information, set rules based on the functions that the server can support and the server information. The functions currently executed by the server are within the range of functions supported by the server. After obtaining the functions currently executed by the server, the size of the storage space required for in-band and out-of-band data interaction of the server can be determined according to the set rules. Among them, the functions that the server can support generally include RAID configuration, stress testing, hard disk erasure, and board upgrades; server information may include server model, BMC model, BMC storage area size, number of CPUs, number of memories, RAID card model, number of RAID cards, number of physical disks, board type, and number of boards, etc. The embodiment of the present application provides an example of a specific rule. It should be noted that this example is just one of the solutions given for the convenience of explanation, and is not limited to the solution of this example in actual application. The specific rules are as follows:

[0051] When configuring RAID on a server, you can first define the status of creating a logical disk, such as success, failure, or RAID card not found. Then, you can use four bits (16 combinations) to represent the status of a logical disk, that is, one byte represents the status of two logical disks. Based on this rule, when configuring RAID on a server, you can determine the amount of storage space required for in-band and out-of-band data interaction on the server based on the RAID card model, number of RAID cards, number of physical disks, etc.

[0052] The function performed by the server may also be a stress test. First of all, stress testing is divided into CPU stress testing and memory stress testing. The result data that needs to be returned for the stress test include: total machine power, CPU power, CPU temperature, CPU user utilization, CPU system utilization, CPU idle utilization, memory utilization, memory power, air inlet temperature, air outlet temperature, etc. An integer or two decimal places for each data point is sufficient to represent the machine status. According to this rule, the size of the storage space required for stress testing can be determined. When the server is performing a stress test, it needs to return the above data, and the number of CPUs and memory in the server will affect the amount of the above data. Therefore, at this time, the amount of storage space required for in-band and out-of-band data interaction of the server can be determined based on the number of CPUs and memory.

[0053] Service cards include network cards, RAID cards, Fibre Channel (HBA) cards, and hard drives. Similar to RAID configurations, card upgrades require storage of upgrade results. Four digits represent the upgrade result for each card. The required shared area size can be adjusted based on the actual card types and number on the server.

[0054] The server also supports hard drive erasure. The data exchanged for this function is the erasure progress, which ranges from 0 to 100. Selecting a single byte will suffice. Therefore, if the server currently performs hard drive erasure, resizing the shared area will reserve a single byte to ensure proper hard drive erasure.

[0055] After determining the size of the storage space required for in-band and out-of-band data interaction on the server, the size of the shared area of ​​the server can be adjusted according to the determined storage space size. The solution provided in the embodiment of the present application dynamically obtains the size of the shared area according to certain rules, and the dynamic adjustment of the size of the shared area can be achieved without manually changing the code. In addition to adjusting the size of the shared area, the solution provided in the embodiment of the present application also adjusts the position of the shared area according to the functions currently executed by the server and the server information. Specifically, the starting position of the shared area can be determined according to the server model, BMC model, and BMC storage area size. Generally, after obtaining the starting position and size of the shared area, the overall position of the shared area is obtained. After determining the shared areas of different servers based on the server information and the functions currently executed by the server, in-band and out-of-band data interaction can also be performed on multiple servers in batches.

[0056] Additionally, the maximum size of the shared area can be determined based on the server model, BMC model, and BMC storage area size. If the determined maximum size meets the functional requirements, the size of the shared area can be adjusted to facilitate data exchange based on the order in which the functions are executed. If the maximum size of the shared area does not meet the current functional requirements of the server (i.e., the maximum size of the shared area is smaller than the required space), each function can be executed in batches. For example, during a board upgrade, if the shared area cannot support all boards simultaneously, the function can be broken down into individual board upgrade data exchanges. Each time a board is upgraded, data exchange for the previous board is completed before the next board is upgraded. When executing functions in batches, the following three bytes are required to assist in recording content: Select a byte (byte a) to record the function status: not started, in progress, or completed; select a byte (byte b) to record the current data exchange status: read or unread; and select a byte (byte c) to record the function being processed (function codes can be agreed upon in advance). If byte a has not yet begun or has already ended, there's no need to read any further bytes. If byte b has already been read, there's no need to read any further bytes either, reducing the frequency and pressure of data reads in the shared area. If byte a is in progress and byte b is unread, read the remaining data. Once the data is read, byte b is marked as read. After the in-band operation sees that byte b has been read, it can continue writing new data. This allows for in-band and out-of-band data exchange.

[0057] The shared area adjustment method provided in the embodiment of the present application provides a dynamic adjustment scheme for the adjustment of the shared area. The shared area is a storage area that can be accessed by the server both in-band and out-band. The information exchange between the server in-band and out-band needs to be completed through the shared area. When the server executes a function, it needs to exchange data in the shared area. When the server is currently executing different functions, the size of the shared area required for data exchange is different. In addition, if the server information is different, the size of the shared area required for the server to execute the same function for data exchange is also different. Therefore, this scheme first obtains the function and server information currently executed by the server; then, based on the function currently executed by the server and the corresponding server information, the size of the storage space required for the server to exchange data in-band and out-band is determined; finally, the size of the shared area of ​​the server is dynamically adjusted based on the determined size of the storage space required for the server to exchange data in-band and out-band. Compared with the method of fixing the shared area in advance in the current scheme, this scheme can ensure that the size of the shared area can be adjusted in real time, which can meet the normal use of the server without occupying too many storage resources for a long time.

[0058] The above embodiment does not limit the content of the server information. This embodiment provides a specific solution, in which the server information includes at least one of the following: server model, BMC model, BMC storage area size, number of CPUs, number of memory, RAID card model, number of RAID cards, number of physical disks, board type, and number of boards. In practice, the server requires different server information when performing different functions. The specific corresponding relationship is as follows: Based on the current function of the server and the corresponding server information, the storage space required for in-band and out-of-band data exchange is determined, including:

[0059] If the server's current function includes RAID configuration, the amount of storage space required for in-band and out-of-band data exchange on the server is determined based on the RAID card model, number of RAID cards, and number of physical disks. When configuring RAID, the server can first define the status of creating logical disks, such as success, failure, or RAID card not found. The status of a logical disk can then be represented by four bits (16 possible combinations), meaning one byte represents the status of two logical disks. Based on this rule, the size of the shared area required for different RAID card models, number of RAID cards, and number of physical disks can be calculated.

[0060] If the server's current function includes stress testing, the required storage space is determined based on the number of CPUs and memory. Stress testing is divided into CPU stress testing and memory stress testing. The required stress test result data includes: total machine power, CPU power, CPU temperature, CPU user utilization, CPU system utilization, CPU idle utilization, memory utilization, memory power, air inlet temperature, and air outlet temperature. Each data point should be an integer or two decimal places sufficient to represent the machine status. This rule can be used to determine the storage space required for different numbers of CPUs and memory.

[0061] If the server's current functions include card upgrades, the amount of storage space required for in-band and out-of-band data exchange can be determined based on the card type and number. Card upgrades are categorized as network card upgrades, RAID card upgrades, HBA card upgrades, and hard drive upgrades. Similar to RAID configurations, card upgrades require storage of the upgrade results, with four bits representing the upgrade result for each card. Therefore, based on this rule, once the actual card type and number on the server are known, the required shared area size can be determined.

[0062] If the server's current function includes hard drive erasure, reserve one byte when determining the storage space required for in-band and out-of-band data exchange to ensure proper hard drive erasure. The data exchanged for the hard drive erasure function is the erasure progress, which ranges from 0 to 100. Selecting a single byte will satisfy the requirement. Therefore, if the server's current function includes hard drive erasure, reserve one additional byte to ensure proper hard drive erasure.

[0063] It can be seen that the solution provided in this embodiment provides the server data required for the server to adjust the size of the shared area when executing different functions. According to the above correspondence, the size of the shared area can be accurately obtained. However, it should be noted that the solution provided in the above embodiment is only an example of the embodiment of the present application and does not limit other solutions. In a specific implementation, the server may only execute a single function at the same time, or it may execute multiple functions at the same time. If the server only executes a single function at a time, then according to the correspondence between the above function and the server information, the size of the storage space required for the server to interact with data in-band and out-of-band can be determined according to the corresponding server information. If the server executes multiple functions at the same time, then when adjusting the size of the shared area, it is necessary to take into account the storage resources that multiple functions need to occupy.

[0064] In specific implementation, when adjusting the size of the shared area, it is necessary to ensure that the size of the shared area is within the maximum area range to ensure that all functions can be carried out normally. Therefore, before adjusting the size of the shared area of ​​the server according to the storage space size required for in-band and out-band data interaction of the server, it also includes: determining the maximum area range of the shared area according to the server model, BMC model, and BMC storage area size. Adjusting the size of the shared area of ​​the server according to the storage space size required for in-band and out-band data interaction of the server includes: on the basis of ensuring that the size of the shared area is within the maximum area range, adjusting the size of the shared area of ​​the server according to the storage space size required for in-band and out-band data interaction of the server. In addition, the starting position of the shared area can also be determined according to the server model, BMC model, and BMC storage area size.

[0065] In actual applications, a server may simultaneously execute multiple functions, resulting in insufficient storage resources in the shared area. Alternatively, it may consume excessive storage resources when executing a single function. For example, service cards include network cards, RAID cards, HBA cards, and hard drives. A network card is computer hardware that enables computer communication on a computer network. An HBA, also known as a host bus adapter, is essential for connecting a host to a network. A server needs to upgrade these cards, but the number of cards varies. If multiple cards are upgraded simultaneously, the storage resources in the shared area may not be sufficient to support all of them. Therefore, if the maximum area of ​​the shared area cannot simultaneously meet the needs of all the functions currently executed by the server, controlling the server to execute each function may include controlling the server to exchange data in batches within the shared area when executing each function. For example, if the server is currently executing a card upgrade and there are multiple cards to be upgraded, and the maximum area of ​​the shared area cannot simultaneously meet the needs of all the functions currently executed by the server, upgrading the cards may include upgrading each card in batches. Correspondingly, controlling the server to perform data interaction in the shared area in batches when executing each function includes: recording the status of each function and the current data interaction status; and controlling the server to perform data interaction in the shared area in batches when executing each function based on the status of each function and the current data interaction status. Specifically, the function status can be recorded using byte a, with the specific status being: not started, in progress, or completed. The current data interaction status can be recorded using byte b, with the specific status being: read or unread. Function codes can also be agreed upon in advance, and the codes can be recorded using byte c to record the function being processed. When byte a is not started or completed, there is no need to read other bytes; when byte b is in the read state, there is no need to read other bytes either, thereby reducing the number and pressure of data reads in the shared area. When byte a is in progress and byte b is in the unread state, other data is read, and after reading the data, byte b is set to the read state. After the in-band operation reads the read state of byte b, new data continues to be written, thereby achieving the effect of in-band and out-band data interaction. The solution of using three bytes to record status in this example is only one of the embodiments of this application and does not limit other solutions of this application. The solution provided in the embodiment of the present application solves the problem of insufficient storage resources in the shared area by executing various functions in batches.

[0066] In the above embodiments, the method for adjusting the shared area is described in detail. This application also provides corresponding embodiments of the device for adjusting the shared area. It should be noted that this application describes the embodiments of the device from two perspectives: one is based on the functional module perspective, and the other is based on the hardware perspective.
