[0002] In the storage field, whether it is a main control cabinet or an expansion cabinet, if you want to carry business on the storage, the hard drives contained in the cabinet must be managed before storing data. This allows the storage cluster to manage the hard drives in the expansion cabinet, thereby establishing the storage pool, storage volume, and RAID type required by the user to undertake storage business.

[0003] However, existing Ethernet-based expansion cabinets (EBOF, Ethernet attached just a Bunch OfFlash) have the problem of multiple storage clusters managing the same expansion cabinet, which causes confusion when writing data to the hard drives in the expansion cabinet and possible data loss.

[0062] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] It should be understood that in the description of this application, unless the context clearly requires otherwise, words such as "include", "comprises", and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, as "including but not limited to".

[0064] It should also be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0065] It should be noted that the terms "S1", "S2", etc. are used only for the purpose of describing the steps and do not specifically refer to the order or sequence, nor are they used to limit this application. They are merely for the convenience of describing the method of this application and should not be understood as indicating the order of the steps. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0066] As described in the background technology, when deploying services on a storage system, it is necessary to manage expansion cabinets and hard disks. In existing solutions, the storage cluster directly executes hard disk drive change instructions to achieve management and control of the specified hard disk. However, precisely because the hard disk drive change instructions are directly executed on the specified hard disk, the existing solution manages the expansion cabinet where the specified hard disk is located while the storage cluster manages the hard disk without any verification, resulting in one expansion cabinet being managed by multiple storage clusters at the same time, causing hard disk data in the expansion cabinet to be lost. Therefore, the present application provides a management method for Ethernet-based expansion cabinets, which enables the storage cluster to manage the expansion cabinet while ensuring the security of the hard disk data in the expansion cabinet.

[0067] Example 1

[0068] The embodiment of the present application provides an Ethernet-based expansion cabinet management method, which is applied to a storage system. The storage system is a system that provides storage services for users. In this embodiment, the storage business is taken over by at least one storage cluster and an Ethernet-connected Block-scale Open Flash (EBOF). It can be understood that other types of expansion cabinets can also be included in the storage system. Among them, the Ethernet-based expansion cabinet is a new type of storage architecture that uses the Ethernet structure to expand the flash memory and separates the storage from the calculation in the best way, so that the storage resources can be more flexibly allocated to different computing nodes, improving resource utilization, thereby improving more efficient storage performance. At the same time, due to its low cost, the scope of application is gradually expanding, and it is widely used in edge computing, enterprise-level data centers and cloud data centers. This embodiment manages the Ethernet-based expansion cabinet. For the sake of convenience, the following text only refers to the expansion cabinet, that is, all the expansion cabinets in this application are Ethernet-based expansion cabinets.

[0069] Specifically, such as Figure 1 As shown, the method disclosed in the embodiment of the present application is used to implement the management of the expansion cabinet of the storage cluster, including the following contents:

[0070] S1. In response to detecting the existence of a storage cluster, executing a hard disk drive change instruction on any hard disk in a target expansion cabinet based on Ethernet, determining whether the storage cluster meets the cabinet management condition of the target expansion cabinet.

[0071] Specifically, the hard disk drive change instruction is a chdrive command, and may also be other commands developed in the future for changing the hard disk drive status, which is not restricted by this application.

[0072] In some specific implementation scenarios, before the storage cluster executes the hard disk drive change instruction on any hard disk in the Ethernet-based target expansion cabinet, the storage cluster further includes:

[0073] Detect and determine the managed status of the target expansion cabinet. The managed status indicates the storage cluster from which the expansion cabinet accepts management commands. Managed status includes initial status, normal status, and abnormal status. The initial status indicates that the expansion cabinet is not controlled by any storage cluster; the normal status indicates that the expansion cabinet is normally controlled by the storage cluster, and is controlled by only one storage cluster; the abnormal status indicates that the expansion cabinet is abnormal and is being managed by multiple storage clusters simultaneously. Specifically, you can use command line tools or establish a third-party management tool to detect the storage cluster from which the expansion cabinet accepts management commands.

[0074] If the managed state of the target expansion cabinet is abnormal, an abnormal alarm is generated and the execution of the hard disk drive change instruction on the target hard disk in the target expansion cabinet is stopped; wherein, the abnormal alarm can be fed back to the user through a visual prompt to prompt the user to check the target expansion cabinet and repair any abnormal problems that may exist therein, or it can be prompted to the user in other forms, which is not restricted by this application. If the managed state of the target expansion cabinet is normal or initial, the storage cluster is allowed to execute the hard disk drive change instruction on the target hard disk. This application sets a pre-state detection link before executing the hard disk drive change instruction on the target hard disk in the storage cluster, detects the managed state of the target expansion cabinet, stops the management and control of the expansion cabinet in an abnormal state, maximizes the success rate of the hard disk drive change instruction execution, and promptly repairs the abnormal expansion cabinet to avoid possible data loss problems in the expansion cabinet.

[0075] In some specific implementation scenarios, in response to detecting that the managed state of a target expansion cabinet is abnormal, an initialization operation is performed on the target expansion cabinet to ensure that the target expansion cabinet is in an initial state. The initialization operation includes changing the target cluster identifier written in the backplane key product data within the target expansion cabinet to 0, that is, clearing the field in the backplane key product data that contains the target cluster identifier. When the managed state of the target expansion cabinet is detected to be abnormal, the field in the target expansion cabinet that already contains the target cluster identifier is written back to empty, clearing the impact of the permissions of the storage cluster that has previously obtained management permissions on the expansion cabinet, thereby facilitating the subsequent reconfiguration of the manageable storage cluster.

[0076] In some specific implementation scenarios, in response to detecting that a storage cluster executes a hard disk drive change instruction on any hard disk in an Ethernet-based target expansion cabinet, determining whether the storage cluster meets the cabinet management conditions of the target expansion cabinet includes:

[0077] Obtain the storage cluster identifier corresponding to the storage cluster; obtain the target cluster identifier written in the target expansion cabinet; if the target cluster identifier written in the target expansion cabinet is 0, determine that the storage cluster meets the cabinet management conditions; compare the storage cluster identifier with the target cluster identifier to determine whether the storage cluster identifier and the target cluster identifier match; if the storage cluster identifier and the target cluster identifier match, determine that the storage cluster meets the cabinet management conditions; if the storage cluster identifier and the target cluster identifier do not match, determine that the storage cluster does not meet the cabinet management conditions. If the storage cluster identifier and the target cluster identifier are consistent, determine that the storage cluster corresponding to the storage cluster identifier meets the conditions for managing the expansion cabinet. If the target cluster identifier written in the expansion cabinet is 0, it indicates that the expansion cabinet is not configured with a manageable storage cluster. In this case, it can also be determined that the management cluster meets the conditions for managing the expansion cabinet. Before granting the storage cluster management authority over the expansion cabinet, verify whether the storage cluster meets the cabinet management conditions for the expansion cabinet to avoid a situation where a single expansion cabinet is managed by multiple storage clusters.

[0078] Specifically, the above-mentioned method for obtaining the target cluster identifier written in the target expansion cabinet specifically includes: in response to detecting the existence of a storage cluster executing a hard drive change instruction on the target hard drive, triggering the platform management module in the storage system to read the target cluster identifier written in the target cluster identifier field in the backplane vital product data (VPD) in the target expansion cabinet. Among them, the backplane vital product data is an indispensable part of the expansion cabinet, and the writing of key product information is achieved through a specific circuit design. In this application, the target cluster identifier can be pre-written into the expansion cabinet to facilitate subsequent viewing and other operations.

[0079] Specifically, the method for obtaining the storage cluster identifier corresponding to the storage cluster specifically includes, in response to detecting that a storage cluster executes a hard drive change instruction on a target hard drive, triggering a cabinet management module in the storage system to parse a specified page based on the expansion cabinet management protocol to obtain the storage cluster identifier. The expansion cabinet management protocol is preferably set to the SES (SCSI Enclosure Services) protocol, but may also be other protocols that can achieve management of expansion cabinets, which is not restricted by this application. In the SES protocol, page pages are used to store and report status information of the expansion cabinet and its internal devices. The cabinet management module obtains the storage cluster identifier of the storage cluster that initiates the hard drive change instruction to the hard drive in the expansion cabinet (i.e., manages the hard drive) by parsing the specified page according to the SES protocol. The cabinet management module compares the storage cluster identifier with the target cluster identifier to determine whether the storage cluster identifier matches the target cluster identifier. The present application achieves a rapid determination of whether the storage cluster meets the cabinet management conditions by searching the backplane key product data of the expansion cabinet and quickly obtaining the target cluster identifier already written in the expansion cabinet and the storage cluster identifier corresponding to the storage cluster that executes the hard drive change instruction through the expansion cabinet management protocol.

[0080] S2. In response to detecting that the storage cluster meets the cabinet management condition, granting the storage cluster management authority over the target expansion cabinet.

[0081] In some specific implementation scenarios, the method disclosed in this embodiment also includes a method for writing a target cluster identifier in a target expansion cabinet: pre-configuring and saving the management relationship between the storage cluster and the expansion cabinet in the storage system, wherein the storage cluster corresponding to the expansion cabinet is unique, that is, by setting the relationship between the expansion cabinet and the storage cluster in advance, specifying the manageable storage cluster corresponding to each expansion cabinet, thereby improving the stability of the storage system; according to the management relationship, searching for the storage cluster identifier of the target storage cluster corresponding to the target expansion cabinet; confirming that the storage cluster identifier of the target storage cluster is the target cluster identifier corresponding to the target expansion cabinet and writing the target cluster identifier into the backplane key product data of the target expansion cabinet.

[0082] In some specific implementation scenarios, in response to detecting that the target cluster identifier in the backplane key product data of the target expansion cabinet is 0, the target expansion cabinet may not have yet written the storage identifier corresponding to the storage cluster with which it has a management relationship, or the target expansion cabinet may have performed an initialization operation after detecting an abnormal state, resulting in the storage cluster identifier of the corresponding manageable storage cluster not being written into the expansion cabinet. A detection is performed to determine whether a storage cluster has initiated a hard drive change instruction for a target hard drive in the target expansion cabinet; if one storage cluster has initiated a hard drive change instruction for the hard drive in the target expansion cabinet, a first operation is performed; if multiple storage clusters have initiated hard drive change instructions for the hard drive in the target expansion cabinet, a second operation is performed.

[0083] Among them, the first operation includes: starting the inspection and recovery task to use the storage cluster identifier corresponding to the storage cluster as the target cluster identifier and write it into the backplane key data of the target expansion cabinet; at this time, since the target expansion cabinet has not received the management of any storage cluster, and the target hard disk contained in the cabinet is managed by this storage cluster while receiving the hard disk drive change instruction, it can be directly determined that the configured storage cluster has management authority over the target expansion cabinet, and there is no need to consider whether the target expansion cabinet has been pre-configured with a management relationship with the management cluster.

[0084] The second operation includes:

[0085] In response to a storage cluster that has a management relationship with the target expansion cabinet being included in the storage cluster, a review and recovery task is initiated to use the storage cluster identifier of the storage cluster that has a management relationship with the target expansion cabinet as the target cluster identifier and write it into the backplane key data of the target expansion cabinet. In response to the storage cluster not including the storage cluster that has a management relationship with the target expansion cabinet, a change time node at which multiple storage clusters initiate the hard drive change instruction is obtained, and a review and recovery task is initiated to write the target cluster identifier into the backplane key data of the target expansion cabinet. The target cluster identifier is the storage cluster identifier corresponding to the storage cluster with the earliest change time node among the obtained storage clusters. If multiple storage clusters exist for the target expansion cabinet, a cluster with management authority is selected from the multiple storage clusters, giving priority to the storage cluster with a management relationship with the target expansion cabinet. If no storage cluster exists, the storage cluster that executed the hard drive change instruction earliest is determined to be the only cluster with management authority.

[0086] In addition, in order to improve the business capabilities and data security of the storage system, the present application also proposes a disaster recovery method, which specifically includes: regularly detecting the operating status of the storage cluster that matches the expansion cabinet; in response to detecting an abnormality in the storage cluster, clearing the cluster identifier corresponding to the storage cluster written in the backplane key data in the expansion cabinet and querying whether the storage cluster with the abnormality has a corresponding mirror cluster; if the storage cluster with the abnormality has a corresponding mirror cluster, directly granting the mirror cluster the authority to manage the expansion cabinet, and writing the cluster identifier corresponding to the mirror cluster into the backplane key data of the expansion cabinet. When the abnormality in the storage cluster is detected, the storage system generates a warning to prompt the user that the storage cluster has failed and prompts the user to isolate and repair the storage cluster. If the storage cluster with the abnormality does not have a mirror cluster, the above-mentioned second operation is performed to select a new cluster to manage the expansion cabinet. The present application provides a method for responding to abnormalities in the storage cluster of the expansion cabinet under management. If a mirror cluster exists, the mirror cluster is directly called up for replacement, or a new storage cluster is selected for management. While increasing the disaster recovery capability of the storage system, the normal operation of the storage business in the expansion cabinet is greatly guaranteed, thereby improving the business capability of the entire storage system and ensuring the security of the data in the storage system.

[0087] Before granting the storage cluster management authority over a specified expansion cabinet, this application adds a check on whether the storage cluster has the cabinet management conditions, thereby avoiding the situation where multiple clusters may manage the same expansion cabinet at the same time, causing the risk of data loss, and greatly improving the security of the hard disk data in the expansion cabinet.

[0088] Example 2

[0089] Corresponding to the above embodiment 1, as Figure 2 As shown, an embodiment of the present application further provides a management system for an Ethernet-based expansion cabinet, including:

[0090] A processing module 210 is configured to, in response to detecting the presence of a storage cluster, execute a hard disk drive change instruction on any hard disk in a target Ethernet-based expansion cabinet, and determine whether the storage cluster satisfies a cabinet management condition of the target expansion cabinet;

[0091] The management module 220 is configured to grant the storage cluster management authority over the target expansion cabinet in response to detecting that the storage cluster meets the cabinet management condition.

[0094] In some implementation scenarios, the processing module 210 is also used to, in response to detecting the existence of a storage cluster executing a hard disk drive change instruction on the target hard disk, trigger the platform management module in the storage system to read the target cluster identifier written in the target cluster identifier field in the backplane key product data in the target expansion cabinet; in response to detecting the existence of a storage cluster executing a hard disk drive change instruction on the target hard disk, trigger the cabinet management module in the storage system to parse the specified page based on the expansion cabinet management protocol to obtain the storage cluster identifier; and compare the storage cluster identifier with the target cluster identifier through the cabinet management module to determine whether the storage cluster identifier matches the target cluster identifier.

[0095] In some implementation scenarios, the processing module 210 is also used to pre-configure and save the management relationship between the storage cluster and the expansion cabinet in the storage system, wherein the storage cluster corresponding to the expansion cabinet is unique; based on the management relationship, the storage cluster identifier of the target storage cluster corresponding to the target expansion cabinet is searched; the storage cluster identifier of the target storage cluster is confirmed to be the target cluster identifier corresponding to the target expansion cabinet and the target cluster identifier is written into the backplane key product data of the target expansion cabinet.

[0096] In some implementation scenarios, the processing module 210 is also used to perform an initialization operation on the target expansion cabinet to ensure that the target expansion cabinet is in an initial state in response to detecting that the managed state of the target expansion cabinet is an abnormal state; wherein, the initialization operation includes: changing the target cluster identifier written in the backplane key product data in the target expansion cabinet to 0.

[0097] In some implementation scenarios, the processing module 210 is further configured to, in response to detecting that a target cluster identifier in the backplane key product data of the target expansion cabinet is 0, detect whether a storage cluster initiates a hard disk drive change instruction for a target hard disk in the target expansion cabinet; if one storage cluster initiates a hard disk drive change instruction for the hard disk in the target expansion cabinet, perform a first operation; if multiple storage clusters initiate hard disk drive change instructions for the hard disk in the target expansion cabinet, perform a second operation;

[0098] The first operation includes: starting a review and recovery task to use the storage cluster identifier corresponding to the storage cluster as a target cluster identifier and writing the identifier into the backplane key data of the target expansion cabinet;

[0099] Among them, the second operation includes: in response to the storage cluster containing a storage cluster that has a management relationship with the target expansion cabinet, starting the review and recovery task to use the storage cluster identifier of the storage cluster that has a management relationship with the target expansion cabinet as the target cluster identifier and write it into the backplane key data of the target expansion cabinet; in response to the storage cluster not containing a storage cluster that has a management relationship with the target expansion cabinet, obtaining the change time nodes at which multiple storage clusters initiate the hard disk drive change instructions, and starting the review and recovery task to use the target cluster identifier and write it into the backplane key data of the target expansion cabinet, the target cluster identifier being the storage cluster identifier corresponding to the storage cluster with the earliest change time node in the obtained storage clusters.
