Description

Technical Field

Therefore, in order to increase the storage capacity of the memory array, the memory array needs to be expanded. At present, the capacity expansion of the storage array is mainly carried out by adopting the following modes: 1. inserting a newly added hard disk into a hard disk slot position of an existing hard disk frame of a storage array so as to increase the capacity of the storage array; 2. under the condition that the storage array does not have an idle hard disk slot position or the idle hard disk slot position cannot meet the existing service requirement, the capacity of the storage array is increased by increasing a hard disk frame in the array; 3. when the number of controllers needs to be increased to improve the overall performance of the storage array, capacity expansion can be performed by increasing the number of controllers, wherein the controllers can carry a plurality of hard disk frames.

Fig. 2 is a schematic flow chart of another capacity expansion method according to an embodiment of the present invention. As shown in fig. 2, the capacity expansion method according to this embodiment includes the steps of:
s200, when receiving the expansion starting instruction, generating expansion configuration parameters required by expansion.
In the embodiment of the invention, when an operation user needs to expand the cluster of the controller, the operation user can input an expansion starting instruction through the terminal equipment for managing the cluster. The terminal equipment can be internally provided with management software, and an operation user can input a capacity expansion starting instruction through an input device of the terminal equipment. The input device may include a touch screen, keys, and the like.
In the embodiment of the invention, when the main controller receives the capacity expansion starting instruction, the main controller can check before the capacity expansion and check whether the current state of the storage array can implement the controller capacity expansion. For example: and judging whether the storage array operates normally, whether the controllers in the controller cluster in the storage array reach an upper limit, and the like. When it is determined that the storage array can perform expansion control, the main controller may prepare expansion configuration parameters required for expansion control. For example, an ID and an IP address assigned to the controller to be expanded may be prepared.
S201, when finding the controller to be expanded, obtaining the application information of the controller to be expanded.
In the embodiment of the present invention, referring to the structure diagram of a controller shown in fig. 3, each controller in a storage array may have an Expansion control module (EXP) built therein, and the Expansion control module may be used to implement automatic configuration of the configuration parameters of the controller of a cluster and the controller to be expanded, so as to implement a function of automatic Expansion control of the controller for the cluster. At ordinary times, the expansion control module of each controller is in a closed state, when an operation user performs expansion, the expansion control module of the main controller can be started to realize the function of automatically configuring the configuration parameters of the cluster and the controller to be expanded, and the expansion control modules of other controllers keep in a closed state. The expansion control module can be used for discovering the controller to be expanded through a UDP broadcast mechanism. Meanwhile, an IP address is distributed to the controller to be expanded; the expansion control module can also be used for generating new configuration parameters of the cluster during expansion control; the expansion control module can be further used for respectively issuing the new configuration parameters to the controller to be expanded and each controller of the cluster, and detecting whether the controller to be expanded is added to the cluster; the expansion control module can also be used for checking whether the current state of the storage array can implement expansion control of the controller before expansion control and checking whether the current state of the storage array is normal after expansion control; the expansion control module can also be used for realizing the interface communication function of issuing configuration parameters to the controller to be expanded and each controller in the cluster; the expansion control module can also be used for broadcasting information through a UDP broadcast mechanism; the expansion control module can also be used for controlling the working process of the main controller and providing an interface for an external module or a terminal to inquire the state of the expansion control process or the expansion control result.
In the embodiment of the present invention, referring to fig. 3, the controller may further include an SYS (System Control) module connected to the expansion Control module, and in order to distinguish the controller from the SYS module of the to-be-expanded controller described below, in the embodiment, the SYS module is represented by a first SYS module. The first SYS module is used for cluster management, and the expansion control module can realize functions of expansion control check, configuration generation, configuration execution and the like through the first SYS module. Can include the following steps: the expansion control module calls a first SYS module interface to carry out check before expansion control and verification after expansion control; the expansion control module can call a first SYS module interface to generate first configuration information and second configuration information required by expansion control; the expansion control module may invoke the first SYS module interface to modify the configuration of the cluster.
In the embodiment of the invention, the main controller can find the controller to be expanded through the expansion control module. And the expansion control module sends broadcast information through a UDP broadcast unit, wherein the broadcast information is used for discovering the controller to be expanded. When the controller to be expanded returns the application information according to the broadcast information, the expansion control module can receive the application information returned by the controller to be expanded. And the application information is used for applying for joining the cluster to the master controller.

The operation user can interact with the main controller through an input device of the terminal equipment connected with the management monitoring module, so that the operation user can send an operation instruction to the management monitoring module through the terminal equipment. The operation user can control the expansion control module through the management monitoring module. For example: the expansion control module is normally in a closed state, when an operation user needs to perform expansion, the operation user can send an expansion starting instruction to the management monitoring module through the terminal device, so that the management monitoring module obtains the instruction to control the expansion control module to start so as to prepare for automatic expansion of the cluster, wherein the expansion starting instruction can be used for starting the expansion control module. When the operation user starts the expansion control mode through the terminal device, the management monitoring module acquires the expansion starting instruction to start the expansion control module, and simultaneously monitors the operation process of the expansion control module, wherein the management monitoring module starts the expansion control module by sending the expansion starting instruction to the expansion control module, so that the expansion control module responds to the instruction to start. When the expansion control module receives the expansion starting instruction, the expansion control module can check before expansion control and check whether the current state of the storage array can implement expansion control of the controller. For example: and judging whether the storage array operates normally, whether the controllers in the controller cluster in the storage array reach an upper limit, and the like. The check before the expansion control by the expansion control module may be that the expansion control module calls an interface of a first SYS module of the controller to implement the check before the expansion control. After the storage array is judged to be capable of implementing expansion control, the expansion control module can prepare expansion configuration parameters required by the expansion control. For example: an ID assigned to the controller to be expanded, an IP address, and the like may be prepared. And when the expansion control check of the expansion control module is finished, the expansion control module can discover the controller to be expanded. The specific embodiment of the above can be referred to for the expanding and controlling module to find the controller to be expanded.

After the expansion control module generates the first configuration information and the second configuration information, the expansion control module may modify the configuration of the to-be-expanded controller and each controller of the cluster according to the first configuration information and the second configuration information. The expansion control module can broadcast the first configuration information in the cluster, so that the controller to be expanded, which is accessed to the cluster, is configured according to the first configuration information, and the configuration requirement of the cluster on the controller to be expanded is met. Further, the expansion control module can modify the configuration of each controller of the cluster by calling the first SYS module to modify the configuration of each controller of the cluster, so as to meet the configuration requirement for adding the controller to be expanded to the cluster.
In the embodiment of the invention, after the expansion control module modifies the configuration of the controller to be expanded and each controller of the cluster, the expansion control module can inform the first SYS module to add the controller to be expanded into the cluster.
