Description

Method, device, equipment and readable medium for distributing four-control environment memory
Technical Field
The present invention relates to the field of computers, and more particularly, to a method, apparatus, device, and readable medium for memory allocation in a four-control environment of devices with different memory configurations.
Background
In the full flash reduced pool storage function, dynamic memory allocation is used to dynamically allocate the memory used by the metadata management module, that is, if the full flash reduced pool is configured in the current system, the memory required by the metadata management module (Master Data Management, MDM, software component for managing metadata) is applied from the module through the DMM (Dynamic Memory Management, dynamic memory management module, as software component for managing device memory allocation), otherwise, the metadata management module does not work, and no memory is required to be applied.
Since the current DMM module manages a DMM Pool (which refers to a resource Pool managed by the dynamic memory allocation module) corresponding to an ID allocated to each module that adopts dynamic memory allocation, when the system is initialized, the DMM module already confirms that a DMM Pool corresponding to an ID is allocated to the metadata management module, and this DMM Pool information is already set according to the requirements of the metadata management module and cannot be changed any more, and the maximum memory allocation specification of the DMM Pool is already determined.
Each storage device contains two controllers that belong to the same IOGRP. In a four-control environment, there are two sets of storage devices, so the two storage devices belong to two different IOGRPs (input-output groups) in the same cluster. When the system memories of the two sets of storage devices are different, the memories required to be dynamically allocated by the metadata management module are also different, so that the controllers in the two different IOGRPs cannot use the DMM Pool corresponding to the same ID, namely, the existing design does not meet the memory application requirements of the metadata management module when the different memory devices form a four-control environment.

As shown in fig. 1, the method may include the steps of:

For example, there are a storage device a and a storage device B in the cluster, where the memory size of the storage device a is 128GB, including two controllers node1 and node2, the memory size of the storage device B is 256GB, including two controllers node3 and node4, and after the four-control environment is formed, two storages form a four-control cluster, in which case dmm_pool having different memory sizes need to be created in the cluster, for example, dmm_pool1 having 128GB memory, dmm_pool2 having 256GB memory, and dmm_pool3 having 512GB memory are created.
S2, responding to the controller initialization of the storage device, and selecting a corresponding DMM pool for initialization according to the memory size of the storage device.
When two controllers of the storage device a are initialized, since the memory of the storage device a is 128GB, dmm_pool1 having the same memory size is selected for initialization, and when the memory is used later, the memory is applied from dmm_pool1, and similarly, when two controllers of the storage device B are initialized, since the memory of the storage device B is 256GB, dmm_pool2 is selected for initialization, and when the memory is used later, the memory is applied from dmm_pool 2.
S3, in response to the completion of the initialization of the controller of the storage device, the metadata management module of the storage device sets configuration information in the initialized DMM pool.
After the device is initialized, when the metadata management module is set, the metadata management module of the storage device a selects information such as a parameter max_pool_size (maximum resource application number) in which dmm_pool1 is set, and the metadata management module of the storage device B selects information such as a parameter max_pool_size in which dmm_pool2 is set.
S4, responding to the establishment of the reduced pool in the cluster, and distributing memory to a metadata management module of the storage device from the DMM pool according to the owner of the established reduced pool.
Acquiring an input/output group corresponding to a storage device, judging information of an owner input/output group of a created compaction Pool, for example, the input/output group corresponding to a storage device A is IOGRP0, the input/output group corresponding to a storage device B is IOGRP 1, judging that the owner of the created compaction Pool is IOGRP0, and similarly, if the owner of the compaction Pool is IOGRP 1, the DMM module allocates memory to a metadata management module of the storage A from Dmm_Poo1, and if the owner of the compaction Pool is IOGRP 1, the DMM module allocates memory to a metadata management module of the storage B from Dmm_Poo2. If no reduced Pool is created in either IOGRP0 or IOGRP 1, the DMM module does not allocate memory from the corresponding Dmm_pool to the metadata module.
By the technical scheme, dynamic memory allocation can be realized under the condition that devices with different memory specifications build a four-control environment, and unknown errors caused by memory application of the metadata management module can be avoided.

For example, the cluster includes a storage device a and a storage device B, where the memory size of the storage device a is 128G, the memory size of the storage device B is 256G, dmm_pool1 with 128GB memory and dmm_pool2 with 256GB memory are created, and if dmm_pool3 with 512GB memory, the storage device a selects dmm_pool1 with 128GB memory to initialize, and the storage device B selects dmm_pool2 with 256GB memory to initialize.
In a preferred embodiment of the present invention, in response to a cluster consisting of storage devices of different memory configurations forming a four-control environment, creating a number of DMM pool in the cluster comprises:
in response to a cluster consisting of storage devices of different memory configurations, creating a number of DMM pool having different memory sizes in the cluster. For example, dmm_pool1 with 128GB memory, dmm_pool2 with 256GB memory, and dmm_pool3 with 512GB memory are created.
In a preferred embodiment of the invention, the configuration information includes maximum resource application number information.

acquiring an input/output group corresponding to the storage device;
judging the information of the input and output groups of the owners of the created reduced pool;
and distributing memory from the DMM pool to a metadata management module of the storage device corresponding to the information of the input/output group according to the information of the input/output group of the owner of the created reduced pool. For example, the input/output group corresponding to the storage device a is the IOGRP0, the input/output group corresponding to the storage device B is the IOGRP 1, and if it is determined that the owner of the created reduced Pool is the IOGRP0, the DMM module allocates memory to the metadata management module of the storage a from the dmm_pool1, and similarly, if the owner of the reduced Pool is the IOGRP 1, the DMM module allocates memory to the metadata management module of the storage B from the dmm_pool 2. If no reduced Pool is created in either IOGRP0 or IOGRP 1, the DMM module does not allocate memory from the corresponding Dmm_pool to the metadata module.
