Detailed Description
Referring to fig. 1, the embodiment of the present application provides a possible application scenario in which a dual-control storage device is disposed.
The dual-Control storage device includes a first controller 110 and a second controller 120, and heartbeat detection is performed between the first controller 110 and the second controller 120 through a TCP/IP (Transmission Control Protocol/Internet Protocol). The first controller 110 manages the first storage resource 111 through PCIE/SATA/SAS (peripheral component interconnect express/Serial Advanced Technology Attachment/Serial Attached SCSI, high speed Serial computer expansion bus standard/Serial hard disk/Serial SCSI Technology); the second controller 120 manages the second storage resources 121 through PCIE/SATA/SAS. Also, the first memory 112 is provided for the first controller 110 for temporarily storing resources, and the second controller 120 is provided with the second memory 122 for temporarily storing resources.
In addition, the first Memory 112 and the second Memory 122 may be a built-in storage device, such as a built-in SSD (Solid State Disk), an external storage device, or other storage Media, such as a DOM Disk (DOM Disk), an eMMC (Embedded Multi Media Card), a hard Disk, a Flash (Flash EEPROM Memory), and the like.
Based on the application scenario of the dual-control storage device, the dual-control storage device comprises a dual-control active mode and a dual-control active-standby mode.
In dual active mode, the first controller 110 and the second controller 120 respectively operate storage services, wherein the storage services represent services to which data is stored on some medium and which can be guaranteed efficient access. For example, the first controller 110 processes storage services of 128 channels of IPC (Inter-Process Communication) audio/video pull streams, and at the same time, the second controller 120 processes storage services of another 128 channels of IPC audio/video pull streams, and if an abnormality occurs in the first controller 110, the second controller 120 may manage the storage services of the 128 channels of IPC audio/video pull streams originally processed by the first controller 110, that is, at this time, the second controller 120 processes storage services of 256 channels of IPC audio/video pull streams in total. The audio/video pull stream represents a process of pulling audio or video content by using a specified address.
In the dual-control active/standby mode, if the first controller 110 is a main controller and the second controller 120 is a standby controller, the first controller 110 is used to process storage services of 256 IPC audio/video pull streams, and the second controller 120 does not need to process any storage services. When the first controller 110 is abnormal, the second controller 120 will process the storage service of 256 IPC audio/video pull streams originally processed by the first controller 110, and will take over all the storage resources managed by the first controller 110.
Based on the application scenario, the embodiment of the application provides a method and a device for dual-control storage switching and an electronic device, which solve the problem of risk of data loss in the dual-control switching process in the prior art.
The method provided by the embodiment of the application is further described in detail with reference to the attached drawings.
Referring to fig. 2, an embodiment of the present application provides a method for dual-control storage switching, which includes the following specific processes:
step 201: when a first controller is abnormal, determining whether a first storage resource of the first controller is taken over by a second controller to be in a ready state;
when the first controller is abnormal, determining whether the data of the first storage resource is synchronized to the second controller: if not, the first memory of the first controller is in a non-ready state; if so, the first memory of the first controller is in a ready state.
Specifically, when the dual-control storage device finds that the first controller is abnormal, the first service data and the first storage resource of the first controller are all taken over by the second controller, where the first storage resource may represent a storage capacity and may also be used to store the first service data, where the first service data is data representing a storage service.
After confirming that the second controller takes over the first storage resource, there is a process of dual-control switching: the first storage resource is first correctly identified by the second controller, and then data and the like stored in the first storage resource before the first controller is abnormal need to be synchronously written into the second controller. Here, the synchronization data is to obtain information related to the first storage resource, for example, if the first controller writes a part of the first storage resource before the abnormal state, the second controller takes over and then should continue writing the first storage resource from which position, and the second controller needs to specify the file system structure, the remaining storage capacity, and the like in the first storage resource.
And finally, determining whether the first storage resource is in a ready state according to the judgment of whether the double-control switching process is finished: if the operation is finished, the operation is in a ready state; if not, the state is not ready.
Step 202: writing traffic data generated during a not ready state into a second memory of a second controller when the first storage resource is in a first not ready state;
in order to ensure that the first service data generated during the first non-ready state of the first storage resource can be timely and completely stored, in the embodiment of the present application, a second memory of the second controller is used for temporarily storing the first service data generated during the first non-ready state.
Specifically, if it is determined that the first storage resource is in the first not-ready state, all the first traffic data generated during this period is written into the second memory for temporary storage, for example, the first traffic data is written into the second controller built-in SSD for temporary storage.
Step 203: writing traffic data generated during a ready state to the first storage resource when the first storage resource is in a first ready state.
After the dual-control switching operation is completed, it can be confirmed that the first storage resource is in a ready state, that is, the first storage resource can resume saving the first storage service. Then the first service data can be restored to be written into the first storage resource for saving from the time the first storage resource enters the ready state, and is not temporarily saved by being written into the second storage resource.
Specifically, if it is determined that the first storage resource is in the ready state, all the first service data regenerated from entering the ready state will be written into the first storage resource.
Further, in order to ensure that the first service data is not lost in the first storage resource that is taken over again after the first controller returns to normal, the first service data temporarily stored in the second memory during the above dual-control handover needs to be written back to the first storage resource.
In other words, in the embodiment of the present application, it is determined whether the second controller is idle, and when the second controller is idle, for example, a Central Processing Unit (CPU) of the second controller is idle or an Input/Output (Input/Output) is idle, the first service data in the second memory is written into the first storage resource.
Specifically, a load pressure value of a second controller is determined currently, and if the load pressure value of the second controller does not exceed a preset threshold value, first service data in a second memory is written into a first memory resource; and if the load pressure value of the second controller exceeds the preset threshold, stopping writing the data and acquiring the load pressure value again.
In addition, in the process of switching the storage of the second controller when the first controller is abnormal, the second service data and the second storage resource belonging to the second controller are not affected by the switching and are kept in stable storage.
By the method, the risk of data loss does not exist in the process that the second controller takes over the first storage resource and the first service data when the first controller is abnormal.
If the first controller recovers from the abnormal state, a dual-control handover management process is also required, and the principle thereof is the same.
Specifically, when the first controller returns to normal, it is determined whether the first storage resource taken over back by the first controller is in an not-ready state: writing the traffic data generated during the not-ready state into a first memory of the first controller when the first storage resource is in a second not-ready state; when the first storage resource is in the second ready state, writing the business data generated during the ready state into the first storage resource.
Further, it may also be determined whether the first controller is idle, and when the first controller is idle, such as a CPU of the first controller is idle or an I/O is idle, the first service data in the first memory is written into the first storage resource.
By the method, under the condition of not consuming memory resources, reliable, continuous and safe storage of data in the double-control switching process is effectively guaranteed, the availability of safe storage of actual data is enhanced, and great loss caused by data loss is avoided.
Based on the same inventive concept, the present application further provides a dual-control switching storage device, which is used to continuously and safely store data, solve the problem of risk of data loss in the dual-control switching process in the prior art, effectively ensure reliable, continuous and safe storage of data in the dual-control switching process under the condition of not consuming memory resources, enhance availability of data safe storage, and avoid major loss caused by data loss, and the device includes:

In one possible design, the confirmation module 301 is specifically configured to determine that the second controller takes over the first storage resource of the first controller when the first controller is abnormal; determining whether data of the first storage resource taken over by the second controller is synchronized into the second controller; if not, the first storage resource of the first controller is in an un-ready state; if so, the first storage resource of the first controller is in a ready state.
In one possible design, after the writing module 302, writing the service data in the second memory to the first memory resource is further included when the second controller is idle.
In a possible design, when the second controller is idle, writing the service data in the second memory into the first memory resource, specifically, to obtain a load pressure value of the second controller; judging whether the load pressure value exceeds a preset threshold value or not; if so, acquiring the load pressure value again; and if not, writing the service data in the second memory into the first memory resource.
In a possible design, after writing the service data in the second memory into the first storage resource when the second controller is idle, determining whether the first storage resource is taken over by the first controller in an not-ready state when the first controller returns to normal; writing traffic data generated during a not-ready state into a first memory of a first controller when the first storage resource is in a second not-ready state; writing traffic data generated during the ready state to the first storage resource when the first storage resource is in a second ready state.
In one possible design, after writing the traffic data generated during the ready state into the first storage resource when the first storage resource is in the second ready state, the method further includes writing the traffic data in the first memory into the first storage resource when the first controller is idle.
Based on the device, the reliable, continuous and safe storage of data in the double-control switching process is effectively realized under the condition of not consuming memory resources, the problem of data loss in the double-control switching process in the prior art is solved, the usability of safe data storage is enhanced, and the major loss caused by data loss is avoided.
