It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Fig. 1 shows a flowchart of a first data storage method according to an embodiment of the present invention, in which a processing procedure of a cloud disk system is taken as an example for description.
As shown in fig. 1, in this embodiment, the processing procedure of the cloud disk system may include the following steps:
step S101: receiving data to be stored sent by a client, and reading current storage configuration information;
here, the current storage configuration information is fixed for a period of time, and when a storage configuration information modification instruction sent by the client is received, the current storage configuration information is modified according to the storage configuration information modification instruction.
Specifically, the current storage configuration information includes which server the data to be stored is stored to, and an IP address, a port number, a domain name, and the like for accessing the server.
Step S102: calling a current data storage processing interface corresponding to the current storage configuration information according to the corresponding relation between the pre-stored storage configuration information and the data storage processing interface;
here, a rule for setting the data storage processing interface corresponding to the storage configuration information is preset, and the current data storage processing interface is determined according to the current storage configuration information.
Step S103: determining current cloud storage corresponding to the current data storage processing interface according to the corresponding relation between the pre-stored data storage processing interface and the cloud storage;
specifically, the current cloud storage is determined, and a cloud storage is obtained according to a given rule of what data storage processing interface corresponds to what cloud storage.
Here, the cloud Storage includes Ceph (three services of Object Storage, file Storage, and block Storage) which is abroad, Amazon S3 (i.e., Simple Storage Service) and Openstack Swift (Object Storage Service) which are provided), and OSS (Object Storage Service) which is provided by the ariloc cloud which is domestic, and the like.
Step S104: and writing the data into the current cloud storage through the current data storage processing interface.
As can be seen from the above description, according to the data storage method of the present invention, the data to be stored is written into the current cloud storage corresponding to the current data storage processing interface according to the current storage configuration information, so as to implement dynamic storage of the data, and the current cloud storage can be set according to actual needs, so that the data storage manner is diversified, and the data storage flexibility is improved.
In addition, in a specific example, when a data reading instruction sent by the client is received, a current data storage processing interface corresponding to the current storage configuration information is called according to the correspondence between the storage configuration information and the data storage processing interface;
determining the current cloud storage corresponding to the current data storage processing interface according to the corresponding relation between the data storage processing interface and the cloud storage;
and reading data corresponding to the data reading instruction from the current cloud storage through the current data storage processing interface.
And reading the current configuration information, calling a related data storage processing interface according to the storage scheme, reading data from the corresponding cloud storage, and returning the data to the client.
In addition, in a specific example, when a storage configuration information modification instruction sent by the client is received, modifying the current storage configuration information according to the storage configuration information modification instruction;
calling a target data storage processing interface corresponding to the modified storage configuration information according to the corresponding relation between the storage configuration information and the data storage processing interface;
determining target cloud storage corresponding to the target data storage processing interface according to the corresponding relation between the data storage processing interface and the cloud storage;
migrating the data from the current cloud storage to the target cloud storage through the current data storage processing interface and the target data storage processing interface.
The traditional cloud disk system stores data based on a cloud storage solution, if the storage solution is changed, the data storage processing interface used in the cloud disk system needs to be manually changed and integrally migrated, otherwise, user data cannot be accessed, and the adjustment difficulty is high.
When the configuration information is changed, the invention completes the migration of data among different storage systems according to the changed storage configuration information without manual operation, thereby saving time and labor and improving the flexibility of data storage.
In addition, in a specific example, before the reading the current storage configuration information, the method further includes the steps of:
and caching the data.
The cache system is a memory chip on the hard disk controller, has extremely high access speed, and is a buffer between the internal storage of the hard disk and an external interface. The internal data transmission speed of the hard disk is different from the transmission speed of the external interface, so that the cache plays a role of buffering. The size and speed of the cache are important factors directly related to the transmission speed of the hard disk, and the overall performance of the hard disk can be greatly improved. When the hard disk accesses the fragmented data, the data needs to be exchanged between the hard disk and the memory continuously, if a large cache exists, the fragmented data can be temporarily stored in the cache, the load of an external system is reduced, and the transmission speed of the data is also improved.
In addition, in a specific example, the data storage method further includes the steps of:
displaying a completion ratio of migrating the data from the current cloud storage to the target cloud storage.
In addition, in a specific example, after the data is migrated from the current cloud storage to the target cloud storage, the method further comprises the steps of:
and returning a result of the completion of the client data migration.
After the data migration between different storage systems is completed, a data migration completion result is sent to the client, and the client confirms the completion of the data migration according to the result, so that the subsequent processing can be performed, and the actual application requirements can be met.
Further, in one particular example, the current cloud storage is a file system or Ceph or Amazon S3 or Openstack Swift or ali cloud OSS.
Here, current cloud storage is set according to actual needs, and compared with a traditional cloud disk system which stores data based on a cloud storage solution, the cloud disk storage system provides multiple storage solutions and improves the flexibility of cloud disk storage.
In order to better understand the above method, an application example of the data storage method of the present invention is described in detail below.
In this embodiment, a bidirectional interaction process between the cloud disk system and the client is taken as an example for explanation, and this explanation is not intended to limit the scheme of the present invention.
As shown in fig. 2, the present embodiment may include the following steps:
