In a specific embodiment of the present invention, after receiving first storage data sent by a primary storage server and second storage data sent by a block synchronization storage server, an ethernet switch may first parse the first storage data and the second storage data, and obtain, in the first storage data, an equipment identifier of the primary storage server and data to be stored; simultaneously acquiring the equipment identification of the block synchronous storage server and the data to be stored in the second storage data; then the ethernet switch can judge whether the data to be stored in the first storage data is the same as the data to be stored in the second storage data; when the data to be stored in the first storage data is the same as the data to be stored in the second storage data, the ethernet switch may store the first storage data or the second storage data. That is, when the data to be stored in the first storage data is the same as the data to be stored in the second storage data, the ethernet switch stores either the first storage data sent by the primary storage server or the second storage data sent by the block synchronization storage server, instead of storing the first storage data and the second storage data at the same time. When the data to be stored in the first storage data is different from the data to be stored in the second storage data, the Ethernet switch stores the first storage data and the second storage data at the same time.
According to the cloud storage method provided by the embodiment of the invention, a user side firstly sends data to be stored to a main storage server and a block synchronous storage server; the main storage server stores the data to be stored as first storage data and sends the first storage data to the Ethernet switch; the block synchronous storage server stores the data to be stored as second storage data and sends the second storage data to the Ethernet switch; the Ethernet switch receives the first storage data and the second storage data and stores the first storage data or the second storage data. That is to say, in the technical solution of the present invention, the primary storage server and the block synchronous storage server may store the data to be stored as the first storage data and the second storage data, respectively, and then the primary storage server and the block synchronous storage server send the first storage data and the second storage data to the ethernet switch, respectively. And the existing cloud storage system includes: the system comprises a user side, a cloud storage server and an Ethernet switch; when the cloud storage server fails, the high availability of the cloud storage system cannot be guaranteed. Therefore, compared with the prior art, the cloud storage method provided by the embodiment of the invention can realize high availability of the cloud storage system; moreover, the technical scheme of the embodiment of the invention is simple and convenient to realize, convenient to popularize and wider in application range.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
