Abstract: The embodiments of the present invention relate to a storage system comprising: a storage network; at least two storage nodes, connected to the storage network; and at least one storage device, connected to the storage network, each storage device comprising at least one storage medium; wherein, the storage network is configured to enable each of the at least two storage nodes to access any of the at least one storage medium without passing through another storage node of the at least two storage nodes. According to the embodiments of the present invention, a storage system in which there is no need to physically migrate data when rebalancing is required is provided.

Abstract: Embodiments of the present invention relate to a method and device for a virtual machine to access a storage device in a cloud computing management platform, which can solve the problem that, in the prior art, the virtual machine cannot be connected to the local storage device directly, but must be connected to the local storage device through the iSCSI protocol. The method includes: judging whether the storage device to be accessed by the virtual machine is on a same physical machine as the virtual machine; and when it is judged that the storage device is on the same physical machine as the virtual machine, mounting the storage device directly to the virtual machine.

Abstract: The embodiments of the present invention relate to a storage system comprising: a storage network; at least two storage nodes, connected to the storage network; and at least one storage device, connected to the storage network, each storage device comprising at least one storage medium; wherein, the storage network is configured to enable each storage node to access all the storage mediums without passing through other storage nodes. According to the embodiments of the present invention, a storage system in which there is no need to physically move data when rebalancing is required is provided.

Abstract: A system and method for electronic stamping are disclosed. Personal fingerprint pre-stored is used to verify the fingerprint information collected, the document data and the fingerprint information is signed with a private key to get a first signature result, the user's public key and the pre-stored fingerprint information is then signed with a private key of a stamp producer to get a second signature result, the first signature result, the collected fingerprint information and the second signature result are combined to form electronic fingerprint stamp data.

Abstract: A data storage system comprises at least one subsystem. Each subsystem includes at least two physical servers and at least two storage devices. Each physical server is connected to at least one storage device through a direct channel, and a part of storage medium in each storage device are used as a master storage area, another part of the storage medium in each storage device are used as a slave storage area. When data is written to the data storage system, the data is written to the master storage area of a certain storage device connected to a certain physical server in a certain subsystem, and is synchronized to the slave storage area of another storage device connected to anther physical server. A corresponding cloud serving method is disclosed.
