Embodiment Construction

[0019] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples.

[0020] The inventor noticed during the invention that:

[0021] In the current prior art, if the same physical storage space is to be shared, different address spaces are assigned to different processors, usually by means of software to logically separate the storage space to form different logical storage spaces. This approach requires some changes to the operating system and software.

[0022] The disadvantage of this solution is that changes to the operating system and software will inevitably bring about some compatibility and stability issues, and a large labor cost will be required for la...

Abstract

The present invention provides a storage controller and a method for using the storage controller, including each processor sending a storage instruction, the processor controller receiving the storage instruction sent by the processor, and sending it to a switch, and the switch sends it one by one to the hard disk control The hard disk controller sends the stored address space to the hard disk according to the address space indicated in the storage instruction, wherein the indicated address space is the address space allocated to the processor that issues the storage instruction. By adopting the technical scheme of the present invention, it is possible to ensure that multiple processors store instructions to reuse the same physical storage space under the time-sharing mechanism, thereby achieving the purpose of realizing multiple processors sharing the same physical storage space by means of hardware.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a storage controller and a method for using the same. Background technique [0002] With the development of cloud computing technology, virtualization technology is the core technology supporting cloud computing, and its application mode has changed from the initial server integration virtualization to the current desktop virtualization, network virtualization, storage virtualization and so on. The technical value and application space of virtualization technology in the field of cloud computing is constantly expanding. [0003] In the current prior art, the storage space is logically separated by means of software to form different logical storage spaces. [0004] The disadvantage of the prior art is that it is necessary to modify the operating system and software to allocate different address spaces for different processors. Contents of the invention [0005] The present ...
