Problems solved by technology

[0004] However, the above solutions have the following problems: the memory capacity of nodes is limited, which is particularly insufficient compared to disk storage. When the amount of data is large, the memory space will be used up, resulting in business interruption

Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] The embodiment of the present invention relates to a method and device for increasing storage capacity, which is applied to the desktop cloud, and the desktop cloud uses memory as the main memory (i.e., the main memory), and by setting the expanded storage space as the emergency device of the memory, the capacity expansion is realized, and the business is not stable. interruption. Wherein, the extended storage space may be any type of storage device, including a volatile storage device or a non-volatile storage device, such as disk, SSD, memory, and the like. Preferably, a magnetic disk can be selected to avoid data loss in situations such as restart, shutdown or power failure, and reduce hardware costs. Of course, memory can a...

Abstract

The invention discloses a method and a device for expanding storage capacity, which are applied to a desktop cloud. A storage space of the desktop cloud comprises a memory and an extension storage space, and belongs to the field of communication. The method comprises the following steps of receiving a data storage request; judging whether the used storage space of the memory reaches the specified upper limit or not; when the used storage space of the memory does not reach the specified upper limit, storing the data into the memory; when the used storage space of the memory reaches the specified upper limit, storing the data in the extension storage space. The device comprises a receiving module, a judging module and a data storage module. The method and the device have the advantages that the capacity expansion is realized in the desktop cloud which uses the memory as the main memory, so the continuity of business IO (input / output) is guaranteed, and the non-interrupted effect of the business is guaranteed even when the usage of the memory reaches the upper limit.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for increasing storage capacity. Background technique [0002] The desktop cloud is a technology that separates the desktop environment of a personal computer from a physical machine through a cloud computing model, and it can provide desktop services externally. In the desktop cloud virtual desktop architecture (Virtual Desktop Infrastructure, referred to as: VDI), a domain on the server can virtualize the central processing unit (Central Processing Unit, referred to as: CPU), input and output (Input Output, referred to as: IO) bus, Resources such as storage are used by another domain on the server. Most of the data storage used in the desktop cloud is composed of disk arrays, a few are composed of solid state drives (Solid State Drives, referred to as: SSD) arrays, and very few are composed of memory as the main memory (ie, main memory). [0003] In the desktop c...
