detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

An embodiment of the present invention provides a method for resource allocation, where the application is in a processing device, and the processing device is connected to at least one storage device through a memory bus, where the storage device includes at least two different types of storage media, as shown in the figure. As shown in Figure 1, the method includes:

101. The processing device receives, by using an acquiring interface, physical storage resource allocation request information sent by an application.

The physical storage resource allocation request information includes information about the size of the physical storage resource, the operation authority information for applying the physical storage resource, and the medium information for applying the physical storage resource. The media information includes performance information of physical storage resources that match data that needs to be stored.

Specifically, when the application needs to apply for the physical storage resource, the application function of the acquisition interface may be used to send the physical storage resource allocation request information to the processing device, and the processing device receives the physical storage resource allocation request information sent by the application through the acquiring interface. . That is, the application sends the physical storage resource allocation request information to the processing device in the form of parameters of the acquisition interface.

It should be noted that the parameters of the interface are the information about the physical storage resource, for example, the size information of the physical storage resource, the operation authority information of the physical storage resource, and the medium information of the physical storage resource.

102. The processing apparatus determines whether the physical storage resource allocation request information includes information about a medium type of a physical storage resource.

Specifically, after receiving the physical storage resource allocation request information, the processing device may The physical storage resource allocation request information is parsed, and if the information of the media type of the physical storage resource is parsed, it is determined that the physical storage resource allocation request information includes the information of the media type of the applied physical storage resource. If the information of the media type of the physical storage resource is not parsed, it is determined that the physical storage resource allocation request information does not include the media type information of the applied physical storage resource.

103. If it is determined that the physical storage resource allocation request information does not include information about a media type of the applied physical storage resource, the processing device searches for a storage medium that matches the media information in a pre-acquired spatial feature table. Types of.

All the storage medium types and corresponding performance information included in the storage device are recorded in the spatial feature table.

It should be noted that the spatial feature table is acquired when the storage device is connected. The performance information corresponding to each storage medium type in the storage device recorded in the spatial feature table may be information such as delay information, energy consumption information, stored data feature information, and persistent information. Of course, other performance information may also be recorded, which is not limited by the present invention.

Specifically, when the processing device determines that the physical storage resource allocation request information does not include the information of the media type of the applied physical storage resource, the media information for applying for the physical storage resource does not include the medium type for applying the physical storage resource. The space feature table may be searched according to the media information of the physical storage resource requested by the physical storage resource allocation request information, so that the type of the storage medium matching the media information of the applied physical storage resource may be found in the spatial feature table, and then the phase is The matching storage media type is determined as the media type of the application's physical storage resource.

It should be noted that, when the media information of the physical storage resource does not include the media type information of the physical storage resource, the media information includes only the performance information of the physical storage resource that matches the data that needs to be stored. The performance information may be data persistence performance information, and/or delay feature information, and/or power consumption feature information, and/or feature information of the data to be stored, and the like. At this time, the processing device may determine, according to the media information of the physical storage resource, the storage medium that satisfies the media information of the applied physical storage resource by searching the spatial feature table, that is, determining the media type for applying the physical storage resource.

It should be noted that the performance information of the physical storage resource may also be a performance parameter, which is not limited by the present invention.

Exemplarily, a storage medium DRAM (Dynamic Random Access Memory) is recorded in a spatial feature table acquired by the processing device in advance, and NVM is recorded. (Non-Volatile Memory, non-volatile memory), disk and its corresponding performance information. If the media information of the applied physical storage resource carried in the physical storage resource allocation request information is delayed by less than the first preset value, the processing device receives the physical storage resource allocation request information and parses the information, and then determines The media type of the requested physical storage resource is not included in the physical storage resource allocation request information. The processing device searches for the pre-acquired spatial feature table according to the media information of the physical storage resource, and determines a storage medium whose delay is less than the first preset value. If it is DRAM, it can determine that the media type of the applied physical storage resource is DRAM. .

It should be noted that the first preset value is preset.

104. Allocate an available virtual resource to the application according to the size information of the application physical storage resource.

Specifically, after determining the type of the medium for applying the physical storage resource, the processing device may allocate the available virtual resource of the corresponding size to the application according to the size information of the applied physical storage resource.

105. Allocate, according to the physical storage resource allocation request information and the media type of the application physical storage resource, an available physical storage resource corresponding to the available virtual resource.

Specifically, the processing device allocates the available physical storage resources corresponding to the available virtual resources to the application according to the physical storage resource allocation request information and the media type of the applied physical storage resource, according to the storage device connected to the processing device. The method is different.

When the connected storage device can allocate the available physical resources corresponding to the available virtual resources to the application according to the physical storage resource allocation request information and the media type of the application physical storage resource, the processing device only needs to The physical storage resource allocation request information and the media type of the application physical storage resource are sent to the storage device, and the storage device allocates an available physical storage resource corresponding to the available virtual resource to the application. That is, the processing device allocates an available physical storage resource corresponding to the available virtual resource to the application through the storage device.

When the connected storage device can allocate the available physical resources corresponding to the available virtual resources to the application according to the physical storage resource allocation request information and the media type of the application physical storage resource, the processing device itself The physical storage resource allocation request information and the media type of the application physical storage resource are application allocation and location The available physical storage resources corresponding to the available virtual resources.

An embodiment of the present invention provides a method for allocating resources, and receiving, by the acquiring interface, physical storage resource allocation request information sent by an application, where the physical storage resource allocation request information includes size information of applying for physical storage resources, and applying for physical storage resources. The operation authority information and the medium information of the application physical storage resource; determining whether the physical storage resource allocation request information includes the information of the media type for applying the physical storage resource.
