Detailed Description
The core of the invention is to provide a method for using a solid state disk, which effectively reduces the time consumption for acquiring the information of a zone, and further can conveniently and rapidly use a ZNS SSD.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of an implementation of a method for using a solid state disk according to the present invention, where the method for using a solid state disk may include the following steps:
step S101: a report zone request issued by a host is received.
Typically, the report zone request issued by the host carries quantity information and type information. The solid state disk of the application can be specifically a ZNS SSD.
Step S102: a storage space is applied as a target storage space.
The size of the target storage space can be set and adjusted according to actual needs, and when the P storage spaces are applied subsequently, the size of each storage space in the P storage spaces can also be set and adjusted according to actual needs. I.e. the target storage space and the P storage spaces are all the same size in one embodiment of the invention. Further, in practical applications, the sizes of the target storage space and the P storage spaces may be 4k according to practical experience, and the application will be described hereinafter by taking 4k as an example, it will be understood that in other situations, the sizes of the target storage space and the P storage spaces may have other values, but it should be noted that, in general, the selectable value is an integer multiple of 0.5 k.
Step S103: and continuously selecting the zone info meeting the report zone request by traversing each zone info until the preset stopping condition is met.
zone info is information of a zone, and specifically refers to configuration information of a zone, whether the configuration information of a zone accords with a report zone request issued by a host, and whether the type in the configuration information of the zone accords with the type requirement of the report zone request, namely, whether the type information is consistent with the type information carried in the report zone request.
And traversing each zone info, selecting the zone info conforming to the report zone request, and discarding the zone info not conforming to the report zone request until a preset stop condition is met.
It should be emphasized that, instead of executing step S104 after step S103 is completed, step S104 is triggered immediately after step S103 is triggered, that is, the solution of the present application is to continuously select zone info meeting the report zone request, and immediately fill the corresponding storage space after the zone info is selected. Step S103 and step S104 are performed simultaneously, and when step S105 is triggered, step S103 and step S105 are also performed simultaneously.
Step S104: when the part outside the reserved area of the target storage space is not fully filled, continuously placing the continuously selected zone info which accords with the report zone request into the target storage space until the part outside the reserved area of the target storage space is fully filled; the 1 st to nth bytes of the target storage space are reserved areas of the target storage space, so that the zone info is placed from the (n+1) th byte of the target storage space.
It will be appreciated that when steps S103 and S104 are initially triggered, the target storage space is empty, and then the portion outside the reserved area of the target storage space is gradually filled as zone info conforming to the report zone request is continuously selected.
When the selected zone info is placed in the target storage space, the zone info cannot be placed in the reserved area, specifically, the zone info is placed from the n+1th byte of the target storage space, because the reserved area needs to be used for placing the information head, namely the zone info header, and the specific content of the zone info header needs to be determined after all zone info uploaded at this time is determined.
It should be emphasized that, after the portion outside the reserved area of the target storage space is filled, the data in the target storage middle is not directly uploaded, and the data in the target storage middle needs to be uploaded after the information header is filled later.
In addition, in the case of a very small portion, there is a possibility that the portion other than the reserved area of the target storage space is not fully filled, and the stop condition is satisfied, and for this case, the step S105 is not required to be triggered, and the step S106 may be directly triggered.
Step S105: after the part outside the reserved area of the target storage space is fully filled, utilizing the P storage spaces applied in sequence to place the continuously selected zone info meeting the report zone request until the stopping condition is met, and not selecting new zone info; after the application of the storage space, the zone info is put in from the 1 st byte of the storage space, when the storage space is fully filled and the stop condition is not met, the data in the storage space is uploaded to the host and the next storage space is applied, and when the stop condition is met in the process of putting the storage space into the zone info, the data in the storage space is uploaded to the host.
As described above, the target storage space and P storage spaces are each 4k in size. After the portion outside the reserved area of the target storage space is fully filled, the present application applies for 1 storage space of 4k again, which is called 1 st storage space for convenience of description. It will be appreciated that when the 1 st storage space is just applied for, the 1 st storage space is empty, and then the continuously selected zone info meeting the report zone request is placed into the 1 st storage space, so as to gradually fill the 1 st storage space.
After the 1 st storage space is filled, the data in the 1 st storage space is immediately uploaded.
Assuming that after the 1 st storage space is filled, the stop condition is not satisfied, i.e. a new zone info meeting the report zone request is still selected, the present application applies for 1 more 4k storage space, which is called 2 nd storage space, while uploading the data in the 1 st storage space. And the same as the 1 st storage space, the 2 nd storage space is empty when the application is finished, and then the 2 nd storage space is gradually filled up along with the continuously selected zone info which accords with the report zone request being placed in the 2 nd storage space. After the 2 nd storage space is filled, the application immediately uploads the data in the 2 nd storage space.
And so on. For example, in a specific case, after the 6 th storage space is applied, in the process of placing the continuously selected zone info meeting the report zone request into the 6 th storage space, the stopping condition is satisfied, that is, a new zone info is not selected any more, where P is 6, at this time, the data in the 6 th storage space can be uploaded to the host, and then step S106 is triggered.
The specific content of the stopping condition can be set and selected according to actual needs, for example, in one specific embodiment of the present invention, the stopping condition is:
traversing each zone info and selecting zone info to meet the number of report zone requests, wherein at least one of the two conditions is satisfied.
That is, when all zone info is traversed, the selection of new zone info is stopped, and the number of selected zone info already meets the number of request of report, and the traversal is stopped, so that the new zone info is not selected any more.
Further, in a specific embodiment of the present invention, the method may further include:
for any 1 storage space in the P storage spaces, the release of the storage space is performed after uploading the data in the storage space to the host.
For example, in the foregoing embodiment, after uploading the data in the 1 st storage space, the solid state disk is not required to store the data in the 1 st storage space, so that the 1 st storage space can be released.
Step S106: after the stopping condition is met, the information head is filled into a reserved area of the target storage space, data in the target storage space is uploaded to the host, and response to the report request is completed, so that the host can use the solid state disk.
After the stop condition is met, it is indicated that no new zone info is selected any more, for example, in the foregoing example, in the process of placing the continuously selected zone info meeting the report zone request into the 6 th storage space, the stop condition is met, and then the data in the 6 th storage space is uploaded to the host, and step S106 is triggered.
After step S106 is triggered, the information header needs to be filled into the reserved area of the target storage space, and the size of the reserved area can be set according to actual needs, that is, the value of N can be set according to needs, and in actual application, the value of N is generally set to 64. I.e., the first 64 byte region is the zone info header.
After the information header is filled into the reserved area of the target storage space, the data in the target storage space can be uploaded to the host, that is, the uploading of the target storage space is later than the P storage spaces uploaded before, and the uploading is last.
After the data in the target storage space is uploaded, the target storage space can be released, so that the fact that the data which need to be uploaded at this time are all uploaded is described, namely, the response to the report zone request is completed, and the host can use the solid state disk.
In addition, in practical application, the method may further include:
after receiving a report zone request issued by a host, before applying for a storage space as a target storage space, selecting whether to execute a prp list acquisition process according to a first instruction of the host.
Specifically, in practical application, whether to execute the prp list acquisition process is determined according to the data volume to be uploaded by the solid state disk. The host may issue a first instruction including prp0 or prp1, for example, prp0 indicates that the prp list acquiring process is not required to be executed, prp1 indicates that the prp list acquiring process is required to be executed, and if the prp list acquiring process is required to be executed, a DMA request may be sent to the host, and the prp list is acquired and stored in the solid state disk.
By applying the technical scheme provided by the embodiment of the invention, the applicant considers that the time consumption for acquiring the information of the zone is longer in the traditional scheme, because in the traditional scheme, after all the information of the required zone is selected through traversing, uploading is started to the host, and particularly when the information of the required zone is more, the condition that the time consumption of the traditional scheme is longer is obvious. In the scheme of the application, the strategy of selecting and uploading is adopted, so that time consumption is saved. Specifically, after receiving a report zone request issued by a host, the application applies for a storage space as a target storage space, and then continuously selects zone info conforming to the report zone request by traversing each zone info until a preset stop condition is met. It will be appreciated that at the beginning, the target storage space of the application is empty, so that the continuously selected zone info meeting the report zone request is placed in the target storage space until the portion outside the reserved area of the target storage space is filled. After the part outside the reserved area of the target storage space is fully filled, the uploading of the target storage space cannot be directly performed, because the uploading of the target storage space can be performed only after the information head is filled into the reserved area of the target storage space, unlike the P storage spaces which are sequentially applied subsequently. After the part outside the reserved area of the target storage space is fully filled, the application places the continuously selected zone info meeting the report zone request by using the P storage spaces applied in sequence until the stopping condition is met and no new zone info is selected. And, to arbitrary 1 memory space in P memory spaces, when this memory space is filled up and stop condition does not establish, this application is direct with the data upload in this memory space to host computer and apply for next memory space, that is to say, this memory space as long as self is filled up, just can directly carry out the uploading of data, can not influence and put into the zone info that constantly selects out to the memory space of new application, promptly, make the uploading of the scheme data of this application and the selection of data can go on simultaneously. After the uploading of the data in the P storage spaces and the target storage space is completed, the response to the report request is completed, so that the host can use the solid state disk. From the above, the scheme of the application effectively reduces the time consumption for acquiring the information of the zone, and can further conveniently and rapidly use the ZNS SSD.
