Embodiment Construction

[0016] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0017] As can be seen from the accompanying drawings, the data block link characteristic testing method of the AEP memory of the program is characterized in that it includes the following steps: 1) creating a data block space according to the regionID of the APP mode of the AEP memory; 2) formatting the created data block space, and mount it in the system path; 3) Make an IO stream test configuration table, adjust the test data block size, capacity, depth, test duration, read and write through configuration parameters, and test and verify the data space disk; 4) Basis The test data space disk is named and imported into different test log collection documents; the test ends.

[0018] In step 1), first enable the App Direct mode feature function of the AEP memory, and form a correspond...

Abstract

The present invention provides a method for testing data block link characteristics of memory, comprising the following steps: 1) creating a data block space according to the regionID of the APP mode of AEP memory; 2) formatting the created data block space, and mounting it to the system In the path; 3) Make an IO stream test configuration table, adjust the test data block size, capacity, depth, test duration, read and write through configuration parameters, and test and verify the data space disk; 4) Import different data space disks according to the test The test log is collected in the document; the test is over. This method can effectively detect the data block link of the AEP memory, perform read and write operations, switch between different data block sizes and capacities, and collect test results.

Description

Technical field: [0001] The invention relates to a data block link characteristic testing method for AEP memory. Background technique: [0002] AEP memory, referred to as Apache Pass DIMMs, is designed for high performance and flexibility, The Optane TM DC persistent memory (DCPMM) is a new generation of DC persistent memory non-volatile memory module, which introduces Optane TM Media Technology Memory Media DDR4 form factor. The supported memory operation modes are Memory Mode (volatile) and App Direct (persistent memory). One of the basic features of the AEP memory test is the data block link test. The data block is a data space block. It is a flash memory space device block created based on the App Direct mode feature that can be used to store data streams. It has memory flash The characteristic that when the current is turned off, the stored data will not disappear from the computer memory. Since it is a data space block, when the data flow is IO, when the content ...
