Description

BPS memory test method, system, terminal and storage medium based on Whitley platform

Technical Field

The invention relates to the technical field of memory testing, in particular to a method, a system, a terminal and a storage medium for testing a BPS memory based on a Whitley platform.

Background

BPS Memory, Barlow Pass, is another option Dimm from Intel corporation, and introduces a new Memory class layer, Persistent Memory or Persistent storage, which is a new Memory and storage technology designed for data center use, to extract more value from data. BPS memory can provide a perfect combination of high capacity, stability, and endurance compared to traditional memory. This amount of memory is intended to reduce latency and optimize memory, capacity and cost-constrained workloads. The operation modes of the BPS memory are mainly divided into 3 types: memory mode, APD mode, and Mix mode. The APD modes are divided into an interleaved mode and a not-interleaved mode. When the Memory mode is adopted, the Memory has the function of a Memory similar to a common Memory and can be used as the Memory; when the APD mode is adopted, the storage function is realized, and the device can be used as a hard disk; when the mode is the mixed mode, the function of the memory and the hard disk is simultaneously realized.

The Whitley platform is a platform which can support the operation and use of the BPS memory, can verify the performance and the function of the BPS memory and can fully exert the excellent characteristics of the BPS memory. For memory intensive workloads, the Whitley platform may support higher memory bandwidth and capacity. Each CPU comprises 8 DDR4 memory channels, the memory speed can reach 3200MT/s at most, and 16 DIMMs can be inserted. On the Whitely platform, there are various configurations of the BPS memory and the normal memory, such as: 8+8, 8+4, 4+4, 6+1, wherein the front of the + number is a common memory and the back is a BPS memory.

If the BPS memory is introduced and used on the Whitley platform, the compatibility between the BPS memory and the platform and the stability and reliability of the operation of the BPS memory on the platform need to be verified to the maximum extent. Therefore, performing a system test on the BPS memory is an important test for evaluating compatibility and stability, and a rebot test is an essential test in the system test. Most of the existing tests sequentially execute a rebot test, a pressure test and a memory MD5 value comparison test, and the test method consumes longer overall test time and has low test efficiency and complexity.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

FIG. 1 is a schematic flow diagram of a method of one embodiment of the present invention. The execution subject in fig. 1 may be a BPS memory test system based on the Whitley platform.

As shown in fig. 1, the method 100 includes:

step 110, equally dividing the BPS memory of the APD mode into a first whole disk and a second whole disk;

step 120, performing a reboot test on the Whitley platform server loaded with the BPS memory;

step 130, acquiring the MD5 value of the first whole disk after each restart, performing consistency proofreading on the MD5 value and a standard MD5 value, and recording a proofreading result;

and 140, carrying out IO pressure test on the second whole disk after each restart and recording a pressure test result.

In order to facilitate understanding of the present invention, the principle of the method for testing a BPS memory based on a Whitley platform according to the present invention is combined with the process of testing the BPS memory in the embodiment, and the method for testing a BPS memory based on a Whitley platform according to the present invention is further described below.

Specifically, the method for testing the BPS memory based on the Whitley platform includes:

and S1, equally dividing the BPS memory of the APD mode into a first whole disk and a second whole disk.

(1) And (3) matching a required test environment according to test requirements, upgrading the BPS memory FW (firmware) to a required version, and installing necessary tools required by the test, such as an ipmctl tool and an ndctl tool.

(2) The operation mode of the BPS memory is set to be an APD mode (interleaved). After the mode setting is successful, all namespaces in the mode are created and completely formatted into the EXT4 format. Some of the commands used are as follows: (1) a setting command # ipmctl create-high persistence memorytype ═ appdata of the APD mode; (2) creation command # ndctl create-namespace for namespace: (3) command # mkfx. etx4/dev/pmemX formatted as EXT4, where X is the device serial number corresponding to BPS memory namespace.

(3) The BPS memory is partitioned equally, i.e. two partitions with 50% of the total disk capacity are created. An example of a create command is as follows:

# paired-a optimal-s/dev/pmem 0 (or 1) - - -mklabel gpt

# divided-a optimal-s/dev/pmem 0 (or 1) - - -mkpart primary 0% 50%

# partitioned-a optimal-s/dev/pmem 0 (or 1) - - -mkpart primary% 0% -1

Where namespace 0.0 corresponds to the device pmem0 below it and namespace 1.0 corresponds to the device pmem 1.

And S2, carrying out reboot test on the Whitley platform server loaded with the BPS memory.

(1) Open/etc/rcd/rc. local file: local, then add an execute command to the last row, for example: sh-f/dev/nvme0p 2/dev/nvme 1p2-l 500-b arm &, wherein BPS _ reboot.sh is the name of a script and/root/Desktop is the path; -l is followed by the number of turns that need to be restarted; b is followed by a restart type, and war stands for rebot.

(2) And the test script and the rc.local file are endowed with execution authority, and then execution/etc/rc.local under the system is executed, so that reboot test of the server can be realized.

And S3, acquiring the MD5 value of the first whole disk after each restart, performing consistency check on the MD5 value and the standard MD5 value, and recording the check result.

The first whole disk performs acquisition, saving and verification of the MD5 value. Creating a folder corresponding to the partition under the mnt directory, for example: # mkdir-p/mnt/pmem 0p 1; # mkdir-p/mnt/pmem 1p 1. Then, the whole disk device corresponding to the partition is mounted in the corresponding folder, for example: # mount/dev/pmem0p1/mnt/pmem0p 1. The entire disk pmem0p1(pmem1p1) is mounted under the pmem0p1(pmem1p1) folder under the mnt directory. After the mount is completed, the file with the preset size can be written into the BPS memory, and this embodiment adopts a 20G file. For example: # dd if/dev/urandom of/mnt/pmem 0p1/testfile bs 1024k count 20000; # dd if/dev/urandom of ═ mnt/pmem1p1/testfile bs ═ 1024k count ═ 20000. After writing the large-capacity file into the first whole disk of the BPS memory, the acquisition, storage and later verification of the MD5 value are carried out. The acquisition and saving of MD5 values may be implemented with command # MD5sum/mnt/pmem0p1 (or pmem1p1)/testfile | awk '{ print $1 }'. This is followed by a check of the MD5 value, and a brief description of how this is done is as follows: the original MD5 value (MD 5 value obtained immediately after storing in a file) is used as the standard MD5 value, testfile is deleted each time it is started, and then the file is rewritten in the BPS memory, and new MD5 value is obtained and stored and compared with the standard MD5 value. The MD5 value obtained by each restart is consistent with the standard MD5 value, and the comparison result (consistent or inconsistent) between the MD5 value obtained by each restart and the standard MD5 value is written into a test log.

And S4, carrying out IO pressure test on the second whole disk after each restart and recording the pressure test result.

Carrying out IO pressure test to the whole dish of second after restarting at every turn, the load is pressed and is surveyed the use and is carried out pressure with the fio instrument, and the pressurization strategy indicates as follows: FIO-name _ mix _ random _1 jobjd 128-filename $ { FIO _ parameter _ LIST } - -ioengine ═ libaio-direct ═ 1-thread ═ 1-bs ═ 4 k-numjobs ═ 1-iodepth ═ 128-rw ═ range-rwmixread ═ 50-runtime ═ 1 h-time _ based ═ 1-size 100%, where $ { FIO _ parameter _ LIST } is/dev/pmem 0p2 or/dev/pmem 1p 2. And acquiring the random reading rate, the random writing rate, the sequential reading rate and the sequential writing rate in the pressure testing process, writing the acquired pressure testing result into a testing log and marking the testing times.

S5, acquiring initial performance state parameters of the CPU and the BPS memory before the start of the reboot test, for example, information of the CPU, basic information of the BPS memory, and a series of information such as namespace and region, and storing the initial performance state parameters as initial values. The initial performance state parameters of the system CPU and the BPS memory are collected after each restart, and can be set as test state parameters for obtaining for the convenience of detection. And comparing whether the restarted performance state parameters are consistent with the initial state parameters or not, and writing comparison results into the test log. And after the test is finished, outputting the performance state parameters with inconsistent comparison and the belonged test times.
