CN105260281A - Iozone-based PCIE SSD card performance test method - Google Patents

Abstract

The invention discloses PCIE? The SSD card performance test method is characterized by comprising the following implementation processes: identify PCIE connected to the server through PCIE slot? An SSD; for PCIE? The SSD is partitioned, mounted and formatted; according to the actual configuration modification, transmitting the test parameters to the performance test script; and starting a performance test and outputting a result. The method improves the limitation of the iozone test command, and enriches the iozone test environment through the setting and modification of the early-stage test parameters and the configuration files. Can multiple PCIE's be addressed simultaneously? The SSD performs multi-mode read and write tests of multiple threads. The number of threads, the size of a test block, the size of a test file, the test mode and the like in the test process can be manually adjusted according to actual requirements. Can flexibly adjust the test parameters and configuration files of the iozone, and can be applied to a plurality of PCIE? The SSD card performs multiple modes of read and write testing of multiple threads.

Description

A kind of method of the PCIE SSD card performance test based on iozone

Technical field

The present invention relates to computer server technical field, be specifically related to a kind of method of the PCIESSD card performance test based on iozone.

Background technology

Along with the development of IT field technology, conventional informationization service and the increasingly powerful performance requirement of cloud computing service to server more and more higher.PCIESSD is as data carrier, and the entirety that its performance directly affects server presents.As server hardware supplier, when product development, more input is needed for the performance test of hard disk.

Shell script is similar to the batch processing under Windows/Dos, namely puts in advance in a file with all kinds of order, facilitates a program file of disposable execution, mainly facilitates keeper to carry out arranging or manage.But it is more powerful than the batch processing under Windows, than higher by the program efficiency of other programs editor.

Iozone is the benchmark instrument of a file system, can test the readwrite performance of different operating system file systems, can test Read, write, re-read, re-write, readbackwards, readstrided, fread, fwrite, randomread, pread, mmap, the performance of the hard disk under the pattern that aio_read, aio_write etc. are different.

But iozone only provides simple parameter, wall scroll iozone order has very large test to limit to, and as tested one piece of hard disk, p-wire number of passes controls difficulty etc.

Based on above-mentioned technology, if can shell script be passed through, revise test file according to real server configuration, and can manual adjustment member parameter, the hard disk performance test for diversified configuration offers convenience and higher efficiency by this.

Summary of the invention

The technical problem to be solved in the present invention is: for above weak point, and it is a kind of practical for providing, and can expand, make it the method adapting to diversified performance test demand to the test parameter of iozone.

The technical solution adopted in the present invention is:

Based on a method for the PCIESSD card performance test of iozone, the implementation procedure of described method is:

1) PCIESSD that book server is connected by PCIE slot is identified;

2) subregion is carried out to PCIESSD, carry and format;

3) according to actual disposition amendment, test parameter is passed to performance test script;

4) performance test is started, and Output rusults.

Described as follows by PCIE slot connection PCIESSD process:

Identify the PCIESSD that book server is all;

Judge input parameter number, when not meeting, export usage backed off after random;

Identify all drives.

It is described that test parameter to be passed to performance test script process according to actual disposition amendment as follows:

Determine the memory disc number of testing;

Test file size;

Test block size;

Test total Thread Count, the Thread Count according to each hard disk of hard disk quantity and input determines;

According to the Thread Count that each memory disc is tested, determine test file.

After described script is complete, in file with hddext4 beginning file for net result.

Beneficial effect of the present invention is:

The inventive method can carry out the readwrite performance test of the various modes of multiple thread simultaneously to multiple PCIESSD.Thread Count in test process, test block size, test file size, test pattern etc. all can carry out manual adjustments according to the actual requirements.Improve the restricted of iozone test command, by test parameter and the setting of configuration file and amendment in early stage, enrich the test environment of iozone.The readwrite tests of the various modes of multiple thread can be carried out to multiple PCIESSD simultaneously.Thread Count in test process, test block size, test file size, test pattern etc. all can carry out manual adjustments according to the actual requirements.Test parameter and the configuration file of iozone can be adjusted flexibly, multiple PCIESSD card is carried out to the readwrite tests of the various modes of multiple thread simultaneously.Thread Count in test process, test block size, test file size, test pattern etc. all can carry out manual adjustments according to the actual requirements.
