Description
Technical field
The present invention relates to performance of disk arrays measuring technology, the specifically disk based on Linux distributed systems
Can test system and method.
Background technology
With the high speed development of memory technology, disk array has been widely used in scientific algorithm, affairs are handled online, VOD
（Video on Demand, video request program）Etc. in all multipair processing speeds, capacity and the higher application of reliability requirement.In order to
Disk array is preferably met the needs of various application environments, the evaluation and test of disk array progressive is just seemed particularly using preceding
It is important.Performance of disk arrays tests the IOPS that can mainly reflect disk array（Input/Output Operations Per
Second, I/O operation number per second）, the index such as average response time and data transmission rate, to network storage design and practical application
All there is great importance, thus it is great to the Research Significance of performance testing tool.
At present, some existing researchs are tested performance of disk arrays both at home and abroad, occur some typical test and appraisal specifications and
Evaluation tool, such as SPC（Storage Performance Council, storage performance council）、IOMeter、IoZone、
Bonnie++ and PostMark etc..Above testing tool respectively has its advantage and defect.SPC is test and appraisal base very authoritative both at home and abroad
Standard, but to use its testing tool need to add and SPC member and buy, costly and formality is complicated, be unfavorable for it is personal or in
Small enterprise uses, and SPC main analogs are different types of is served by, and can not carry out peak value test to storage system.Due to
Have under the optimisation strategy of file system, the actual performance of disk array can not be measured, so the performance test to disk array
Block level IO should be based on to ask, and PostMark, IOZone, Bonnie++ are based on file system level I/O request, can not meet
The demand of performance of disk arrays test.IOMeter can be based on file system or raw device IO and test, but its control terminal must be
Windows operating system run, this makes troubles to the unified management and monitoring of distributed measuring system, and IOMeter without
Method preserves the test result under renewal frequency.
