It has support for 19 | +| | different types of I/O engines (sync, mmap, libaio, | +| | posixaio, SG v3, splice, null, network, syslet, guasi, | +| | solarisaio, and more), I/O priorities (for newer Linux | +| | kernels), rate I/O, forked or threaded jobs, and much more. | +| | | +| | (fio is not always part of a Linux distribution, hence it | +| | needs to be installed. As an example see the | +| | /yardstick/tools/ directory for how to generate a Linux | +| | image with fio included.) | +| | | ++--------------+--------------------------------------------------------------+ +|test | fio test is invoked in a host VM with a volume attached on a | +|description | compute blade, a job file as well as parameters are passed | +| | to fio and fio will start doing what the job file tells it | +| | to do. | +| | | ++--------------+--------------------------------------------------------------+ +|configuration | file: opnfv_yardstick_tc006.yaml | +| | | +| | Fio job file is provided to define the benchmark process | +| | Target volume is mounted at /FIO_Test directory | +| | | +| | For SLA, minimum read/write iops is set to 100, | +| | minimum read/write throughput is set to 400 KB/s, | +| | and maximum read/write latency is set to 20000 usec. | +| | | ++--------------+--------------------------------------------------------------+ +|applicability | This test case can be configured with different: | +| | | +| | * Job file; | +| | * Volume mount directory. | +| | | +| | SLA is optional. The SLA in this test case serves as an | +| | example. Considerably higher throughput and lower latency | +| | are expected. However, to cover most configurations, both | +| | baremetal and fully virtualized ones, this value should be | +| | possible to achieve and acceptable for black box testing. | +| | Many heavy IO applications start to suffer badly if the | +| | read/write bandwidths are lower than this. | +| | | ++--------------+--------------------------------------------------------------+ +|usability | This test case is one of Yardstick's generic test. Thus it | +| | is runnable on most of the scenarios. | +| | | ++--------------+--------------------------------------------------------------+ +|references | fio_ | +| | | +| | ETSI-NFV-TST001 | +| | | ++--------------+--------------------------------------------------------------+ +|pre-test | The test case image needs to be installed into Glance | +|conditions | with fio included in it. | +| | | +| | No POD specific requirements have been identified. | +| | | ++--------------+--------------------------------------------------------------+ +|test sequence | description and expected result | +| | | ++--------------+--------------------------------------------------------------+ +|step 1 | A host VM with fio installed is booted. | +| | A 200G volume is attached to the host VM | +| | | ++--------------+--------------------------------------------------------------+ +|step 2 | Yardstick is connected with the host VM by using ssh. | +| | 'job_file.ini' is copyied from Jump Host to the host VM via | +| | the ssh tunnel. The attached volume is formated and mounted. | +| | | ++--------------+--------------------------------------------------------------+ +|step 3 | Fio benchmark is invoked. Simulated IO operations are | +| | started. IOPS, disk read/write bandwidth and latency are | +| | recorded and checked against the SLA. Logs are produced and | +| | stored. | +| | | +| | Result: Logs are stored. | +| | | ++--------------+--------------------------------------------------------------+ +|step 4 | The host VM is deleted. | +| | | ++--------------+--------------------------------------------------------------+ +|test verdict | Fails only if SLA is not passed, or if there is a test case | +| | execution problem. | +| | | ++--------------+--------------------------------------------------------------+ |
