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 on a compute blade, a job | -|description | 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_tc005.yaml | -| | | -| | IO types is set to read, write, randwrite, randread, rw. | -| | IO block size is set to 4KB, 64KB, 1024KB. | -| | fio is run for each IO type and IO block size scheme, | -| | each iteration runs for 30 seconds (10 for ramp time, 20 for | -| | runtime). | -| | | -| | 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: | -| | | -| | * IO types; | -| | * IO block size; | -| | * IO depth; | -| | * ramp time; | -| | * test duration. | -| | | -| | Default values exist. | -| | | -| | 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. | -| | | -+--------------+--------------------------------------------------------------+ -|step 2 | Yardstick is connected with the host VM by using ssh. | -| | 'fio_benchmark' bash script is copyied from Jump Host to | -| | the host VM via the ssh tunnel. | -| | | -+--------------+--------------------------------------------------------------+ -|step 3 | 'fio_benchmark' script 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. | -| | | -+--------------+--------------------------------------------------------------+ |
