|Storage Performance |
| |
+--------------+--------------------------------------------------------------+
|test case id | OPNFV_YARDSTICK_TC005_Storage Performance |
| | |
+--------------+--------------------------------------------------------------+
|metric | IOPS, throughput and latency |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To evaluate the IaaS storage performance with regards to |
| | IOPS, throughput and latency. |
| | The purpose is also to be able to spot trends. Test results, |
| | graphs and similar shall be stored for comparison reasons |
| | and product evolution understanding between different OPNFV |
| | versions and/or configurations. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: opnfv_yardstick_tc005.yaml |
| | |
| | IO types: read, write, randwrite, randread, rw |
| | IO block size: 4KB, 64KB, 1024KB, where each |
| | 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. |
| | |
+--------------+--------------------------------------------------------------+
|test tool | fio |
| | |
| | (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.) |
| | |
+--------------+--------------------------------------------------------------+

| | |
| | ETSI-NFV-TST001 |
| | |
+--------------+--------------------------------------------------------------+
|applicability | Test can be configured with different read/write types, IO |
| | block size, IO depth, ramp time (runtime required for stable |
| | results) and test duration. Default values exist. |
| | |
+--------------+--------------------------------------------------------------+
|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 | The hosts are installed, as server and client. fio is |
| | invoked and logs are produced and stored. |
| | |
| | Result: Logs are stored. |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | Fails only if SLA is not passed, or if there is a test case |
| | execution problem. |
| | |
