+|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.) |

++--------------+--------------------------------------------------------------+
+|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 host is installed and 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. |
+| | |
