+|Storage Performance |

++--------------+--------------------------------------------------------------+
+|test case id | OPNFV_YARDSTICK_TC079_Bonnie++ |
+| | |
++--------------+--------------------------------------------------------------+
+|metric | Sequential Input/Output and Sequential/Random Create speed |
+| | and CPU useage. |
+| | |
++--------------+--------------------------------------------------------------+
+|test purpose | The purpose of TC078 is to evaluate the IaaS storage |
+| | performance with regards to Sequential Input/Output and |
+| | Sequential/Random Create speed and CPU useage statistics. |
+| | |
++--------------+--------------------------------------------------------------+
+|test tool | Bonnie++ |
+| | |
+| | Bonnie++ is a disk and file system benchmarking tool for |
+| | measuring I/O performance. With Bonnie++ you can quickly and |
+| | easily produce a meaningful value to represent your current |
+| | file system performance. |
+| | |
+| | Bonnie++ is not always part of a Linux distribution, hence |
+| | it needs to be installed in the test image. |
+| | |
++--------------+--------------------------------------------------------------+
+|test | This test case uses Bonnie++ to perform the tests below: |
+|description | * Create files in sequential order |
+| | * Stat files in sequential order |
+| | * Delete files in sequential order |
+| | * Create files in random order |
+| | * Stat files in random order |
+| | * Delete files in random order |
+| | |
++--------------+--------------------------------------------------------------+
+|configuration | file: bonnie++.yaml (in the 'samples' directory) |
+| | |
+| | file_size is set to 1024; ram_size is set to 512; |
+| | test_dir is set to '/tmp'; concurrency is set to 1. |
+| | |
+| | SLA is not available in this test case. |
+| | |
++--------------+--------------------------------------------------------------+
+|applicability | Test can be configured with different: |
+| | |
+| | * file_size - size fo the test file in MB. File size should |
+| | be double RAM for good results; |
+| | * ram_size - specify RAM size in MB to use, this is used to |
+| | reduce testing time; |
+| | * test_dir - this directory is where bonnie++ will create |
+| | the benchmark operations; |
+| | * test_user - the user who should perform the test. This is |
+| | not required if you are not running as root; |
+| | * concurrency - number of thread to perform test; |
+| | |
++--------------+--------------------------------------------------------------+
+|usability | This test case is used for executing Bonnie++ benchmark in |
+| | VMs. |

+|pre-test | The Bonnie++ distribution includes a 'bon_csv2html' Perl |
+|conditions | script, which takes the comma-separated values reported by |
+| | Bonnie++ and generates an HTML page displaying them. |
+| | To use this feature, bonnie++ is required to be install with |
+| | yardstick (e.g. in yardstick docker). |
+| | |
++--------------+--------------------------------------------------------------+
+|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. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 3 | Bonnie++ benchmark is invoked. Simulated IO operations are |
+| | started. Logs are produced and stored. |
+| | |
+| | Result: Logs are stored. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 4 | An HTML report is generated using bonnie++ benchmark results |
+| | and stored under /tmp/bonnie.html. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 5 | The host VM is deleted. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | None. Bonnie++ html report is generated. |
