-Storage QPI
-***********
-
-The storage QPI gives user an overall score for storage performance.
-
-The measurement is done by `StorPerf`_.
-

-System Information
-==================
-
-System Information are environmental parameters and factors may affect storage performance:
-
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| System Factors | Detail | Extraction Method |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Ceph Node List | List of nodes which has ceph-osd roles. | Getting from return result of installer node list CLI command. |
-| | For example [node-2, node-3, node-4]. | |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Ceph Client RDB Cache Mode | Values: "None", "write-through", "write-back". | Getting from value of "rbd cache" and "rbd cache max dirty" keys |
-| | | in client section of ceph configuration; To enable write-through mode, |
-| | | set rbd cache max dirty to 0. |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Ceph Client RDB Cache Size | The RBD cache size in bytes. Default is 32 MiB. | Getting from value of "rdb cache size" key in client section |
-| | | of ceph configuration. |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Ceph OSD Tier Cache Mode | Values: "None", "Write-back", "Readonly". | Getting from ceph CLI "ceph report" output info. |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Use SSD Backed OSD Cache | Values: "Yes", "No". | Getting from POD description and CEPH CLI "ceph-disk list" output info. |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Use SSD For Journal | Values: "Yes", "No". | Getting from POD description and CEPH CLI "ceph-disk list" output info. |
-+--------------------------------+-------------------------------------------------+-----------------------------------------------------------------------------+
-| Ceph Cluster Network Bandwidth | Values: "1G", "10G", "40G". | Getting from physical interface information in POD description, |
-| | | "ifconfig" output info on ceph osd node, |
-| | | and value of "cluster network" key in global section of ceph configuration. |

-Test Condition
-==============
-
-+-----------------------------+------------------------------------------+-------------------------------------------------------------+
-| Test Condition | Detail | Extraction Method |
-+-----------------------------+------------------------------------------+-------------------------------------------------------------+
-| Number of Testing VMs | Number of VMs which are created, | It equals the number of Cinder nodes of the SUT. |
-| | during running Storperf test case. | |
-+-----------------------------+------------------------------------------+-------------------------------------------------------------+
-| Distribution of Testing VMS | Number of VMs on each computer node, | Recording the distribution when runing Storperf test case. |
-| | for example [(node-2: 1), (node-3: 2))]. | |
-+-----------------------------+------------------------------------------+-------------------------------------------------------------+
-
-Baseline
-========
-
-Baseline is established by testing with a set of work loads:
-
-- `Queue depth`_ (1, 2, 8)
-- `Block size`_ (2KB, 8KB, 16KB)
-- `Read write`_
- - sequential read
- - sequential write
- - random read
- - random write
- - random mixed read write 70/30
-
-.. _Queue depth: http://fio.readthedocs.io/en/latest/fio_man.html#cmdoption-arg-iodepth
-.. _Block size: http://fio.readthedocs.io/en/latest/fio_man.html#cmdoption-arg-blocksize
-.. _Read write: http://fio.readthedocs.io/en/latest/fio_man.html#cmdoption-arg-readwrite
-
-Metrics
-=======
-
-- Throughput: data transfer rate
-- IOPS: I/O operations per second
-- Latency: response time
-
-Workload Scores
-===============
-
-For each test run, if an equivalent work load in baseline is available, a score will be calculated by comparing the
-result to baseline.
-
-Section Scores
-==============
-
-+-----------------+--------------------------------------------------------+-----------------------------------------+
-| Section | Detail | Indication |
-+=================+========================================================+=========================================+
-| IOPS | Read write I/O Operation per second under steady state | Important for frequent storage access |
-| | Workloads : random read/write | such as event sinks |
-+-----------------+--------------------------------------------------------+-----------------------------------------+
-| Throughput | Read write data transfer rate under steady state | Important for high throughput services |
-| | Workloads: sequential read/write, block size 16KB | such as video server |
-+-----------------+--------------------------------------------------------+-----------------------------------------+
-| Latency | Average response latency under steady state | Important for real time applications |
-| | Workloads: all | |
-+-----------------+--------------------------------------------------------+-----------------------------------------+

-Section score is the `geometric mean <https://en.wikipedia.org/wiki/Geometric_mean>`_ of all
-workload score.
-
-Storage QPI
-===========
-
-Storage QPI is the `weighted arithmetic mean <https://en.wikipedia.org/wiki/Weighted_arithmetic_mean>`_ of all section
-scores.
