+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))]. | |
