+## Running NVMe-OF Performace Testcases
+
+In order to reproduce test cases described in [SPDK NVMe-OF Performance Test Cases](https://ci.spdk.io/download/performance-reports/SPDK_nvmeof_perf_report_18.04.pdf) follow the following instructions.
+
+Currently RDMA NIC IP address assignment must be done manually before running the tests.
+
+# Prepare the configuration file
+
+Configure the target, initiators, and FIO workload in the json configuration file.
+
+## General
+
+Options which apply to both target and all initiator servers such as "password" and "username" fields.
+All servers are required to have the same user credentials for running the test.
+Test results can be found in /tmp/results directory.
+
+### transport
+
+Transport layer to use between Target and Initiator servers - rdma or tcp.
+
+## Target
+
+Configure the target server information.
+
+### nic_ips
+
+List of IP addresses othat will be used in this test..
+NVMe namespaces will be split between provided IP addresses.
+So for example providing 2 IP's with 16 NVMe drives present will result in each IP managing
+8 NVMe subystems.
+
+### mode
+
+"spdk" or "kernel" values allowed.
+
+### use_null_block
+
+Use null block device instead of present NVMe drives. Used for latency measurements as described
+in Test Case 3 of performance report.
+
+### num_cores
+
+List of CPU cores to assign for running SPDK NVMe-OF Target process. Can specify exact core numbers or ranges, eg:
+[0, 1, 10-15].
+
+### nvmet_bin
+
+Path to nvmetcli application executable. If not provided then system-wide package will be used
+by default. Not used if "mode" is set to "spdk".
+
+### num_shared_buffers
+
+Number of shared buffers to use when creating transport layer.
+
+## Initiator
+
+Describes initiator arguments. There can be more than one initiator section in the configuration file.
+For the sake of easier results parsing from multiple initiators please use only digits and letters
+in initiator section name.
+
+### ip
+
+Management IP address used for SSH communication with initiator server.
+
+### nic_ips
+
+List of target IP addresses to which the initiator should try to connect.
+
+### mode
+
+"spdk" or "kernel" values allowed.
+
+### cpus_allowed
+
+List of CPU cores to assign for running SPDK NVMe-OF initiator process.
+Can specify exact core numbers: 0,5
+or ranges: 10-15
+or binding to CPUs 0, 5, and 8 to 15: `cpus_allowed=0,5,8-15`.
+If not specified then will use num_cores option.
+If specified with num_cores then cpu_allowed parameter has higher priority than num_cores.
+
+### num_cores
+
+Applies only to SPDK initiator. Number of CPUs core to use for running FIO job.
+If not specified then by default each connected subsystem gets its own CPU core.
+
+### nvmecli_dir
+
+Path to directory with nvme-cli application. If not provided then system-wide package will be used
+by default. Not used if "mode" is set to "spdk".
+
+### fio_bin
+
+Path to the fio binary that will be used to compile SPDK and run the test.
+If not specified, then the script will use /usr/src/fio/fio as the default.
+
+### extra_params
+
+Space separated string with additional settings for "nvme connect" command
+other than -t, -s, -n and -a.
+
+## fio
+
+Fio job parameters.
+
+- bs: block size
+- qd: io depth - Per connected fio filename target
+- rw: workload mode
+- rwmixread: percentage of reads in readwrite workloads
+- run_time: time (in seconds) to run workload
+- ramp_time: time (in seconds) to run workload before statistics are gathered
+- run_num: how many times to run given workload in loop
+
+# Running Test
+
+Before running the test script use the setup.sh script to bind the devices you want to
+use in the test to the VFIO/UIO driver.
+Run the script on the NVMe-oF target system:
+
+ cd spdk
+ sudo PYTHONPATH=$PYTHONPATH:$PWD/scripts scripts/perf/nvmf/run_nvmf.py
+The script uses the config.json configuration file in the scripts/perf/nvmf directory by default. You can
+specify a different configuration file at runtime as shown below:
+sudo PYTHONPATH=$PYTHONPATH:$PWD/scripts scripts/perf/nvmf/run_nvmf.py /path/to/config file/json config file
+
+The script uses another spdk script (scripts/rpc.py) so we pass the path to rpc.py by setting the Python path
+as a runtime environment parameter.
+
+# Test Results
+
+When the test completes, you will find a csv file (nvmf_results.csv) containing the results in the target node
+directory /tmp/results.
+
+# Processor Counter Monitor (PCM)
+PCM Tools provides a number of command-line utilities for real-time monitoring.
+Before using PCM Tools in nvmf perf scripts it needs to be installed on Target machine.
+PCM source and instructions are available on https://github.com/opcm/pcm.
+To enable PCM in perf test you need to add Target setting in config.json file:
+```
+"pcm_settings": ["pcm_directory", "measure_cpu", "measure_memory", delay_time, measure_interval, sample_count]
+```
+example:
+```
+"pcm_settings": ["/tmp/pcm", true, true, 10, 1, 30]
+```
+Example above will run PCM measure for cpu and memory, with start delay 10s, sample every 1 second,
+and 30 samples for cpu measure. PCM memory do not support sample count.
+
+# Bandwidth monitor (bwm-ng)
+PCM Tools provides a number of command-line utilities for real-time monitoring.
+Before using bwm-ng in nvmf perf scripts it needs to be installed on Target machine.
+To enable bandwidth monitor in perf test you need to add Target setting in config.json file:
+```
+"bandwidth_settings": [bool, sample_count]
+```
+example:
+```
+"bandwidth_settings": [true, 30]
+```
