+********************************
+Storage Performance Benchmarking
+********************************
+
+Like compute QPI, storage QPI gives users an overall score for system storage performance.
+The project `StorPerf`_ in OPNFV provides a tool to measure ephemeral and block storage
+performance of OpenStack. Naturally, QTIP integrates `StorPerf`_ to generate the storage
+performance data.
+
+For now, storage QPI runs against on the baremetal/virtual scenario deployed by
+the OPNFV installer `APEX`_.
+
+Getting started
+===============
+
+Notice: All descriptions are based on containers.
+
+Requirements
+------------
+
+* Git must be installed.
+* Docker and docker-compose must be installed.
+
+Git Clone QTIP Repo
+-------------------
+
+::
+
+  git clone https://git.opnfv.org/qtip
+
+Running QTIP container and Storperf Containers
+----------------------------------------------
+
+With Docker Compose, we can use a YAML file to configure application's services and
+use a single command to create and start all the services.
+
+There is a YAML file ``./qtip/tests/ci/storage/docker-compose.yaml`` from QTIP repos.
+It can help you to create and start the storage QPI service.
+
+Before running docker-compose, you must specify these three variables:
+
+* DOCKER_TAG, which specified the Docker tag(ie: latest)
+* SSH_CREDENTIALS, a directory which includes an SSH key pair will be mounted into QTIP container.
+  QTIP use this SSH key pair to connect to remote hosts.
+* ENV_FILE, which includes the environment variables required by QTIP and Storperf containers
+
+  A example of ENV_FILE:
+
+  ::
+
+    INSTALLER_TYPE=apex
+    INSTALLER_IP=192.168.122.247
+    TEST_SUITE=storage
+    NODE_NAME=zte-virtual5
+    SCENARIO=generic
+    TESTAPI_URL=
+    OPNFV_RELEASE=euphrates
+    # The below environment variables are Openstack Credentials.
+    OS_USERNAME=admin
+    OS_USER_DOMAIN_NAME=Default
+    OS_PROJECT_DOMAIN_NAME=Default
+    OS_BAREMETAL_API_VERSION=1.29
+    NOVA_VERSION=1.1
+    OS_PROJECT_NAME=admin
+    OS_PASSWORD=ZjmZJmkCvVXf9ry9daxgwmz3s
+    OS_NO_CACHE=True
+    COMPUTE_API_VERSION=1.1
+    no_proxy=,192.168.37.10,192.0.2.5
+    OS_CLOUDNAME=overcloud
+    OS_AUTH_URL=http://192.168.37.10:5000/v3
+    IRONIC_API_VERSION=1.29
+    OS_IDENTITY_API_VERSION=3
+    OS_AUTH_TYPE=password
+
+Then, you use the following commands to start storage QPI service.
+
+::
+
+  docker-compose -f docker-compose.yaml pull
+  docker-compose -f docker-compose.yaml up -d
+
+Execution
+---------
+
+You can run storage QPI with docker exec:
+::
+
+  docker exec <qtip container> bash -x /home/opnfv/repos/qtip/qtip/scripts/quickstart.sh
+
+QTIP generates results in the ``$PWD/results/`` directory are listed down under the
+timestamp name.
+
+Metrics
+-------
+
+Storperf provides the following `metrics`_:
+
+* IOPS
+* Bandwidth (number of kilobytes read or written per second)
+* Latency
