Yardstick Test Case Description TC005ΒΆ

Storage Performance
test case id OPNFV_YARDSTICK_TC005_Storage Performance
metric IOPS, throughput and latency
test purpose To evaluate the IaaS storage performance with regards to IOPS, throughput and latency. The purpose is also to be able to spot trends. Test results, graphs and similar shall be stored for comparison reasons and product evolution understanding between different OPNFV versions and/or configurations.

file: opnfv_yardstick_tc005.yaml

IO types: read, write, randwrite, randread, rw IO block size: 4KB, 64KB, 1024KB, where each runs for 30 seconds(10 for ramp time, 20 for runtime).

For SLA minimum read/write iops is set to 100, minimum read/write throughput is set to 400 KB/s, and maximum read/write latency is set to 20000 usec.

test tool


(fio is not always part of a Linux distribution, hence it needs to be installed. As an example see the /yardstick/tools/ directory for how to generate a Linux image with fio included.)




applicability Test can be configured with different read/write types, IO block size, IO depth, ramp time (runtime required for stable results) and test duration. Default values exist.
pre-test conditions

The test case image needs to be installed into Glance with fio included in it.

No POD specific requirements have been identified.

test sequence description and expected result
step 1

The host is installed and fio is invoked and logs are produced and stored.

Result: Logs are stored.

test verdict Fails only if SLA is not passed, or if there is a test case execution problem.
