OpenStack control plane performance report

Abstract

This document includes OpenStack control plane performance test results. All tests have been performed regarding openstack_control_plane_performance_test_plan

Environment description

Environment contains 4 types of servers:

• rally node
• controller node
• compute-osd node
• compute node

Amount of servers each role

Role	Servers count
rally	1
controller	3
compute	176
compute-osd	20

Hardware configuration of each server

All servers have same configuration describing in table below

Description of servers hardware

server	vendor,model	HP,DL380 Gen9
CPU	vendor,model ----------------+ processor_count ----------------+ core_count ----------------+ frequency_MHz	Intel,E5-2680 v3 -------------------------------+ 2 -------------------------------+ 12 -------------------------------+ 2500

Network configuration of each server

All servers have same network configuration:

Here is the part of switch configuration for each switch port which connected to ens1f0 interface of a server:

switchport mode trunk
switchport trunk native vlan 600
switchport trunk allowed vlan 600-602,630-649
spanning-tree port type edge trunk
spanning-tree bpduguard enable
no snmp trap link-status

Software configuration on servers with controller, compute and compute-osd roles

Software version on servers with controller, compute and compute-osd roles

Software	Version
OpenStack	Mitaka
Ceph	Hammer
Ubuntu	Ubuntu 14.04.3 LTS

You can find outputs of some commands and /etc folder in the following archives:

controller-1.tar.gz <configs/controller-1.tar.gz>
controller-2.tar.gz <configs/controller-2.tar.gz>
controller-3.tar.gz <configs/controller-3.tar.gz>
compute-1.tar.gz <configs/compute-1.tar.gz>
compute-osd-1.tar.gz <configs/compute-osd-1.tar.gz>

Software configuration on servers with rally role

On this server should be installed Rally. How to do it you can find in Rally installation documentation

Software version on server with rally role

Software	Version
Rally	0.4.0
Ubuntu	Ubuntu 14.04.3 LTS

Testing process

Some test parameters

Name	Value
Volume size to create in Cinder	1GB
Flavor to create VM from	m1.tiny
Image name to create VM from	cirros

1. Create work directory on server with Rally role. In future we will call that directory as WORK_DIR

2. Create directory "plugins" in WORK_DIR and copy to that directory nova_performance.py <../../test_plans/control_plane/plugins/nova_performance.py> plugin.

3. Create directory "scenarios" in WORK_DIR and copy to that directory boot_attach_live_migrate_and_delete_server_with_secgroups.json <rally_scenarios/boot_attach_live_migrate_and_delete_server_with_secgroups.json>, create-and-delete-image.json <rally_scenarios/create-and-delete-image.json> and keystone.json <rally_scenarios/keystone.json> scenarios.

4. Create deployment.json file in WORK_DIR and fill it with OpenStack environment info. It should looks like this:

   configs/deployment.json

5. Create job-params.yaml file in WORK_DIR and fill it with scenarios info. It should looks like this:

   configs/job-params.yaml

6. Perform tests:

   configs/run_test_script.sh

As a result of this part we got the following HTML file:

rally_report.html <configs/rally_report.html>
