6.3. Results of OpenStack Services density testing¶

Abstract: This document includes density test results of OpenStack services. All tests have been performed regarding OpenStack control plane density testing

6.3.1. Environment description¶

Environment contains 5 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

6.3.1.1. Hardware configuration of each server¶

All servers have same configuration describing in table below

6.3.1.2. Network configuration of each server¶

All servers have the similar network configuration:

Here is a part of switch configuration for each switch port which is 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

6.3.1.3. Software configuration on servers with controller and compute roles¶

Services on servers by role¶
Role	Service name
controller	horizon keystone nova-api nava-scheduler nova-cert nova-conductor nova-consoleauth nova-consoleproxy cinder-api cinder-backup cinder-scheduler cinder-volume glance-api glance-glare glance-registry neutron-dhcp-agent neutron-l3-agent neutron-metadata-agent neutron-openvswitch-agent neutron-server heat-api heat-api-cfn heat-api-cloudwatch ceph-mon rados-gw heat-engine
compute	nova-compute neutron-l3-agent neutron-metadata-agent neutron-openvswitch-agent

Software version on servers with controller and compute 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 controller-2.tar.gz controller-3.tar.gz compute-1.tar.gz compute-osd-1.tar.gz

6.3.1.4. Software configuration on servers with Rally role¶

Rally should be installed manually on this server. The extended instructions can be found in Rally installation documentation

Software version on server with Rally role¶
Software	Version
Rally	0.4.0
Ubuntu	Ubuntu 14.04.3 LTS

6.3.2. Test results¶

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