Network scheme of the environment:

Here is the part of switch configuration for each switch port which connected to p1p1 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

3.1.3. Software configuration of the Nexus service¶

3.1.3.1. Installation of Nexus:¶

# Install Java
apt-get install software-properties-common
sudo add-apt-repository ppa:webupd8team/java
apt-get update
sudo apt-get install oracle-java8-installer # Interactive java installer
# Install Nexus
wget http://download.sonatype.com/nexus/3/nexus-3.0.0-m7-unix.sh
chmod +x nexus-3.0.0-m7-unix.sh
echo "o
1

n
y

1

" | ./nexus-3.0.0-m7-unix.sh -c
service nexus restart
update-rc.d nexus defaults

After installation all default repositories was removed from Nexus and “docker-local” hosted repository was created. You can find full configuration of the Nexus installation in the support file created after configuration: support.zip

Versions of some software¶
Software	Version
Ubuntu	Ubuntu 14.04.3 LTS
NexusOSS	3m7

3.1.3.2. Operating system configuration:¶

You can find outputs of some commands and /etc folder in the following archive: server_description_of_728998-comp-disk-227.tar.gz

3.1.4. Software configuration of the node with test tool¶

3.1.4.1. Test tool:¶

Firstly we need to install docker-engine:

echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" > /etc/apt/sources.list.d/docker.list
apt-get update && apt-get -y install docker-engine
echo DOCKER_OPTS=\"--insecure-registry 172.20.9.16:5000\" >> /etc/default/docker
service docker restart

We use Python2.7 and Script for collecting performance metrics with Proposed docker file to perform the tests. The image size is a sum of layers:

It means that DATA_SIZE=206.13 MB

Versions of some software¶
Software	Version
Ubuntu	Ubuntu 14.04.3 LTS
Docker	1.10

3.1.4.2. Operating system:¶

You can find outputs of some commands and /etc folder in the following archive: server_description_of_728997-comp-disk-228.tar.gz

3.2. Testing process¶

Nexus was installed on top of 728998-comp-disk-227 server as described in Installation of Nexus: section.
The values of the variables in test-repo.py script was changed: iterations = 1000 concurrency = 1 repo_address = “172.20.9.16:5000”

The following command was executed to perform the tests:

sudo docker login -u jenkins -p jenkins -e jenkins@example.com
sudo python test-repo.py

push_results.csv and pull_results.csv was saved in persistent folder.
The steps from 1 to 4 was repeated with the following values of the concurrency parameters: 1,10,30,50,100

As a result of this part we got the following CSV files:

PUSH_TIME(CONCURRENCY=1) PUSH_TIME(CONCURRENCY=10) PUSH_TIME(CONCURRENCY=30) PUSH_TIME(CONCURRENCY=50) PUSH_TIME(CONCURRENCY=100) PULL_TIME(CONCURRENCY=1) PULL_TIME(CONCURRENCY=10) PULL_TIME(CONCURRENCY=30) PULL_TIME(CONCURRENCY=50) PULL_TIME(CONCURRENCY=100)

3.3. Results¶

3.3.1. Push action results¶

3.3.1.1. PUSH_TIME(ITERATION)¶

After simple processing results the following plots for push action in depend on iteration number created (click to expand an image):

Function	Plot
PUSH_TIME (ITERATION, CONCURRENCY=1)
PUSH_TIME (ITERATION, CONCURRENCY=10)
PUSH_TIME (ITERATION, CONCURRENCY=30)
PUSH_TIME (ITERATION, CONCURRENCY=50)
PUSH_TIME (ITERATION, CONCURRENCY=100)
PUSH_TIME (ITERATION, CONCURRENCY={1, 10,30,50,100}	$PUSH_TIME(ITERATION, CONCURRENCY={1,10,30,50,100}$

3.3.1.2. PUSH_TIME(CONCURRENCY)¶

The following table and graph show how PUSH_TIME parameter depend on CONCURRENCY parameter.

Maximum, Minimum, Average and Percentile 90% of PUSH_TIME values in depend on CONCURRENCY parameter.¶
Concurrency	Maximum	Minimum	Average	Percentile 90%
1	19.54624987	18.28802991	18.60292332	18.85230837
