About This Guide

The scope of this manual is to describe the installation process for HP Distributed Cloud Networking (DCN).

Audience

This manual is intended for system administrators who are responsible for installing and configuring the HP DCN software.

1 HP DCN: Overview and Infrastructure

This chapter provides an overview of HP Distributed Cloud Networking (DCN) 3.0.R2 and of the infrastructure required to implement the DCN solution. It also gives a brief overview of the installation process itself.

Topics in this chapter include:

• HP DCN Overview

• HP DCN Infrastructure Requirements and Recommendations

• Data Center IP Network

• NTP Infrastructure

• Domain Name System

• Certificate Authority

• HP DCN Installation Overview

HP DCN Overview

HP DCN is a Software-Defined Networking (SDN) solution that enhances data center (DC) network virtualization by automatically establishing connectivity between compute resources upon their creation. Leveraging programmable business logic and a powerful policy engine, HP DCN provides an open and highly responsive solution that scales to meet the stringent needs of massive multi-tenant DCs. HP DCN is a software solution that can be deployed over an existing DC IP network fabric. Figure 1 illustrates the logical architecture of the HP DCN solution.

Figure1:HPDCNArchitectureandComponents

HP DCN Overview 7

There are three main components in the HP DCN solution: HP Virtualized Services Directory (HP VSD), HP Virtualized Services Controller (HP VSC) and HP Virtual Routing and Switching (HP VRS).

HP Virtualized Services Directory

HP VSD is a programmable policy and analytics engine that provides a flexible and hierarchical network policy framework that enables IT administrators to define and enforce resource policies.

HP VSD contains a multi-tenant service directory which supports role-based administration of users, computers, and network resources. It also manages network resource assignments such as IP and MAC addresses.

HP VSD enables the definition of sophisticated statistics rules such as:

• collection frequencies

• rolling averages and samples

• threshold crossing alerts (TCAs).

When a TCA occurs it will trigger an event that can be exported to external systems through a generic messaging bus.

Statistics are aggregated over hours, days and months and stored in a Hadoop® analytics cluster to facilitate data mining and performance reporting.

HP VSD is composed of many components and modules, but all required components can run on a single Linux server or in a single Linux virtual machine. Redundancy requires multiple servers or VMs.

To get a license key to activate your HP VSD, contact your HP Sales Representative.

HP Virtualized Services Controller

HP VSC functions as the robust network control plane for DCs, maintaining a full view of pertenant network and service topologies. Through the HP VSC, virtual routing and switching constructs are established to program the network forwarding plane, HP VRS, using the OpenFlow™ protocol.

The HP VSC communicates with the VSD policy engine using Extensible Messaging and Presence Protocol (XMPP). An ejabberd XMPP server/cluster is used to distribute messages between the HP VSD and HP VSC entities.

Multiple HP VSC instances can be federated within and across DCs by leveraging MP-BGP.

The HP VSC is based on HP DCN Operating System (DCNOS) and runs in a virtual machine environment.

HP Virtual Routing and Switching

HP VRS is an enhanced Open vSwitch (OVS) implementation that constitutes the network forwarding plane. It encapsulates and de-encapsulates user traffic, enforcing L2-L4 traffic policies as defined by the HP VSD. The HP VRS tracks VM creation, migration and deletion events in order to dynamically adjust network connectivity.

8 HP DCN: Overview and Infrastructure

HP VRS-G

For low volume deployments the software based HP VRS Gateway (VRS-G) module incorporates bare metal as virtualized extensions to the datacenter.

HP DCN Infrastructure Requirements and Recommendations

In order to make use of the HP DCN, the data center environment must meet some key requirements as described in the following sections.

Data Center IP Network

HP VSP can be used in any data center with an IP network. HP VSC actively participates in the IP routing infrastructure. HP VSCs can run OSPF or IS-IS for the IGP in addition to BGP, but integration with the IGP is not mandatory.

BGP is used to form a federation of HP VSCs and synchronize the HP VSP network information. In addition, BGP is also used to exchange routing information with the data center provider edge router.

NTP Infrastructure

Because HP VSP is a distributed system, it is important that the different elements have a reliable reference clock to ensure the messages exchanged between the elements have meaningful timestamps. HP VSP relies on each of the elements having clocks synchronized with NTP.

The HP VSD and HP VRS applications rely on the NTP facilities provided by the host operating system. The HP VSC, which is based on HP DCN OS, has an NTP client.

HP recommends having at least three NTP reference clocks configured for each system.

Domain Name System

In scaled HP VSP deployments, the HP VSD functional elements can be distributed across machines into clusters of machines where the failover and load sharing mechanisms for the clusters rely on being referenced as a single DNS entity.

Certificate Authority

The northbound ReST API on HP VSD is accessed within an SSL session. The HP VSD is able to use a self-signed certificate, but having a certificate from a certificate authority will enable client applications to avoid processing security warnings about unrecognized certificate authorities.

HP DCN Installation Overview

Installing HP DCN consists of installing the three software components (HP VSD, HP VSC, and HP VRS) and configuring their interfaces to establish connectivity between them.

HP DCN Infrastructure Requirements and Recommendations 9

Figure2:InstallationSetup

Figure 2 diagrams the installation of the HP VSP components and shows how they

communicate with each other. The labeled interfaces are referenced in the installation instructions. The diagram could be used to map out the topology you plan to use for your own installation.

The recommended order for installing the software is the order presented in this guide because each newly installed software item component provides the infrastructure to communicate with the next component on the list.

After installing HP DCN, configure policies in the HP VSD to derive full benefit from the system.

• HP VSD Installation Using QCow2 Image

• HP VSD Installation Using ISO Disc Image

• Import Certificates on the Servers

• Example of Load Balancer Configuration

HP VSD Hardware and Software Requirements

Installing HP VSD software requires:

• A hypervisor of the specifications set out in the Release Notes

• A mechanism to access the graphical console of the HP VSD appliance (e.g. VNC)

• IP address for the HP VSD appliance(s) and host name(s) defined in DNS and accessible to

all VSP components.

For a license key to activate HP VSD once installed, contact your HP Sales Representative.

HP VSD Installation Overview

The procedures set out here assume installation on a hypervisor running KVM.

Installation Types

There are two types of installation, standalone and high availability.

High Availability

HP VSD High Availability is intended to guard against single-failure scenarios. High availability for HP VSD is implemented as a 3 + 1 node cluster as shown in Figure 3.

For high availability of the HP VSD nodes, it is necessary to ensure each VSD node has redundant network and power, so that no single failure can cause loss of connectivity to more than one HP VSD node. Therefore, each HP VSD node should be installed on a different hypervisor.

EachHPVSDinstanceandNameNoderequiresanindividualnetworkinterface.Allnodesmust beIP‐reachable.

HP VSD Hardware and Software Requirements 11

Figure3:HPVSD3+1HACluster

The cluster consists of three HP VSD nodes and one statistics master node (Name node). In addition, a Load Balancer (not supplied) is optional to load balance across the HP VSD nodes for the REST API.

Installation Methods

The standard method of installation of HP VSD uses the pre-installed appliance. This appliance is distributed in four formats.

• a ready-to-use QCow2 VM image for KVM hypervisor deployment (see HP VSD Installation

Using QCow2 Image

)

• a ready-to-use image for VMWare hypervisor deployment

• a ready-to-use image for OVA hypervisor deployment

• an ISO disc image (see HP VSD Installation Using ISO Disc Image)

Table 1 provides an overview of the installation tasks with links to each.

Notes on Reinstallation: MySQL Root Password

The password for the MySQL root user is not set after installation, because the HP VSD installation scripts require that the root user not have a MySQL password.

Reinstalling HP VSD

To reinstall HP VSD, before uninstalling:

1. Set the root password to ‘no password.’ On each node, run:

mysql -uroot -p<current password> -e “update mysql.user set password=PASSWORD(‘’) where user=’root’; flush privileges;”

2. Uninstall all HP VSD nodes.

3. Install all HP VSD nodes following the procedure specified for your HP VSD version and installation type.

4. Verify that installation was successful.

5. Set the root password:

To set the root password for the first time, on each node, run:

12 HP DCN Software Installation

mysql -e “update mysql.user set password=PASSWORD <NEW PASSWORD> WHERE USER=’ROOT’; FLUSH PRIVILEGES;”

To change the root password, on each node, run:

mysql -uroot -p<current password> -e “update mysql.user set password=PASSWORD <new password> where user =’root’; flush privileges;”

Set Up Appliance VMs

1. Unzip all the HP VSD tar files to a temporary location.

2. If you do not already have virt-install on your hypervisor(s), run this command to put it in:

yum install virt-install

3. Copy the HP VSD qcow2 image to the KVM hypervisor image location <TTY>/var/lib/

libvirt/images/ on each hypervisor.

4. Create appliance VMs.

In the example below, a VM is created for each of four HP VSD nodes. If you are doing a standalone installation, create only

myh1.

Note: “listen=0.0.0.0” results in KVM responding to VNC connection requests on all IP

interfaces. Depending on your network configuration, this may be a security issue.

HP VSD Installation Using QCow2 Image 13

Consider removing “listen=0.0.0.0” and using an alternative method (for example,

hypervisor1server# vsd_name=myh1 hypervisor1server# vsd_disk=/var/lib/libvirt/images/myh1.qcow2 hypervisor1server# virt-install --connect qemu:///system -n $vsd_name -r 24576 --os-type=linux --os-variant=rhel6 --disk path=$vsd_disk,device=disk,bus=virtio,format=qcow2 --vcpus=6 -graphics vnc,listen=0.0.0.0 --noautoconsole --import

• Connect Via VNC)

• Connect Via virsh Console).

Connect Via VNC

Using a VNC client (e.g. RealVNC, TightVNC) or other console access mechanism, connect to the HP VSD appliance consoles and log in using the default username and password:

Connect Via virsh Console

Using a virsh console domain command, connect to the HP VSD appliance consoles and log in using the default username and password.

Configure Networking

1. Do not use DHCP. Use static IP instead. To do this, modify the file

/etc/sysconfig/network-scripts/ifcfg-eth0 to use your static IP and gateway,

replacing BOOTPROTO value “

BOOTPROTO="static" IPADDR=192.168.10.101 GATEWAY=192.168.100.1 NETMASK=255.255.255.0

2. Restart networking on the guest:

3. Ping the gateway (in this example, 192.168.100.1).

/etc/init.d/network restart

4. Ping the gateway (in this example, 192.168.100.1).

ping 192.168.100.1

Configure DNS Server

dhcp” with “static”.

Set up the fully qualified names for all the nodes in the cluster (unless you are doing a standalone installation, in which case one FQDN is obviously sufficient). Reverse DNS lookup for the HP VSD nodes should also be set up.

Note: If the Service Records (SRV) for the XMPP cluster are not in the Domain Name

Server (DNS), the script will generate them. An administrator must then load them into the DNS server. The XMPP cluster name is typically xmpp host in the domain,

HP VSD Installation Using QCow2 Image 15

for example, xmpp.example.com. To use a different host name run the install.sh with the -x option.

TheDNSserverinthisexampleis10.10.10.100.

Test DNSandreverseDNSfromeachVSDnode(VM).

1. Set up the fully qualified names for the nodes in the DNS server forward named file as per the following example:

myh1.myd.example.com. 604800 IN A 192.168.10.101 myh2.myd.example.com. 604800 IN A 192.168.10.102 myh3.myd.example.com. 604800 IN A 192.168.10.103 myname.myd.example.com. 604800 IN A 192.168.10.104

The installation script verifies the DNS forward named file records.

2. From the HP VSD node, verify the SRV record as follows:

server# dig +noall +an @10.10.10.100 SRV _xmpp-client._tcp.xmpp.example.com _xmpp-client._tcp.xmpp.example.com. 604800 IN SRV 10 0 5222 myh1.myd.example.com. _xmpp-client._tcp.xmpp.example.com. 604800 IN SRV 10 0 5222 myh2.myd.example.com. _xmpp-client._tcp.xmpp.example.com. 604800 IN SRV 10 0 5222 myh3.myd.example.com. _xmpp-client._tcp.xmpp.example.com. 604800 IN SRV 10 0 5222 myname.myd.example.com.

3. Set up the fully qualified names for the nodes in the DNS server reverse named file as per the following example:

vsd# dig +noall +an @10.10.10.100 -x 192.168.10.101 vsd# dig +noall +an @10.10.10.100 -x 192.168.10.102 vsd# dig +noall +an @10.10.10.100 -x 192.168.10.103 vsd# dig +noall +an @10.10.10.100 -x 192.168.10.104

4. Verify the DNS reverse named file records as follows:

101.10.168.192.in-addr.arpa. 604800 IN PTR myh1.myd.example.com.

102.10.168.192.in-addr.arpa. 604800 IN PTR myh2.myd.example.com.

103.10.168.192.in-addr.arpa. 604800 IN PTR myh3.myd.example.com.

104.10.168.192.in-addr.arpa. 604800 IN PTR myname.myd.example.com.

5. Set up forward DNS records as follows:

; hosts myh1 A 192.168.10.101 myh2 A 192.168.10.102 myh3 A 192.168.10.103 myname A 192.168.10.104 ; xmpp nodes xmpp A 192.168.10.101 xmpp A 192.168.10.102 xmpp A 192.168.10.103 ; SRV records for xmpp.example.com _xmpp-client._tcp.xmpp.example.com. IN SRV 10 0 5222 myh1.myd.example.com. _xmpp-client._tcp.xmpp.example.com. IN SRV 10 0 5222 myh2.myd.example.com. _xmpp-client._tcp.xmpp.example.com. IN SRV 10 0 5222 myh3.myd.example.com.

Configure NTP Server

Include one or more NTP servers in the /etc/ntp.conf file. For example, edit the NTP file and add servers as follows, restarting the NTPD service to put these parameters into effect:

server 10.10.0.10 server 192.16.10.10 server 192.16.20.10

Install HP VSD using qcow2

The install script is interactive. Node 1 is the master node, and it serves as a template for the other nodes.

Note: HP VSD consists of several components and providing high availability for each of

these components can be quite complex. It is imperative that the installation and powering-on of each node be done in the order specified here.

1. Install HP VSD on Node 1.

The install script checks for the XMPP proxy entry in your DNS. Run

install.sh -x xmpp.myd.example.com

[root@myh1 ~]# <TTY>/opt/vsd/install.sh -x xmpp.myd.example.com

----------------------------------------------------VSD supports two configurations:

1) HA, consisting of 2 redundant installs of VSD with an optional statistics server.

2) Standalone, where all services are installed on a single machine. Is this a redundant (r) or standalone (s) installation [r|s]? (default=s): Is this install the first (1), second (2), third (3) or cluster name node (t) [1|2|3|t]: 1 Please enter the fully qualified domain name (fqdn) for this node:

, substituting your own XMPP server name.

HP VSD Installation Using ISO Disc Image

Note: Consult the Release Notes for the ISO installation requirements.

The following instructions are for a High Availability installation. For a standalone installation, use the same instructions to install one HP VSD on a single node.

Set Up VM for ISO

2. Extract and Mount ISO Image

3. Configure Networking

4. Configure DNS Server

5. Configure NTP Server

6. Install HP VSD Using ISO

Set Up VM for ISO

Note: “listen=0.0.0.0” results in KVM responding to VNC connection requests on

all IP interfaces. Depending on your network configuration, this may be a security issue. Consider removing “listen=0.0.0.0” and using an alternative method (for example,

18 HP DCN Software Installation

virt-manager or SSH tunnel) to obtain console access.

1. Bring up a VM named myh1 using 24 GB RAM and 6 logical cores with the following commands:

# vsd_name=myh1 # vsd_disk=<TTY>/var/lib/libvirt/images/[xxx].qcow2 # virt-install --connect qemu:///system -n $vsd_name -r 24576 --os-type=linux \

--os-variant=rhel6 \

--disk path=$vsd_disk,device=disk,bus=virtio,format=qcow2 \

--vcpus=6 --graphics vnc,listen=0.0.0.0 --noautoconsole --import

2. Repeat this step for each additional hypervisor, naming the additional vsd instances myh2, myh3, and myname.

Extract and Mount ISO Image

1. Extract the ISO disc image from the tar file to a temporary location.

2. Mount the ISO disc image from the temporary location to <TTY>/media/CDROM/ on each node.

Note: Ensure that the ISO is mounted to the same location on each node.

Configure Networking, DNS, and NTP

1. See Configure Networking.

2. See Configure DNS Server.

3. See Configure NTP Server.

Install HP VSD Using ISO

1. Install VSD on Node 1.

The install script checks for the XMPP proxy entry in your DNS. Run /media/CDROM/install.sh

-x xmpp.myd.example.com

[root@myh1 ~]# /media/CDROM/install.sh -x xmpp.myd.example.com

----------------------------------------------------VSD supports two configurations:

1) HA, consisting of 2 redundant installs of VSD with an optional statistics server.

2) Standalone, where all services are installed on a single machine. Is this a redundant (r) or standalone (s) installation [r|s]? (default=s): Is this install the first (1), second (2), third (3) or cluster name node (t) [1|2|3|t]: Please enter the fully qualified domain name (fqdn) for this node:

myh1.myd.example.com

Install VSD on the 1st HA node myh1.myd.example.com ... What is the fully qualified domain name for the 2nd node of VSD:

myh2.myd.example.com

What is the fully qualified domain name for the 3rd node of VSD:

myh3.myd.example.com

What is the fully qualified domain name for the cluster name node of VSD:

myname.myd.example.com

What is the fully qualified domain name for the load balancer (if any)

, substituting your own XMPP server name.

(default=none): Node 1: myh1.myd.example.com Node 2: myh2.myd.example.com Node 3: myh3.myd.example.com Name Node: myname.myd.example.com XMPP: xmpp.myd.example.com Continue [y|n]? (default=y): Starting VSD installation. This may take as long as 20 minutes in some situations ... A self-signed certificate has been generated to get you started using VSD. You may import one from a certificate authority later. VSD installed on this host and the services have started. Please install VSD on myh2.myd.example.com to complete the installation.

2. Install HP VSD on Node 2:

[root@myh2 ~]# /media/CDROM/install.sh

----------------------------------------------------VSD supports two configurations:

1) HA, consisting of 3 redundant installs of VSD with a cluster name node server.

2) Standalone, where all services are installed on a single machine. Is this a redundant (r) or standalone (s) installation [r|s]? (default=s): Is this install the first (1), second (2), third (3) or cluster name node (t) [1|2|3|t]: Please enter the fully qualified domain name for the 1st node of VSD:

myh1.myd.example.com

3. Follow the interactive script to install VSD on Node 3.

4. Follow the interactive script to install VSD on the Name Node.

5. Verify that your VSD(s) are up and running by using the following command:

service vsd status

Import Certificates on the Servers

On each HP VSD host, installation generates a self-signed certificate. If you want to import an official certificate signed by a certificate authority, use the

• Import a certificate generated by a Certificate Authority:

# ./set-cert.sh -r -i certificateFilename

• Generate and use a self-signed certificate if you do not run a proxy:

# ./set-cert.sh -r

20 HP DCN Software Installation

set-cert.sh script:

• Generate and use a self-signed certificate if you run a proxy:

# ./set-cert.sh -r -p proxyHostname

Select an option and generate or import the certificate to Node 1. If you are running HA VSD, import it to Nodes 2 and 3 as well.
