3 Upgrading the controller from version 2.3 to version 2.4

This chapter upgrades the controller from an existing version 2.3 installation to version 2.4.

NOTE: This procedure assumes:

You have already downloaded the controller software package as described under “Downloading the controller software” (page 7).

The provider type was set to UUID when controller version 2.3 was installed on your machine.

Network Time Protocol (NTP) is already installed and configured on your system.

Where a command in this procedure is shown with multiple lines, the line breaks are inserted at the points where a space occurs in the actual command.

To install the downloaded HP VAN SDN Controller software:

1.Ensure that you have root access on the Ubuntu system (sudo).

2.Unpack the HP VAN SDN Controller from the directory in which the package is stored:

NOTE: In the following command, two hyphens precede the unpack keyword; that is, --unpack.

~$ sudo dpkg -–unpack hp-sdn-ctl_2.4.x.yyyy_amd64.deb (Where x.yyyy completes the actual release version number of the controller. For example, 2.4.3.0595.)

3.Execute the following command to install software dependencies.

~$ sudo apt-get install -f

If you are prompted with Do you want to continue [Y/n]?, type Y and press Enter.

4.In the command line window, verify that the sdnc service is started:

~$ sudo service sdnc status

Wait 60 seconds for the sdnc service process to complete. If the service fails to start, see “Troubleshooting” (page 21).

You should see the following output, which indicates that the sdnc service is started:

~$ sdnc start/running, process nnnn

Where: nnnn is the process ID assigned to the main HP VAN SDN Controller process (sdnc).

5.Go to “Operating the HP VAN SDN Controller” (page 17).

VAN SDN Controller Software Products specifications

HP VAN SDN Controller Software Products represent a significant advancement in network management by leveraging software-defined networking (SDN) principles. These products aim to centralize control of network resources, provide enhanced automation, and simplify network management, which can dramatically improve the overall performance and agility of data centers.

One of the main features of HP VAN SDN Controller is its ability to enable an application-centric network environment. By separating the control plane from the data plane, network administrators can gain a holistic view of the entire network. This separation allows for dynamic reconfiguration of network devices and sets the stage for the development of innovative applications that can respond to real-time network conditions.

The controller supports OpenFlow as its primary protocol, ensuring interoperability with a wide range of network devices from different vendors. This compatibility facilitates a heterogeneous network environment, allowing organizations to transition to SDN at their own pace without needing to replace all existing hardware. It also promotes vendor diversity, reducing the risk of vendor lock-in.

HP VAN SDN Controller features robust security capabilities, including support for micro-segmentation, which helps in isolating critical components within the network. This layer of security can safeguard sensitive data and protect against threats, ensuring that only authorized traffic is allowed within designated network segments.

Another key characteristic is the controller's emphasis on automation and orchestration. Through APIs and built-in tools, network policies can be defined and applied consistently across the entire network. This intelligent automation reduces the potential for human error and accelerates the implementation of networking changes, enabling organizations to adapt quickly to evolving business needs.

The HP VAN SDN Controller also incorporates advanced analytics capabilities that provide real-time visibility into network performance. These analytics can help in troubleshooting, forecasting capacity needs, and optimizing resource utilization, contributing to improved operational efficiency and reduced downtime.

Furthermore, the scalable architecture of the HP VAN SDN Controller makes it suitable for various environments, from small enterprises to large-scale data centers. The product supports multi-tenancy, allowing multiple virtual networks to coexist on the same infrastructure, which can be ideal for service providers and organizations operating within cloud environments.

In summary, HP VAN SDN Controller Software Products deliver a powerful suite of features and technologies that enhance network control, security, automation, and scalability, positioning organizations to leverage the full potential of software-defined networking.
