Amandeep Singh, Country Manager – Networking, Dell India lists ways to deal with the key disruptors in networking architecture
Today there is a major shift taking place in the networking space that cannot be ignored. An organisation’s network has the potential to transform today’s data centres. Innovative technologies such as SDN, network resource pooling, overlays, east-west traffic and cloud computing have changed how networks have to perform. Factors such as SDN, resource pooling, etc., require new methods of networking from the traditional architectures of the past.
Disruption in technologies has always led to innovation and it’s high time we looked at innovations in networking architecture. And while IT budgets continue to be flat, CIOs being more conscious than ever before, some of the major disruptors in the networking space that have the ability to reduce costs and make networking more efficient for an organisation are as follows:
1. Shift from monolithic chassis switches to active fabric: Previously in the data centre, the conventional networking architecture was followed where monolithic chassis switches prevailed. These typically were expensive to use and maintain and were not scalable. However, over a period of time, the development of spine and leaf architectures using smaller, fixed-form factor switches gained pace. The new switches removes the traditional three tier networking and at the same time offers efficient, economical and scalable solutions. The new form of switches will enable network managers to overcome performance, reliability and scalability differences, compared with chassis-based switches.
2. Intelligent fabric management: Intelligent fabric management software has the potential to bring server-like programming to the network with scripting and other commonly used tools. It has an intuitive interface that guides customers from network design through the wiring plan to finally configure and commission the fabric. It also has the ability to streamline and automate repetitious and time-consuming manual tasks and provides a single-pane of glass to give administrators a bird’s eye view of their entire network.
3.Decoupling control and data planes: It is important to give customers options for how they choose to architect and deploy their data centre networks. Hence making switches OpenFlow – enabled, the very seed of SDN in order to decouple the control plane and data plane elements is not enough. Customers are looking at other options to get similar functionality such as network overlays. Many vendors today support multiple interoperable approaches to SDN which gives customers a wider choice.
