What are Data Centre networks?

The network’s performance is key to ensuring the seamless operation of your internal business and that your customer’s expectations are met. Data Centre networks connect devices such as servers, storage platforms and security appliances. These networks generally require high throughput rates.

Key features of an efficient Data Centre network:

Performance – The standard connectivity rate is 10Gbps. Although, both 40Gbps and 100Gbps are becoming far more common, with the need to carry larger amounts of traffic east-west between workloads in the Data Centre.

Mobility – Resource mobility is vital when server virtualisation is implemented whether it be a small VMWare vSphere platform or a full private cloud. Virtual server workloads often need to be able to move anywhere within the Data Centre, and potentially even across a WAN to another Data Centre. The network must be able to support this mobility seamlessly and resiliently.

Security – This is paramount in all modern networks, but the security needs for Data Centre networks differs to an office network as it hosts and protects your most precious asset, your data.

Challenges of delivering a Data Centre Network

Technology Selection

The market currently offers a number of solutions, from the classic 3-tier, to spine-and-leaf, and from standards-based solutions such as VXLAN and GENEVE, to proprietary technologies like Cisco ACI or VMWare NSX.

Understanding which technology is right for your current and future needs can be overwhelming and also expensive if the wrong decision is made.


Data Centre Networks must be able to handle a large amount of traffic and support increasing numbers of users, devices, and applications.

The network architecture must be designed with scalability in mind to avoid bottlenecks and performance issues.


The availablity of the Data Centre nertwork is absolutly essential to providing uninterrupted service to the business.

The failure of a single component can lead to downtime, which can lead to lost revenue, decreased productivity, and damaged reputation.


Classic Data Centre network architectures work well, but have certain constraints.

The modern Date Centre must support the mobility requirements of workloads such as virtual application servers, which need to be able to operate not only anywhere within in the Data Centre, but often across physical Data Centre as well.


The data and services located within a Data Centre are likely to be under constant attack and the network is the first line of defence.

Often, the first sign of a security failure is the impact it has on the business, be it unauthorised access, data extraction or ransomware. Getting Data Centre Network security wrong can have a massive impact.


Data Centre Networks are complex, with multiple layers of switches, routers, firewalls, load balancers, and other components.

Designing, implementing, managing and troubleshooting the network can be challenging, and organisations need skilled and experienced IT staff to build, maintain and optimise the network.

Our approach

We have extensive experience designing, building, and supporting Data Centre networks in both SMEs and large-scale enterprises across a number of business sectors.

We will help you by selecting, designing, and implementing the most suitable network solution, ensuring it aligns with your current and future requirements.

We design Data Centre networks that eliminate single points of failure and self-heal if, and when components fail, all while avoiding the high costs associated with over-engineering the design.

We work with you to understand your existing security posture, risks, and threats. This allows us to implement the correct security design, whether it be internet-edge or WAN perimeter security, or macro or micro-segmentation.
