Exploring the opportunities and understanding what needs to be considered

Network technology is evolving and over the next few years we'll see Software Defined Networking (SDN) and Network Function Virtualisation (NFV) become far more commonplace. Although the basic technologies have been around for some time, we are only now seeing maturing, standardised products in the marketplace. 

SDN and NFV are quite different technologies but are related by significant common principles. Today, the Wide Area Network (WAN) is a closed and static environment. While improvements have been made in automating capabilities over the years, general management and delivery is still very much a manual process delivered through individual node Command Line Interfaces.

From 2.4GHz to 5GHz: switch with confidence

2.4GHz spectrum is reaching its limits for Wi-Fi networking. But despite the availability of 5GHz, many IT administrators still believe switching is complicated, favouring instead a 50:50 network design.

2.4GHz is the original standard from 1997. It provides just three channels and is now congested, causing interference and dropped connections. According to Gartner, there will be more than 20 billion connected devices by 2020.

If 2.4GHz is to support the ever-increasing volume of connected devices, the industry needs to move beyond a technology developed in the era of the cassette player.

Third-party data centre customer power grew to 713MW in 2016, despite concerns of Brexit and the rising cost of London data centres.

The growth was due in part to the development of facilities outside the capital.

And with more than seven million square foot of data centre space now being taken on by third-party providers, growth beyond the M25 is only set to continue.

Adapting to rapidly changing technology is key to keeping up with – or even outrunning – competition. But sometimes internal staff don’t have the time or skills to manage complex IT infrastructure of office technology, making it necessary to seek out a supplement to your business’ IT department.

Managed service providers (MSPs) specialise in managing key pieces of their clients’ IT infrastructure. The challenge is knowing what to look for when working with an MSP to build an effective field service strategy. As head of nationwide managed service provider ITS, I’ve found the following five tips to be the most helpful:

Modular UPS and block–modular UPS deliver flexibility and efficiency for critical data centre applications

Data centres are a demanding environment for electrical power. They require the highest standards of reliability and availability, but there is constant pressure to reduce power consumption – both for cost reasons, and to reduce the demand on foot print and cooling systems. 

To achieve high availability, it is essential that data centres, as well as smaller server or data rooms, have suitable Uninterruptible Power Supply (UPS) systems in place. These systems are able to ensure secure power in all the cases of a bad quality line, especially in case of mains failure and provide electrical power from back-up batteries long enough to bridge the gap until the mains systems are restored, or power can be provided from a generator or other source, or to allow the secure shut down of critical loads.
