In the era of virtualisation and cloud computing, enterprise cloud spending is expected to grow at a 16% compound annual growth rate (CAGR) between now and 2026 (source: Wikibon).

This rapid growth will have a major impact on how we design our server rooms, with scalability becoming vital. In fact it will be essential for a server room to be able to adapt to constantly changing requirements dictated by the growth in volumes of data.

Conversely, virtualisation and cloud computing will have less and less impact on the physical sizing of server rooms. But this temporary phenomenon will be followed by a significant increase which will then necessitate the physical expansion of server rooms. The massive growth in data volumes forecast over the coming years will contribute to this considerably.


Required flexibility of the server room

The temporary physical reduction in the size of server rooms will lead to increased energy density due to the use of servers with medium and high density power requirements. Due to changing needs in terms of numbers of racks and power and the fluctuations that this involves in terms of cooling, it is essential for the design of server rooms to be flexible and scalable.


A modular approach

It must therefore be possible for the capacity of a modern server room to be increased or decreased quickly and easily. It is therefore clear that the building of server rooms requires a modular approach in order to provide an optimum response to current and future needs and to changes in the market.

A modular approach to building a server room involves a great deal more than simply making it easy to add or remove racks: modularity also applies to energy distribution, the backup power supply, cooling the network, etc. This makes it necessary to constantly adapt the consumption of the server room to the needs of the computer installation.


The Legrand advantage

All the Legrand Group’s data center solutions are designed on the principles of scalability and flexibility.


The aim: a modular data center able to respond to future needs.

Legrand has therefore developed dedicated solutions for you, providing an infrastructure that is scalable at all levels: from energy distribution to data hosting, and including cooling solutions.

These solutions allow you to anticipate needs, so as to make future upgrades possible, and to increase the capacity of the data center so you can respond to your increasing requirements, in order to optimise the CAPEX/OPEX.

Two concepts should be considered in order to be able to meet a data center's increasing needs:
