Green IT

Just because it says Green IT on the outside doesn’t mean that it’s Green IT on the inside. Our customers’ IT infrastructure solutions do more than justice to today’s environmental requirements. This has been achieved by implementing an ‘Ecology principle’: a consideration of ecological aspects is no longer just ecologically sound but also profitable.
 

Integrated planning
The environmental friendliness of companies is governed by a cost-benefit calculation. Thus, the biggest opponents to Green IT solutions are the acquisition costs, since the necessary investments are usually higher than those for conventional IT solutions. T&N draws up a 5-year, full-cost calculation for its customers, which puts the investment costs into perspective and permits an integrated planning of the relevant IT infrastructure. For example, the operating costs of IT infrastructures are a cost factor that is often ignored in several procurement projects, even though they effectively represent a key factor in the overall costs.

Consolidation
Any Green IT project revolves around a stocktaking of the total infrastructure that either exists or is needed (server, clients, network, printers, software and accessories). A target model of the IT infrastructure can be prepared on the basis of this inventory whose goal is to standardise as many of the existing subsystems as possible both logically and physically in the same IT infrastructure. This normally leads to a drastic reduction of the required infrastructure components:
  • The relevant components can be dimensioned more specifically for the requirements by segmenting performance (processors and RAM) and capacity needs (hard disk memory). This guarantees not only a greater clarity but also a drastic increase in energy efficiency.

Virtualisation
The consolidation of IT infrastructures to a few, more efficient components allows the optimum implementation of new virtualisation technologies. Systems such as Exchange Server, Print Server, Domain Controller or SAP Server can be migrated to virtual machines and thus decoupled from the server hardware. The virtualisation technology serves as an abstraction layer that permits the operation of one or more virtual machines on a single physical host server. This in turn means that several virtual servers can be combined into a resource pool. Should one of the physical hosts fail, the virtual machines running on this are automatically distributed to other hosts where they are restarted.

Intelligent components save energy 
Low-voltage processors in servers or thinclients as user terminals are just two examples of excellent ways to save energy.
Not forgetting the intelligent networks that allow you to control the power supply for IP telephones. The new class 1 POE IP telephones use four times less power than a class 3 device.

Products from sustainable production
The ecology principle can ultimately be implemented with special regard to the environmental compatibility and sustainable production of the relevant component manufacturer.

So you see, it pays to use Green IT, for both you and the environment!
