The Hevert-Arzneimittel GmbH & Co. KG produces and distributes homoeopathic medicines. This involves enormous logistic efforts which can only be managed by means of modern information technology. Since May 2011, Hevert-Arzneimittel has been using a modern IT-landscape: three new and more efficient servers take on the work that 21 gradually upgraded servers had to carry out so far. In addition to the mere savings in space and material, also an improved utilization of the servers of 65 percent is achieved. Thus, with the modernization and optimization of the air-conditioning system, Hevert reduces its electricity demand in administration by almost half.
