We are an advocate of ecological and economic principles when deciding whether to purchase new hardware. In our opinion, you should only purchase new equipment if the IT infrastructure either no longer meets the requirements or you are running into a capacity bottleneck. Unfortunately, many companies exchange their equipment because the manufacturer puts pressure on them by discontinuing support for hardware that is still functional. This term is called End of Life ( EOL ) or End of Support ( EOS ). With the preliminary stage End of Sale, the customer is already signalled that, for example, the server or the storage is no longer sold. After three to seven years they stop the support it at all.
