The Aiolos software is quite small and does not need a lot of disc-space, The executables will need max 100 Mbyte and 1 Gbyte is enough for the data. The system will run on anything capable of running Windows, but will of course run faster on a faster machine. We recommend a 2 GHz processor and 2 Gb RAM for a good performance. A fault tolerant disk system, like RAID-5, is always a good idea.
