Hardware for TeskaLabs LogMan.io

This is a hardware specification designed for vertical scalability. It is optimised for those who plan to built an initial TeskaLabs LogMan.io cluster with the lower possible cost yet with the possibility to add more hardware gradually as the cluster grows. This specification is also fully compatible with the horizontal scalability strategy, which means adding one or more new server node to the cluster.
