In scope of the Wigner Datacenter cloud project we are consolidating our network equipment. According to our plans we would like to purchase 100 Gbps datacenter switches in order to anticipate our current and future needs. We need automated, vendor neutral and easily operable network. This presentation highlights our requirements and design goals, candidates we have tested in our lab. We take the opportunity here to introduce our knowledge lab initiative where we can expand the scope of testing solutions.
