    In order to address the controller VM requirements listed in Table 1 and design architecture described in Cluster Design Overview, the typical physical server specifications are listed in Table 2. Depending on the actual workloads and the data plane traffic requirements, the network interfaces could be 25G/40G versus 10G.

    Note: Blade Server platforms are not supported on Contrail Cloud.
