Each Edge Bare Metal size server has four 25-Gigabit Ethernet interfaces, with two interfaces on each of two separate NIC cards. By default, all four interfaces are placed into a single link access group (LAG) or bond utilizing LACP for individual link monitoring.
Each server connects to two switches: 2x 25GE to switch A and 2x 25GE to switch B. These switches are located in the same physical rack as the server. Each of these switches have multiple 100GE fiber connections to multiple other switches in the data center that create an ethernet switching fabric. This switching fabric can sustain full traffic capacity with any single switch or link failure.
