VMware NSX-T requirements Complete the following requirements for VMware NSX-T before using your Dell EMC PowerOne System. PowerOne uses VMware NSX-T for network virtualization on the VMware vCenter Server in the production environment. NSX-T is an optional feature of PowerOne. To understand the requirements for the physical network and cluster to use NSX-T in your PowerOne, see the relevant VMware Validated Design, at the VMware website. Note the following: NSX-T only supports the BGP routing protocol. Redundantly connect the top-of-rack (ToR) switches and your switches to ensure that they are available during a switch failure. The maximum transmission unit (MTU) value that is specified on your switches must be identical to the value configured on the ToR switches. The supported MTU is 9000.
