Figure 1-3: Logical design Designing a vSphere Network Architecture with the Virtual Connect FlexFabric module The vNetwork Distributed Switch7 (vDS) allows an administrator to create a centralized distributed vSwitch, which share a common networking configuration across hosts. Port Groups are still utilized in this model, but have a different association to host uplink ports. Host uplink ports are added to Uplink Groups (dvUplinkGroup), where a logical association between the dvUplinkGroup and a PortGroup (dvPortGroup) is formed. vDS can service any of the vmkernel functions; Service Console, VMotion, IP Storage, and Virtual Machine traffic. In this section, we will outline the overall vDS design. vNetwork Distributed Switch Design Each pair of redundant pNICs will be assigned to dvUplinkGroups, which then are assigned to a specific vDS. This will simplify host network configuration, while providing all of the benefits of a vDS. Table 2-1 and Figure 2-1 shows which hypervisor networking function will be assigned to vDS configuration.
