19 Network Virtualization with Dell Infrastructure and VMware NSX | Version 1.2

6.2 Management, Edge, and Compute Clusters and VDS

Note, in the hybrid blade/rack server deployment in Figure 10, all management and edge servers are rack

servers; this allows for ease of management and scale for management and edge servers which will

typically be located in management / edge racks. Also, by having all edge devices on rack servers in a

hybrid environment, traffic flow will always be predictable when bridging from logical to physical and

routing North-South traffic. Although rack layout can vary depending on size, space, and topology, a

typical rack layout with VMware NSX is shown in Figure 11 below.

Note, the separate racks for compute and the combined racks for management, edge, and storage. Often,

the management, edge, and storage racks are combined as shown or edge is separated from

management and storage. In a converged fabric as displayed in Figure 10, it is typical to connect the

storage centrally for better distribution and scale across all hosts/clusters; as ToR switches are added, they

simply connect to the core S6000 switches and have access to all centralized storage.

Figure 11 Typical rack layout for compute, management, and edge servers/clusters. Storage can be centrally

connected to the core as in a completely converged fabric design or connected to ToR dedicated

storage switches at EoR for a typical non-converged design as often shown with Fibre Channel or

dedicated iSCSI storage.

As mentioned prior, the transport zone defines the span of a logical switch/network. Correspondingly,

management hosts never have to be part of the transport zone as logical networks should not span across

management hosts. However, logical networks will span across compute cluster(s) as the VMs and

workloads will be on the hosts in compute cluster(s).
