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

Figure 9 above shows that one of the three control plane modes must be selected when creating a

transport zone via NSX Manager vCenter plug-in. As mentioned prior, a transport zone defines the

boundaries of a logical network/switch. Hosts are added to the transport zone at the cluster level. Below,

the three clusters being added to the transport zone are Edge, Productions Site A (Compute), and

Production Site B (Compute).

Defining of the transport zone, replication mode selection, and VXLAN configuration is the second step of

NSX deployment. Once this configuration is done all other configuration of defining logical components

(logical switch, DLR, DFW, logical load balancers, etc.) can be done repetitively via manual process or API

calls. The next section details the physical network architecture as well as the logical components that are

utilized to achieve three tier application provisioning in a flexible, consistent, and dynamic method.

6 A Dell End-to-End Converged Infrastructure for VMware

NSX

As we now have a basic understanding of VMware NSX and the respective logical components and

interactions, we next take a look at a complete Dell end-to-end converged infrastructure used to deploy

VMware vSphere-only NSX. For specific installation requirements and detailed deployment steps please

see the Dell Infrastructure with VMware NSX Deployment Guide.

6.1 Converged Underlay Infrastructure with DCB and iSCSI

Figure 10 below displays a Dell converged infrastructure underlay for VMware NSX. Depending on

requirements and the desire to use an already existing infrastructure, Dell and VMware provide flexibility to

support many different L2/L3 or hybrid L2/L3 underlay deployments.

Although VMware NSX is agnostic to the type of storage utilized in the network, it must be taken into

account that the storage traffic is not virtualized and depending on what type of storage is used (iSCSI,

FCoE, FC, NAS), this may affect the network underlay design of the overall solution. Note, at present ESXi

iSCSI multi-pathing requires a non-routed network between the host and the iSCSI storage (for details, see

the following VMware Knowledge Base article: http://kb.vmware.com/kb/1009524). In the setup shown in

Figure 10, iSCSI storage to host multi-path connectivity is achieved via Layer 2 connectivity which also

take advantage of DCB to provide for a lossless converged fabric.
