A WLD represents a logical boundary of functionality, managed by a single vCenter server instance. Although a WLD usually spans one rack, you can aggregate multiple WLDs in a single rack in smaller setups. In larger configurations, WLDs can span racks.

The following figure shows how one rack can be used to host two different WLDs, the Mgmt WLD and one tenant WLD. Note that a tenant WLD can consist of one or more clusters, this will be discussed later.

Figure 6.              Single Rack WLD Mapping

A single WLD can stretch across multiple adjacent racks. For example, a tenant WLD that has more VxRail nodes than a single rack can support, or the need for redundancy might require stretching across multiple adjacent racks, as shown in Figure 7.

VxRail hardware options

Depending on the management workload and the tenant workload and application requirements, the right VxRail hardware platform must be selected. The VxRail HCI family provides the following offerings for all types of workloads.
