A workload domain (WLD) consists of one or more Dell VxRail clusters that are managed by one vCenter Server instance. WLDs are connected to a network core that distributes data between them. WLDs can include different combinations of VxRail clusters and network equipment, which can be set up with varying levels of hardware redundancy.
From the VxRail clusters, you can organize separate pools of capacity into WLDs, each with its own set of specified CPU, memory, and storage requirements to support various workload types such as Horizon or business-critical apps like Oracle databases. As the SDDC Manager adds VxRail physical capacity, the capacity is made available for consumption as part of a WLD.
Two types of WLDs can be deployed:
The following section provides more detail about each type of WLD.
