| availability zone |
Collection of infrastructure components. Each availability zone is isolated from other availability zones to prevent the propagation of failure or outage across the data center. |
| bring-up |
Initial configuration of a newly deployed Cloud Foundation system. During the bring-up process, the management domain is created and the Cloud Foundation software stack is deployed on the management domain. |
| commission host |
Adding a host to Cloud Foundation inventory. The host remains in the free pool until it is assigned to a workload domain. |
| composability |
Ability to dynamically configure servers to meet the needs of your workloads without physically moving any hardware components. You bind disaggregated hardware components (compute, network, storage, and offload components) together to create a logical system based on the needs of your applications. |
| dirty host |
A host that has been removed from a cluster in a workload domain. A dirty host cannot be assigned to another workload domain until it is cleaned up. |
| decommission host |
Remove an unassigned host from the Cloud Foundation inventory. SDDC Manager does not manage decommissioned hosts. |
| free pool |
Hosts in the Cloud Foundation inventory that are not assigned to a workload domain |
| host |
An imaged server. |
| inventory |
Logical and physical entities managed by Cloud Foundation. |
| Lifecycle Manager (LCM) |
Automates patching and upgrading of the software stack. |
| management domain |
Cluster of physical hosts that contains the management component VMs |
| network pool |
Automatically assigns static IP addresses to vSAN and vMotion vmkernel ports so that you don't need to enter IP addresses manually when creating a VI workload domain or adding a host or cluster to a workload domain. |
| patch update bundle |
Contains bits to update the appropriate Cloud Foundation software components in your management or VI workload domain. |
| region |
A Cloud Foundation instance. |
| SDDC Manager |
Software component that provisions, manages, and monitors the logical and physical resources of a Cloud Foundation system. |
| SDDC Manager VM |
Virtual machine (VM) that contains the SDDC Manager services and a shell from which command line tools can be run. This VM exposes the SDDC Manager UI. |
| server |
Bare metal server in a physical rack. After imaging, it is referred to as a host. |
| unassigned host |
Host in the free pool that does not belong to a workload domain. |
| workload domain |
A policy based resource container with specific availability and performance attributes that combines vSphere, storage (vSAN, NFS, or VMFS on FC) and networking (NSX for vSphere or NSX-T) into a single consumable entity. A workload domain can be created, expanded, and deleted as part of the SDDC lifecycle operations. It can contain cluster(s) of physical hosts with a corresponding vCenter to manage them. The vCenter for a workload domain physically lives in the management domain. |
