This section lists pre-requisites for a VI workload domain.
- A DHCP server must be configured on the NSX-T host overlay (Host TEP) VLAN of the workload domain. When NSX-T creates Edge Tunnel End Points (TEPs) for the VI workload domain, they are assigned IP addresses from the DHCP server.
- A minimum of three hosts marked with the appropriate storage must be available in your Cloud Foundation inventory.
- To create a VI workload domain with NFS storage, the hosts must be commissioned with NFS as the storage type and must be associated with an NFS network pool.
- To create a VI workload domain with vSAN storage, the hosts must be commissioned with vSAN as the storage type and must be associated with an vSAN network pool.
- To create a VI workload domain with VMFS on FC storage, the hosts must be commissioned with VMFS on FC as the storage type and must be associated with a vMotion only or vMotion and NFS network pool.
- There must be a free pNIC on each host to be used for the workload domain.
- To create a VI workload domain that uses vSphere Lifecycle Manager to apply cluster images to all hosts in the cluster, you must have a cluster image available. See Cluster Image Management.
- If the management domain in your environment has been upgraded to a version different from the original installed version, you must download a VI workload domain install bundle for the current version before you can create a VI workload domain. See Download an Install Bundle.
- Decide on a name for your VI workload domain. Each VI workload domain must have a unique name. It is good practice to include region and site information in the name because resource object names (such as host and vCenter names) are generated based on the VI workload domain name. The name can be three to 20 characters long and can contain any combination of the following:
Note: Spaces are not allowed in any of the names you specify when creating a VI workload domain.
- Lowercase alphabetic characters
- Uppercase alphabetic characters
- Decide on the following passwords:
Although the individual Cloud Foundation components support different password requirements, VMware recommends that you set passwords following a common set of requirements across all components:
- vCenter Server root password
- NSX-T Manager admin password
- Minimum length: 12
- Maximum length: 16
- At least 1 lowercase letter, 1 uppercase letter, a number, and one of the following special characters: ! @ # $ ^ *
- Must NOT include:
- A dictionary word
- A palindrome
- More than four monotonic character sequences
- Three of the same consecutive characters
- Gather the information that you need for the workload domain creation workflow.
Table 1. Information Required vCenter IP address and FQDN Three NSX Managers IP addresses and FQDNs NSX Manager Virtual IP (VIP) address and FQDN
- The IP addresses and Fully Qualified Domain Names (FQDNs) for the vCenter and NSX Manager instances must be resolvable by DNS.
- If you are using NFS storage for the workload domain, you need the following information:
- Datastore name
- Path to the NFS share
- IP address of the NFS server
- If you are using VMFS on FC storage for the workload domain, you must create the datastore on the hosts and configure zoning and mounting of associated volumes.
- You must have valid license keys for the following products:
- NSX-T Data Center
- vSAN (No license required for NFS or VMFS on FC)
Because vSphere and vSAN licenses are per CPU, ensure that you have sufficient licenses for the ESXi hosts to be used for the workload domain. See License Management.
