Create Datacenters
A virtual datacenter is a container for all the inventory objects required to complete a fully functional
environment for operating virtual machines. You can create multiple datacenters to organize sets of
environments. For example, you might create a datacenter for each organizational unit in your enterprise or
create some datacenters for high performance environments and others for less demanding virtual machines.
Prerequisites
n
Open a vSphere Client session to a vCenter Server.
n
Verify that you have sufficient permissions to create a datacenter object.
NOTE Inventory objects can interact within a datacenter, but interaction across datacenters is limited. For
example, you can hot migrate virtual machines from one host to another host in the same datacenter, but not
from a host in one datacenter to a host in a different datacenter.
Procedure
1 Go to Home > Inventory > Hosts and Clusters.
2 Select File > New > Datacenter.
3 Rename the datacenter.
What to do next
Add hosts, clusters, resource pools, vApps, networking, datastores, and virtual machines to the datacenter.
Add Hosts
You can add hosts under a datacenter object, folder object, or cluster object. If a host contains virtual machines,
those virtual machines are added to the inventory together with the host. Information about configuring hosts
is located in the vSphere Networking, vSphere Storage, vSphere Security, and vSphere Host Profiles documentation.
Prerequisites
n
Open a vSphere Client session to a vCenter Server.
n
Verify that you have sufficient permissions to create a host object.
n
Verify that a Datacenter, folder, or cluster exists in the inventory.
n
Obtain the user name and password for an account with administrative privileges on the host.
n
Verify that hosts behind a firewall are able to communicate with the vCenter Server system and all other
hosts through port 902 or other custom-configured port.
n
Verify that all NFS mounts on the host are active.
Procedure
1 Select Home > Inventory > Hosts and Clusters.
2 Select a datacenter, cluster, or folder within a datacenter.
3 Select File > New > Add Host.
4 Enter host name or IP address and administrator credentials and click Next.
