Plan how you will set up your virtual environment. A large vSphere implementation might contain several virtual datacenters with a complex arrangement of hosts, clusters, resource pools, and networks. It might involve multiple vCenter Server systems in Linked Mode. Smaller implementations might require a single virtual datacenter with a much less complex topology. Regardless of the scale of your virtual environment, consider how the virtual machines it will support are going to be used and administered.
Here are questions you should answer as you create and organize an inventory of virtual objects:
Will some virtual machines require dedicated resources?
Will some virtual machines experience periodic spikes in workload?
Will some virtual machines need to be administered as a group?
Do you want to use multiple vSphere Standard Switches, or you want to have a single vSphere Distributed Switch per datacenter?
Do you want to use vMotion and Distributed Resource Management with certain virtual machines but not others?
Will some virtual objects require one set of system permissions, while other objects will require a different set of permissions?
The left pane of the vSphere Web Client displays your vSphere inventory. You can add and arrange objects in any way with the following restrictions:
The name of an inventory object must be unique with its parent.
vApp names must be unique within the Virtual Machines and Templates view.
System permissions are inherited and cascade.
Tasks for Organizing Your Inventory
Populating and organizing your inventory involves the following activities:
Add hosts to the datacenters.
Organize inventory objects in folders.
Setup networking by using vSphere Standard Switches or vSphere Distributed Switches. To use services such as vMotion, TCP/IP storage, Virtual SAN, and Fault Tolerance, setup VMkernel networking for these services. For more information, see vSphere Networking.
Configure storage systems and create datastore inventory objects to provide logical containers for storage devices in your inventory. See vSphere Storage.
Create clusters to consolidate the resources of multiple hosts and virtual machines. You can enable vSphere HA and vSphere DRS for increased availability and more flexible resource management. See vSphere Availability for information about configuring vSphere HA and vSphere Resource Management for information about configuring vSphere DRS.
Create resource pools to provide logical abstraction and flexible management of the resources in vSphere. Resource pools can be grouped into hierarchies and used to hierarchically partition available CPU and memory resources. See vSphere Resource Management for details.
