Solutions and Applications
You use the Solutions and Applications panel to access vCenter Server extensions installed in your vCenter
Server System. For example, you can access the VMware vCenter Guided Consolidation extension and the
VMware vCenter Update Manager from this panel.

This panel appears only if you purchased and installed VMware vSphere extensions that are sold
separately from the VMware vCenter Server product.
Managed Components
Managed components are objects in your virtual and physical infrastructure on which you can place
permissions, monitor tasks and events, and set alarms. You can group most managed components by using
folders to more easily manage them.
All managed components, with the exception of hosts, can be renamed to represent their purposes. For
example, they can be named after company departments or locations or functions. vCenter Server monitors
and manages the following components of your virtual and physical infrastructure:
Clusters
A collection of ESX/ESXi hosts and associated virtual machines intended to
work together as a unit. When you add a host to a cluster, the host’s resources
become part of the cluster’s resources. The cluster manages the resources of all
hosts.
If you enable VMware DRS on a cluster, the resources of the hosts in the cluster
are merged to allow resource balancing for the hosts in the cluster. If you enable
VMware HA on a cluster, the resources of the cluster are managed as a pool of
capacity to allow rapid recovery from host hardware failures.See the Resource
Management Guide.
Datacenters
Unlike a folder, which is used to organize a specific object type, a datacenter is
an aggregation of all the different types of objects needed to do work in virtual
infrastructure: hosts, virtual machines, networks, and datastores.
Within a datacenter there are four separate hierarchies.
n
Virtual machines (and templates)
n
Hosts (and clusters)
n
Networks
n
Datastores
The datacenter is the unit of virtualization (the namespace) of networks and
datastores. Within a datacenter, you cannot have two objects (for example, two
hosts) with the same name but you can have two objects with the same name
in different datacenters. Virtual machine names need not be unique within the
datacenter, but must be unique within each virtual machine folder.
If two virtual machines connect to networkA, they are connected to the same
network. Rules are different across datacenters. Theoretically, the same
physical network can appear in two datacenters and be called two different
names. Or networkA might have one meaning in datacenterA and a different
meaning in datacenterB. Moving objects between datacenters can create
problems or, at least, unpredictable results.
