vCenter Server installation

Eventhough we purchased the vSphere Essentials, but we only have 1 physical server that running 3 vm on it. So in this case, is the vCenter Server still helpful? or I can just use the  VMware vSphere Client?

And if I need to install vCenter Server, do I have to install on the vm or I can install on any one of the physical machine? and does the machine has to be joined to the domain?

lots of disadvantages,

1. are you familair with Linux administration.
2. there have been many support issues with the database.
3.No Update Manager
4.No Linked-Mode
5.No support for the VSA (vSphere Storage Appliance)
6.Only support for Oracle as the external database
7.Embedded database, DB2, only supports 5 hosts and 50 VMs
8.No support for vCenter Heartbeat

Now many have decided to use the vCenter appliance to save on a Windows cost of the license, but have then decided to use the Windows version instead, until the issues have been fixed. Maybe in vCenter Appliance 5.1! (End of August 2012!)

I would not recommend it at present.

vCenter can be installed on a VM, and vCenter is needed for clustering which IIRC is not included with the essential edition
vCenter will offer you additional features that standard ESXi does not offer. For example, in vSphere Essentials, it gives you 1) Update Manager - Allow you to patch or update your ESXi host. 2) VMware Data Recovery - Allow you to backup your VMs, if you don't have any backup software.

vCenter can be install as VM or physical machine.  Its depends on your need and level of protections.  vCenter does not need to be joined to the domain.  You can join it to domain, if you want to use Domain authentication.

Hope above info helps.

Update Manager won't do you much good if you're running vCenter on a VM as it can't patch the host with running VM's

Hi Friend,
from VC Center you can perform more administrative task.
like HA,FT, single instance of all esx and many more...
in one word you can say that vccenter will help you in esx administration

and vc center can be installed on vm or physical.
it should me in domain.

Frankly VM can do maybe 1 or two tricks in this case but not much.

vCenter Server with a single ESX host, can still be beneficial.

You can install vCenter Server on a physical or virtual server, both are supported.

It can be joined to the domain or standalone server. That would depend on which accounts you would like to manage your ESX host server.

my is essential kit looks like it doesn't provide backup solution...
so what's the benifit o using vcenter in my case?

do you have shared storage a SAN? how manys servers?

It can monitor and manage your performance of your hosts, and the data will be stored in a database. Otherwise you will only have access to realtime data for 24 hours. Setup Alerting, Integrate with Active Directory, for easier User Management and Access.

Access Host Servers via iPad, Web Client (browser)

Create and Deploy Templates, Clone Machines and Templates. Migrate Virtual Machines, it's much easier with the Management vCenter Server.
Vcenter monitor the health and perform fail over if neccesary . Backup software will also required to intergrate with vcenter to perform advance backup functionality / administration

Just found out that there is another option of installing vcenter server by using the vCenter Server Linux Appliance. Is this a good option instead of installing it on top of windows system? any disvantage?
Using vcenter appliance, you save cost on Windows Server license.
