1) This is related to the VMware ESX 4
2) There is one Host --> VMWare#1 (the IP:
3) I connect to this VMware host using by typing -->
- Then, I can install the vSpere (or VI client)
- This functions as a management console ....I can do anything with the Host (VMware#1): creating the vm machines, etc

4) There is something similar with the vSpere called "vCenter"?
5) I am still confused with this "vCenter"?
- How to install it?
- How to get the software for it? (by connecting to the VMWare# 1 as above) or (It is totally "separate software" that we can download?
6) Would tell me the difference between the vSphere and vCenter?

vSphere client is a tool to connect to VMware host, or to a vCenter Server.

A vCenter is tool that will manage your VMware hosts, your VMware cluster High Available etc.

Check here:


With vSphere Client you will connect and manage your VMware host, or vCenter.

vSphere is just the name of the infrastructure.
vCenter Server is the management tool (you need a license to install it)
ESX is the hypervisor.

Here is a good reading on how to install the vCenter: http://www.vmadmin.co.uk/vmware/36-virtualcenter/263-vcenterinstall41

1) If I have got the vCenter, I do not need the vSphere anymore, right?

Of course you need.

vCenter is to manage ESX vSphere hosts and create VMware Clusters etc. vSphere client is just o connect to VMware host or vCenter trough a graphic environment. You can manage the hosts by command, but this is for very advance VMware technicians.

Please read the links.

You will always need the VMware vSphere server(the VMware host) and the vSphere Client to connect this servers.

If you want to use a more advance VMware implementation, you will use vCenter Server and vSphere is also to connect to this vCenter server.

Again read the links to understand this.

1) OH ... I see
2) So for example, I have ESX hosts
- VMWare#1, VMWare#2, VMWare#3, VMWare#4
- To make the VMware Clusters, etc of this 4 ESX hosts --> I have to use the vCenter, right?

3) Then, To each host itself ; for example VMWare#1
- If I want to create vm machine#1, vm machine#2, vm machine# 3, etc --> I have to use the vSphere, right?

4) So It means that every ESX Host has its own vshpere, right?
For example:
- VMware#1 has vsphere --> say it vsphere#1
-VMware#2 has vsphere --> say it vsphere#2
- Is it right?

5) Post it back please

6) Thanks
