esxi is only the hypervisor. It is a linux like program (command line driver). It is not that easy to manage it directly.

But in vsphere you get a Windows program called Vcenter which is used to control and manage several ESXi together.

VMware vSphere Hypervisor (ESXi) is what VMware calls the FREE version.

VMware vSphere Essentials is the Licensed version, which contains 3 Licenses for 3 Host (ESXi) servers and a Licence for the Management Server vCenter Server.

Only 3 hosts? That's well over 100 virtual machines, how many do you need? Bear in mind with Windows VMs you either have to license them for every host they might run on or license per-CPU using datacenter licenses - e'g. 3 hosts, 4VMs=12 Windows Standard licenses.

My bad, forgot Essentials was limited to 32GB vRAM per host, that's still quite a lot of VMs though.

I see.. so the host is physical machine which I can install the VMware vSphere Essentials on each. is it unlimited vms per host?
you also mentioned it's 32gb ram per host.. what does this mean in the link? 32GB (192GB total) 192 gb total???
http://www.vmware.com/products/datacenter-virtualization/vsphere/small-business/compare-kits.html

I am currently using the free edition of VMware vSphere Hypervisor ESXI. I am able to manage all my vms through the VMware vSphere Client. So with the VMware vSphere Essentials do I still need to install the VMware vSphere Client? and is the main advantage is that I can manage 3 physical host within 1 interface?

With Essentials you get vCenter which allows you to manage all 3 hosts and looks almost exactly like the vSphere client. Additionally it allows you to build templates and perform vMotion among other features.

Regarding vRam entitlement, for Essentials it's 32GB per CPU. Essentials gives you a licenses for 6 CPUs total (still max 3 hosts though) so that's a total of 192GB.

So for one host with 2CPUs you can only have 64GB of RAM in use. Not necessarily available RAM, just RAM used by your VMs in that host. So for example, that server may have 96GB of RAM physically installed, but you are licensed to only use 64GB for your VMs. It's not currently enforced by any means, but thats your limit on RAM to be in compliance.

Correct, but you will need to install vCenter Server on a physical or virtual server, for management of ALL Hosts from one vSphere Client.

I only have 1 physical server (HP proliant dl380p) with 2 physical cpu...
so do you recommend I install the vCenter Server on the same vm host or better install on other physical machine? And do I still need to install vSphere Client?

In the attachment is the vm I am goign to install on this physical server. Please let me know if this make sense. Appreciate it!

Since you only have one server, I would suggest you still install both vCenter and use the vSphere client.

Install vCenter on a VM in that host, and use it as your main console.

However, when you power off the host for maintenance or what not. If you don't have the vCenter machine automatically powering up or if you have problems with that VM, then use the vSphere client to connect to the host and turn on the vCenter machine or power it on.

But I would still use the vCenter client as your main console. Only feature I can think of that's going to be useful is deploying VMs from templates, but even just that would save you loads of time than just using the vSphere client. Of course, there's more features on vCenter, but that's the only one I can think of off the top of my head that's really usefull. (That and vMotion, but since you only have one host you'll only be able to move storage)

Once you get a second host you can create a cluster and start using stuff like HA and DRS.

vCenter is supported on physical or virtual?

how many hosts are you installing, do you have shared storage?

okamonAuthor Commented:
I guess I would install both the vCenter Server and vSphere Client on different physical machine. As I want to save as much as the resource as possible on the host.

We are goign to use the raid 1 for the vm OS and another raid 10 for vm storage.
Have anyone had any chance to look at my attachment yet (my previous post)? I just want to know if that make sense.

Don't have anything to open it with at home.

Someone will hopefully confirm whether you can combine all your vRAM entitlement onto the single host so that you can put a decent amount of RAM in the server, 8GB dual rank RDIMMs are still the sweet spot for price as far as I know.

Something's screaming to me "drop a CPU and spend the money on an iodrive or at least SSD instead" for squeal server's data, but will have to confirm vRAM entitlement with only 1 CPU present.
