difference between VMware vSphere Hypervisor ESXI and VMware vSphere smb?

Here you go:

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.

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???

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?

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!

vCenter is supported on physical or virtual?

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

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.

Here is what I have in attachment:

1-      SQL Server VM:
a.      32 GB Virtual RAM
b.      8 Virtual CPUs
c.      C:\ 60 GB (Reserved for OS), D:\400 GB (Reserved for SQL Database), E:\400 GB (Reserved for SQL Maintenance Plan Backups)
d.      Software requirements:
i.      Windows 2008 R2 ent Edition
ii.      MS Office Pro 2010 64 Bit
iii.      SQL 2008 R2 ent Edition

2-      Report Server:
a.      4 GB Virtual RAM
b.      4 Virtual CPUs
c.      C:\ 60 GB (Reserved for OS)
d.      Software requirements:
i.      Windows 2008 R2 ent Edition
ii.      MS Office Pro 2010 64 Bit
iii.      SQL 2008 R2 ent Edition (Reporting Services)
iv.      Crystal Reports 8.5 Developer Edition
v.      Adobe Acrobat Professional
 
3-      Terminal Server:
a.      8 GB Virtual RAM
b.      4 Virtual CPUs
c.      C:\ 60 GB (Reserved for OS)
d.      Software requirements:
i.      Windows 2008 R2 ent Edition
ii.      MS Office Pro 2010 64 Bit
iii.      Windows 2008 R2 Terminal Server Cals
iv.      Windows 2008 R2 Cals

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.
