I recently purchased vSphere Essentials 4.0 and am basically happy with it. Before purchasing I was told that it supports up to 2 CPUs each with up to 4 Cores each. Any reasonable person would take that to mean that you can create Guest machines with up to 8 Virtual Processors (VCPUs). However after installing I found out that I could only create machines with up to 4 VCPUs! (I take that back - I can create them, but they won't run
)
When I brought this up to the sales rep, he gave me some reasons that I still can't understand and then gave me an extremely expensive option for getting up to 8 VCPUs: over 4 times the price of the original vSphere. I still don't understand how vSphere can claim to support up to 8 cores, but only allow you to run VMs with up to 4 cores.
I have gone back and re-read the literature and still cannot find anything stating this limitation. Can someone 'splain this to me? I think VMWare owes me another 4 VCPUs.
Enterprise plus is the only licence that offers 8 vcpu, they may have been refering to your licence can go on 2 cpu's with 4 cores each. but I thought it was up to 6 cores per cpu..
there is a document around showing the differences, http://www.vmware.com/files/pdf/vsphere_pricing.pdf I know this one but im sure ive seen better
Cheers

Correct vSphere can support vSMP up to 8x vCPU per VM. However Essential only up to 4 vCPU. Check this Comparison
vcbMC-1.0.6 Beta
vcbMC-1.0.7 Lite
thats the better one ^^^ I was talking about ![]()

Thanks, but I still don't get it. Where in this document is it telling me that I am limited to 4 VCPUs on a Virtual Machine?
See the line that says 'vSMP' support?

This is really the document you need to review since it covers what is included in each licensing level - http://www.vmware.com/files/pdf/vsphere_pricing.pdf - and you will see only Enterprise Plus will support 8 way virtual SMP -

VMware vSphere Essentials includes:
• VMware ESXi and VMware ESX (deployment-time choice)
• VMware vStorage VMFS
• Four-way virtual SMP
• VMware vCenter Server Agent
• VMware vStorage APIs / VCB
• VMware vCenter Update Manager
• VMware vCenter Server for Essentials
VMware vSphere Essentials is available for USD $995 including
one year of subscription. Support is optional and available on a
per incident basis.
What does VSMP support mean? Am I the only one who was confused to find only four virtual processors per VM?
Well if you plan to buy a product that costs some money and I'm not a 100% sure if I understood the licensing modell right, I'd ask some people (maybe the vmware hotline).
Don't blame the documentation because you mixed up vSMP and the physical cpu licening (up to to 4 cores). VMware got a bunch of documentation and even as a non native english speaker it's no problem for me to understand it. (Lots of documents are available in other languages too)
Well, maybe you had a more conscientious sales rep. I purchased through Dell and was shown/told no such thing. This is the first time I ever saw such a document. I was simply told that it supported up to 2 CPUs with up to 4 cores each.I think it was a bit of a surprise to the Dell sales rep too, because he had to research the problem to get back to me.

That's why you ask questions, you did the right thing by coming on here. Most like CPU is not the problem. 8 vCPU is a lot of CPU, even physical machines don't need that much, that's why Virtual Machines make sense. Most hardware is overkill for single purpose machines.
I would FIRST try your apps with just one CPU, test it see how it works, do some benchmarking. Then try 2, see what the difference is. You will find it's almost no difference going from 1 to 2 (except Linux). Anything beyond 2 is a waste, because of the technology behind how vCPU work. I can guarantee attempting to use 8 vCPU in a machine is a complete waste of time, a VM cannot utilize all of the hardware, for disk, network, and CPU, so those CPU might show up in a benchmark meter, but the host machine will show the CPU are largely underutilized.
Because we use the vSphere for testing our software, not for production software. And we purchased it specifically to allow testing on multi-processor systems.
isnt 4 cpu's enough to test multi proccessor systems?
Some problems don't come to light unless you have many CPUs and tons or RAM, particularly for server software running on an x86 OS
Since vSphere 5.x release, the Essentials license allows you to have up to 8-way vSMP... so if since 2010 you have had stick to the 4.x essential's license you should upgrade it to vSphere 5.x and start using up to 8vCPUs in VMs
Look at the Essentials section...

For vSMP comparison between vSphere 4.x and vSphere 5.x look at:
