Hi.
We have an application on redhat with hight usage of cpu.
For now, we use serveur with 4 CPU QuadCore, then 16 core.
We think about usage of virtualisation for this application.
I saw that standard licence ESXi has limitation of 4vCPU...
Can I make a VM with 16 vCPU with ESXi, or other vmware product ?
There is a licence special for this ?
Scalability is good ? Or it is better not use vmware for this usage ?

8-way SMP is currently the maximum supported by ESX and that will require the licensed product (i.e. not the "free" license). There is speculation that this number will go beyone 8-way in the next release, but there are no guarantees. Typical virtualization applications are scale-out, not scale-up for that reason. However, you can assign that 8-way virtually in a few ways:
1x 8-core vCPU
2x 4-core vCPU
4x 2-core vCPU
8x 1-core vCPU
Use the advanced cpuid.coresPerSocket parameter to configure. I have more detail on that issue in my blog post:

ESX 4 supports maximum of 8-way vSMP. So, you can not currently create a virtual machine with 16 vCPU.
