maximum of vCPU with ESXi

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 ?

a++  Xavier

Xavier-

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.
