Logical processors esxi

[FelixCent]

Hi everyone.

I know that there are a lot of documentation about the issue, but all this information is making me feel even more confused.:smileyplain:

The question is simple:  " in esxi 5.5"

• NO HyperThreading
• Intel Xeon CPU E5-2407 v2
• processor socket 1
  
• Cores per socket 4
• Logical processors 4.

How many virtuals machines can I run?

As I understand just 4.One per logical Processors.  But I am running 5,,,so I do not understand properly the issue.

Thanks everyone

Hi,

the amount of VMs you can run is more limited by the amount of RAM you allocate to the VMs, since every VM you start needs at least some RAM to boot.

ESXi has no problem with using a logical core for multiple VMs.

When you create more and more VMs, each logical core will have to serve X vCPUs. If this is good or not depends on your applications and their need for ressources.

I'm running up to 5 vCPUs per logical core in our environment and it's running fine since the applications don't need much CPU time.

Plus the disk space will also be your limitation too
