How much resource is cost for the ESX Server.

Hi Friends,

I have some questions about the resource utilization of the ESX Server.

1) Surpposed we have a 32GHZ cpu, esx Server. How much GHZ can be used by the Virtual Machines? 32GHZ * 10%?

2) When all the virtual machine are use the resource to 50%, does it mean the ESX Server's resouce utilzation is 50%?

Thanks.

If the VM only has 1 virtual CPU, the VM will only use one of the core's total processing power. You can't span a single virtual CPU across multiple core.

If a VM needs to use the CPU for some work, ESX will schedule the VM to put that onto 1 core until 20milliseconds has past and then ESX decides if it needs to continue using that CPU.

So if 1 core of your server is 2Ghz, and the VM has 1 virtual CPU, the VM will use 2ghz of CPU.

2) What resource are you talking about? CPU? Network? Memory? Disk?

thanks

I means the Cpu and mem?

If the VM is at 50% cpu and memory usage, that is just 50% of the resources that are assigned to that VM, not 50% of the ESX resources
