ESXi Licensing...

I have just started to use Vmware ESXi today and I have a question regarding the license for it. On the bottom of the license page it says: ", but is restricted to deployment on less than or equal to 2 CPUs.".....what do you mean by 2 CPU's? Does that mean I can use it on a dual quad core server and be able to use all eight cores?? Right now I have it installed and running on a single quad core system. When I applied my license serial number it said that I am licensed for 1 CPU.

I guess I am just confused, if anyone can explain further the licensing for ESXi I would appreciate it. I looked everywhere!

Thanks so much!

Yes 2 CPU means 2 physical CPUs - so if you have a duel quad core cpu you will have 8 cores you can use - it indicates you are licensed for one CPU because that is all your using but you still have access yo all 4 cores - hope tha answers your question -

Exactly the answer to my question, I just was unsure of VMware's definition of 'CPU's', plus when I applied the license I was unsure of why it said Licensed for 1 CPU, but it does make sense, since I only have one SINGLE quad CPU, and I was assuming that it meant TWO PHYSICAL CPU's with 4 cores each.

Thanks for your help!!

Thats weird 'cause i'm using a dual-core but i still am getting 'Processor sockets: 1' and 'Processor cores per socket: 1'.... that is on the ESXi-free version (=Dell PowerEdge 850 with an Intel Dualcore 3Ghz and VMware Infrastructure Client). ?!

regards,

Do you have ESXi licensed or still in demo mode? What specific model of CPU do you have?

I've inserted some screenprints below with the relevant information from the configuration tab in VM Infrastr. Client. If you need more info please tell me.

Looks to me like you have only one CPU - why do you think you have 2? That Pentium-D is a hyperthreading processor, not multicore and definately not capable of supporting dual CPU's on a motherboard

I've been in contact with Dell technical support and it has two cores but apparently no virtualisation support and thus will show up as one cpu (according to them). Weird thing is though when using vmware server on this machine i am sure i had assigned the cores to different virtual machines.....

Anyhow, thanx for the answers !!

I think it is still odd.... i temporarily installed CentOS linux and here is the output of dmesg about the number of cpu's (and at the end it says: 2 cpu's) :

I'm to unfamiliar with VMware to understand how it sees the number of cpu's but i'm reading two cpu's here ?!

Thanx!

As I remember someone having it here and there was needed bios updates (although I think it is not supported/Pentium D).

Hi,

Looks to me like you have only one CPU - why do you think you have 2? That Pentium-D is a hyperthreading processor, not multicore and definately not capable of supporting dual CPU's on a motherboard

I think that's not quite correct. A Pentium D certainly is a Dual Core CPU (basically two Pentium 4 cores nailed onto one die).

<[http://en.wikipedia.org/wiki/Intel_Pentium_D]>

Never tried ESX on one though.

what if you have are using a 4 socket quad core? i know the core doesn't matter, but what if you are using a 4 socket server (i.e. DL585) Does that mean esxi is not longer free? if there is a charge, would i be charge for 4 CPU license or 2 ?

This answer from Dell seems a bit bogus. You host should report one physical slot, 2 CPU cores and 2 logical CPUs. As chritianZ mentions, try a BIOS upgrade if available. I also recall a thread this week in which that was the solution.

I'm almost certain i'm using the latest BIOS, but will check that just to be sure.

When you run ESXi in standalone (free) mode, then you can run as many CPU cores as ESXi / ESX can support (i.e. up to 32 cores / 32 logical processors).
