1-6 core per CPU
Posted on 2012-12-23
Any expert out there to explain the terminology used in Vmware language:
it says one single server can use 1-6 cores per CPU.
If I understand, a core is just a block, for instance, when we say :
Dual core processor= one block that has 2 processors inside
Quadro core processor=one block that has 4 processors inside.
I don't think :
1-6 cores per CPU means one block can have 1 to 6 CPUs inside.
any clarifications?
thanks

Depending upon the CPU user in a server, it could be a processor which has Dual, Quad, Six Cores per physical processor or socket.
New Xeon processors in the future could have 50 cores per processor!

A core is an independant CPU, original processors were a single core unit, today, it's common place to have multiple CPUs inside the die (case).
So the metal thing you put in a socket, has multiple CPUs (cores) inside it.
So, yes, 1-6 Cores, does mean it actually have 1-6 CPUs inside it!
because technology has made things smaller, hence the description of technology in
nm.
if you look at the Processors Lithography, you will see it's getting smaller!
e.g.
http://ark.intel.com/products/63696
32nm
http://ark.intel.com/products/27259/Intel-Xeon-Processor-1_40-GHz-256K-Cache-400-MHz-FSB
180nm
e.g. a little off topic, but latest GPUs (graphics chips) have 512 or 1024 Cores on a single CHIP!
In a VMware Context, this means, that you can use 1 CPU (a vCPU) in the virtual machine, is equal to 1 Core on the physical host, for some of the time. (the scheduler will move the process from Core to Core in the physical server).

When referring to Cores, you are mostly correct. We are talking about CPUs in a CPU *socket*. So, for example, if you were to pop the hood of your physical server, you may see 1 or 2 CPU "sockets". Now, within those sockets, you might have embedded CPU *cores* that total anywhere from none (just the CPU socket itself, but that is rare to non-existent these days), to up to 12 (I actually have dual socket, 12-core servers in my environment). So, if you have a dual socket 6-core CPU server, that in essence provides 12 CPUs for your virtual environment. If you have Hyperthreading enabled in your BIOS, that basically doubles the CPU to 24 (Hyperthreading allows multiple "threads" of processes over a single core).
Hope that helps...

So:
1-6 cores per CPU= 1-6 processors in one CPU socket
Dual core processor= 2 processors in one CPU socket
Quadro core processor=4 processors in one CPU socket
1-6 cores per CPU= 1-6 processors in one CPU socket
Dual core processor= 2 processors in one CPU socket
Quadro core processor=4 processors in one CPU socket
