Ncomputing & Vmware cpu sizing
Posted on 2010-11-28
I planning to implement 2000 ncomputing devices, for one of my customer.
Ncomputing is a sort of thin client, which as no CPU, no disk no memory, it works the same way as Terminal server.
It's a terminal access device, which allow you to share a single PC or server. You can have up to 30 access devices sharing the Same Server OS.
My plan is to use vmware ESXi, and have mutliple virtual machine and connect 15 clients using the ncomputing technologie to eache VM.
The recomandation for a single physical machine is 4 gig ram and quad core processor, and I'm struggling to find out what will be the best recommendation with Vmware Esxi for the CPU.
Will I need one Vcpu per machine ? 4 Vcpu ? and each Vcpu should be assigned to a core ?
Knowing that they will be using Office 2007 or 2010 , Antivirus and Microsoft Steadystate.
Basically, I need to know how much vCPU i will need to have and how many physical core I will need to use per VM in order to get reasonable performance for 15 users using the same VM?
