VMs per Core – Both Citrix and VMware recommend 7-11 desktops per core being an ideal number for most VDI deployments while maintaining vSphere cluster high availability (N+1) and staying below the maximum supported VMs per core of 16. It is recommendable to leave 10% or more room for CPU bursts. VCPU MHz Overhead – This setting prevents CPU oversubscription. It is recommended 1 vCPU for task users and 2 vCPU for knowledge users.Īverage vCPU MHz – Average CPU utilization per desktop. Number of vCPU – Number of virtual CPUs per desktop. The pre-configured profiles loosely follow LoginVSI 4.1 recommendations. You may also modify a profile after selection according to your needs. User Profile Selection – There are four different user profiles that can be used to configure the desktop type (Task, Office, Knowledge and Power).

VMware's total-cost-of-ownership estimate for deploying VDI to run Windows 7 over four years averaged out to be $2,850 in comparison to total cost of ownership of $4,840 over four years for physical enterprise desktops based on Windows 7. VMware also sought to factor in energy consumption and power costs, which VMware claims its VDI could save as much as $50 on per endpoint on an annual basis. Based on the study VMware did with IDC, storage costs, including configuration, are reckoned to be about $75 per virtual machine. Hug acknowledged that estimating total cost-of-ownership of a VDI deployment is not simple when you take into account how much server and storage and bandwidth may be needed. "This is a grey area for our customers," said Hug. The Microsoft VDA license could end up being $100 per user annually or more or even zero. The Horizon View license can range between $150 to $250 per user, averaging $175 per user. "I've read it 13 times and each time I see a new meaning." He said VDA is roughly $100 per user but several variables come into play, including whether you are using your primary device to access your VDA, or whether it's a smartphone or tablet, which can add an extra $75 per user, he said.
"The most confusing piece is the Microsoft VDA license," Hug said. But in making the argument for VMware Horizon View, he acknowledged the hardest part of coming up with the cost estimate involves Microsoft's licensing of Windows 7 under its Virtual Desktop Access (VDA) plan. "VDI is not cheap but it's cheap when compared to physical desktops," Hug said.
