VDI Calculator v7 Now Available w/ major changes

Today I am releasing a new version on my VDI calculator, V7. This is a major release that include major improvements to the way VDI infrastructures are calculated, while also simplifying the process for people new to VDI sizing. I put a lot of effort into this release and had to make some big code changes to accommodate the desired outcomes. Let’s go to What’s New!

 

  • Pre-Defined User Profiles (red) – The calculator now offers 4 pre-configured user profiles to be selected from (Task, Office, Knowledge and Power). These profiles have different characteristics, such as CPU, IOPs and Memory, and they follow LoginVSI 4.1 workload definitions for the most part. These user profiles may be individually selected for each distinct desktop pool type; eq. a deployment could have 3 desktop pool with each one having a different user profile assigned. The profile may also be modified by the user upon selection for additional customization.

  • VMs per Core is now a Desktop Type choice (blue) – This is probably the major change to the way the calculator works. Until this release the number of desktops (VMs) per pCPU core was always a selection done for all desktops in a Desktop Pools and for all servers. As we know, this is not how we implement VDI, because each distinct desktop pool has normally different desktop configuration with different resource allocation. Therefore they will each commonly have a different number of desktops per pCPU core. In this release this choice can be done per desktop pool or desktop type.

 

  • Linux Support – In addition to Windows and OSX, the calculator now also runs on Linux. (Tested on Ubuntu 14.04)

 

  • Display Numbers and Resolution (Video vRAM Update) – Each virtual desktop has an associated memory and CPU overhead according to the size of the vRAM selection; a combination between Display Numbers and Resolution. The calculator is not using the new numbers provided by VMware for Horizon View 7 with PCoIP. While there may be differences between Horizon View and XenDesktop, PCoIP and ICA, or vSphere and Hyper-V, the differences in terms of percentage of resource utilization doesn’t change much for the large majority of deployments.

  • New Default Values – Some default values have been modified to a more realistic and up-to-date scenarios. This include the Number of Cores per Socket = 12.

 

  • How-to-Use Guide – The How-to-Use guide has been updated to include all the recent changes and a FAQ section has also been included. Access the guide here.

    Can you add in GPU options with NVIDIA? And maybe add in Designer too at the very top end? Great tool though!

    Rochard, I am not sure from a sizing perspective, besides VM memory and CPU, there would be many changes to the configuration. Any insights? BTW – thanks for the feedback,
