Citrix VDI-in-a-Box: Sizing Calculator

Using the calculations and assumptions made in the post Citrix VDI-in-a-Box: Sizing Guide I have created the following sizing calculator.

Procedure    

  • Enter total number of users (desktops)
  • Decide on the type of user; Power user or Normal user

Normal user: ~10 IOPS per concurrent user. This user is probably working in a few applications with minimal web browsing.

Power user: ~25 IOPS per concurrent user. This user usually runs multiple applications concurrently and spends considerable time browsing the web.

User definitions taken from “Finding a Better way to estimate IOPS for VDI

  • Enter golden image size
  • Enter number of Golden images you will use
  • Review total hardware requirements

Please note:

  • All assumptions can be edited, therefore you can change the IOPS, RAM or CPU numbers for each setting.  
  • This spread sheet has been published using Microsoft Office Web Apps and therefore might not be available on all platforms.  If demand exists I will look to change that.
  • All calculations use the ROUNDUP fucntion therefore numbers may vary from original post but will provide more accurate if looking at hardware configurations.
