I really wished there was some kind of a sizing tool spreadsheet similar to what Microsoft had to offer for their Exchange and OCS/ Lync deployments that make various assumptions to assist you in sizing the a solution. I’ve been trying to work out estimates for a 300 virtual desktop deployment with limited information on the type of OS, remote workers, screen resolution, type of workers, applications to determine stateful or stateless desktops and so forth. What I was able to find was the VMware View Architecture Planning View 4.6 guide (www.vmware.com/pdf/view-46-architecture-planning.pdf) so with it, I worked out a spreadsheet to calculate some numbers:
Unfortunately, the planning guide only provides bandwidth allocation for the knowledge worker so I ended up having to work out some estimates for the other types of workers as well.
With all that being said, I am glad that the planning guide is available and through reading it twice over the last two nights gives me the impression that whoever wrote it put a lot of thought into it. While I do understand that there are seemingly infinite factors that can drastically affect sizing and the best approach is to actually pilot a solution but I still think it would be nice to have some sort of tool that makes a bunch of assumptions and then spits out some numbers with a big footnote saying it’s just to serve as a general guideline.
For those who are used to reading my other posts that are meant to provide a solution to a problem, note that this post is not meant to provide planning guidelines but just a way of speaking my mind towards this exercise. If there’s a tool available for partners that I’m aware about, please feel free to put a comment below to let me know.
