Updated Character Limits for vSphere Objects

04.22.2021 by William Lam // 2 Comments

I recently saw a question asking about the character limit for the various vSphere Inventory Objects like a Datacenter or Virtual Machine as an example. I was not aware of anything formally documented, but I did come across this 2018 blog post by fellow colleague Todd Simmons, who did some testing with vSphere 6.7 and shared his initial results.


I was curious myself on whether these limits have changed but I also noticed there were many other vSphere Objects that were not tested. I figured this would be an interesting exercise to re-evaluate against the latest vSphere 7.0 Update 2 release and using some PowerShell code like the following to help:

$str = "w" * 80

Below are my findings which have been verified using the vSphere UI and I have also expanded the object list to cover more recent solutions such as vSphere with Tanzu.

    That is nice to know, but regarding limits, we have a problem with ESXi hosts: no more than 280 are allowed in one folder! But we have 400. So we need to build a needles folder structure. Are there any changes in the near future?

    Many thanks for this article - very interesting.
    Did you find any issues where the ESXi host limit is shorter than the vCenter limit?
    For example, if you connect to an ESXi host you can't create a Datastore name with more than 30 characters. If you create one of 50 chars in vCenter is that likely to cause issues when working with the host directly?
    Thanks
