How many physical servers can vSphere 5.5 be installed on?

[BradShows]

I have a license key for vSphere 5 Enterprise Plus.  It has a license for 2 CPUs. I have it installed on a single physical server now.  I would like to find out if I can install it on one or more servers utilizing the same key.  

Thank you.

First point is that 5.5 is end of life, it is no longer supported or updated.

To answer your question though, if your single physical server has 2 CPUs then you’ve already used up the licenses you own and should not be installing ESXi on any other hardware without purchasing more licenses.

As Scott, says, it depends on how many licenses you are using right now. But, 5x is out of support. you should seriously consider upgrading.
