Linux has more HPC code written for it. Solaris is not that big in the HPC market... at least right now... Also, HPC users are just plain used to Linux. Infiniband runs on Solaris, so I'm sure that wasn't the issue.

Nope... Linux is what most people use, and what the *users* know...

Application debugging is a royal pain in the *ss when you have to change compilers/platforms (linux-gcc != solaris-gcc) - best make the transition as easy as possible.
