I currently use CentOS for on my server, and I've been trying to figure out the practical differences between Linux and OpernSolaris. I'm not a linux master, I merely know my way around the system and can generally install things if I need to (though I won't lie, I get tripped up on that sometimes).
If I switch to OpenSolaris, are there going to be major things that I am unable to do now or that at least won't work the same way? My stacks mainly just consist of PHP/MySQL or Node.js/MongoDB.

OpenIndiana/Solaris Pros:
Cons:
Other differences include file system structure, command naming and syntax, etc. There are a few good articles on the difference if you google "linux v opensolaris;" eg: http://linuxhelp.blogspot.com/2009/09/open-solaris-vs-linux-comparison.html, http://tuxradar.com/content/opensolaris-vs-linux
SAMP (solaris, apache, mysql, php) stacks should run just fine, assuming your hardware is all supported.
