Obligatory “Solaris just works” comment: at Boeing I was lucky enough to be in a position to watch our IT standards (and the contents of our data centers) shift over the course of the 2000s. When I first started (back in the old OG CoG days—my first day at Boeing was September 10, 2001) our Houston datacenter had tons (literally) of DEC Alphas running Tru64, tons of HP-UX racks, tons of IBM Z-series gear, and tons of giant purple Sun SPARC cabinets. The only Windows servers were domain controllers, a file server or two, and the Exchange servers.
Over the course of the decade most of the non-Windows gear was slowly EOL’d and replaced by commodity Dell and HPaq servers, and when I left Boeing in 2010 Windows Server was the standardized platform for basically everything…
Because it turns out that even in 2010, Solaris was still the only platform that could run NetBackup at massive scale (think >1PB under management in just our local DC) without puking all over itself and falling down. We experimented with NBU under Windows and it was like trying to troubleshoot an in-progress nuclear explosion.
So I’d say that you’ve got some solid hardware and software to play with, @moufassa—though you might consider checking out whether you can use Illumos on it. The Illumos project is where all the smart people who originally worked on Solaris are now, since almost all of them quit when Oracle acquired and destroyed Sun.
(And if you’d like to know why they all left, I direct you to this video, which contains at the linked time of 33 minutes possibly one of the greatest rants—aimed at Oracle in general and Larry Ellison specifically—that I have ever heard in my life.
