Linux (SuSE enterprise something, possibly with a custom kernel, I’m just a user, not admin) runs just fine on 5.2TB machine, though I can easily imagine you’d have problems if you tried it with, say, DOS :)
The system obviously behaves a bit different from a standard desktop machines, e.g. different areas of RAM are differently fast, depending on the core on which your current process runs, you need to disable individual CPU lines displayed in top etc., but apart from these, mostly everything seems “normal” to me.

this is NUMA, in case anyone 'new to sysadmin' or to architecture is trying to Google this
