Assume you mean hardware-wise.

For software, I'd run Ubuntu-creamsicle with Ruby on Grilled Peaches on top.

But seriously, there's a thread 6 mos back about the cost of building a 
NAS device but with smaller storage.  The cost dropped dramatically over 
the years, except now when it comes to hard drive costs, of course.

For a data store that size, I would look to keep it on multiple nodes 
from the start, but especially if you'd have to scale later on.

Software-wise, the easy way is to go with FreeNAS.  They make it *very* 
easy.  And there's support for fibre channel and Infiniband.  And 
certainly ZFS at that scale.

Run it off a cf card and you should be happy to your heart's delight.
