I've seen a lot of different approaches for people trying to build their own at that scale (taking off of a bus and storing for medium-long term analysis), so I'll share some data re: what I've seen (not specific to vFlow).
Nice analysis of the current state of the art.
And then, the biggest flow store I know of (1 or 2 carriers may want to argue but I haven't seen theirs) is at DISA for DoD - > a decade of un-sampled flow coming from SiLK. All stored in hourly un-indexed files, essentially nothing but CLI to access,
FlowViewer provides a web GUI for invoking SiLK analysis tools. Provides textual and graphical analysis with the ability to track filtered subsets over time. Screenshots, etc.: https://sourceforge.net/projects/flowviewer/ Joe
