I agree.  I've never understood the "big honking box" syndrom.  It has 
always seemed to me to be an indication of "Pointy Haired Bosses" being 
marketed to that causes this situation.  The point of AFS is speed, 
distribution, and scaleability, but you also get redundancy.  Putting an 
AFS cell on a virtualized server is just IMHO...silly.  I can't see how in 
the long run you save money with specialized boxes when server PCs from 
DELL, which can be used for AFS file servers, cost less than $500 a 
pop.  Of course if you go rack mount, things get more pricey, but still, 
compared to some specialized box from a proprietary vendor?
