Just to report my experiences, I have many large volumes with the 
average RW volume being around 7.5GB (it looks like the average volume 
size across all cells is much smaller, say 1GB). I have 6 volumes 
larger than 45G with the largest currently at 205G. Our experience 
suggests that there might be some stability problems with the standard 
inode fileserver (esp. during salvage). We have moved our fileservers 
to namei and used UFS logging (on Solaris 9) and have not seen data 
loss during salvage since. As far as backups go, however, we don't do 
them so I can't comment on that.
