you didn't say anything about filesystem size needed and if you are thinking to grow fast
we also run a small cluster ( 20 nodes )
but for climate data modeling results and satellite atmospheric data analysis
we are growing at least 300TB per year (2PB now)
and it's easier for us to grow with lustre
