I agree completely. If the reference sequence data is split and stored
at each node, then only the query sequences and results (or parsed
results) need to move in and out of the NFS server and across the
network (well, each ref db update moves once). No need to swamp the NFS
or cause massive collisions on your network.

I am interested, has ANYONE used a diskless BLAST cluster?
