I thought the OP was asking: If I have one physical server with 6 drives in it, would it be better to run a single chunkserver process and give it all six drives or run 6 chunkserver processes giving them 1 drive each. Even if the OP wasn't asking it this way, it'd still be nice to know the answer with regards to performance. :) Elliot |
