Assume that each node is PXE booted, has bonded 10G NICs and gets / puts data into a DFS. Nodes would be maxed out on RAM to reduce swapping. </p> <p>Seems like this would have the advantages of:<br /> 1) less power consumption<br /> 2) easy to replace failed nodes<br /> 3) easy to add new nodes / grow array<br /> 4) lower cost / node</p> <p>Disadvantages:<br /> 1) slower disk IO speed<br /> 2) ??</p> <p>What *huge* *horrible* *are you crazy* things am I missing? </p>
