<br>
</div>You do need at least one disk node but performance characteristics of a cluster are highly workload-dependent. If you don't create and remove queues aggressively, disk nodes probably will have the<br>
same performance as RAM nodes (given comparable hardware and OS configuration).<br>
<div class="im"><br>
> I hope my cluster provide good reliability & performance. But from my testing result of question 1, the queue eas gone.<br>
<br>
</div>Are you sure the nodes were clustered? Can you provide a script (or several) that I can use to<br>
reproduce your issue?<br>
<br>
Thanks,<br>
