One more question. I keep hearing about QoS for volumes as a feature. How will we guarantee service quality for all the bricks from a single server? Even if we weren't doing QoS, we make sure that operations on brick doesn't DOS the others. We already keep hearing from users about self-healing causing problems for the clients. Self-healing, rebalance running simultaneously on multiple volumes in a multiplexed bricks environment would most likely be disastrous.
