Storage-Specific Challenges

Storage devices are stateful and their throughput can be quite variable, making it challenging to apply the latency-based flow control approaches used in networks. Equilibrium may not be reached if different hosts observe very different latencies during overload. Next we discuss three key issues to highlight the differences between storage and network service times.
