Q: When scaling out horizontally (adding more servers to contain your data), what are problems that arise as you go from, say, 1 commodity server to a few dozen?

The original server, if incorporated into the cluster, is more likely to fail in a given unit of time than if it had been left as a single server.The servers must communicate with one another eating up network bandwidthThe need for redundancy increases as the likelihood of some failure in the system per unit of time increases.Hardware cost per server is likely to increase.
