Techopedia Explains I/O Spikes
One of the common scenarios where I/O spikes are a problem is in a network or system with a storage area network. Here, stored data are distributed across a range of containers and are available to multiple servers. What happens with this and other kinds of distributed networks is that high demands on data require a lot of server activity, and if a lot of this activity happens at once, it produces I/O spikes.
