That graph is taken from a paper we will be publishing as a tech report. Here is the missing text: To show the behavior of the system over time as failures are injected we ran a ZooKeeper service made up of 7 machines. We ran the same saturation benchmark as before, but this time we kept the write percentage at a constant 30\%, which is a conservative ratio of our expected workloads.

I'd like to use the graphic in a presentation, but I'm sure someone will ask these questions. Thanks tons! Stu Hood Architecture Software Developer Mailtrust, a Division of Rackspace
