MesosCon EU 2016

Multiple Disk (MESOS-191) is an age old feature request that was implemented at last year's MesosCon EU hackathon. It allows operators to expose multiple disk resources. This enables frameworks to a) utilize more than disk per agent and b) gain exclusive access to a complete disk device (including disk errors when they attempt to exceed the capacity of the volume instead of having Mesos kill the Task when exceeding its disk resource limit).
This talk will give an overview of the different types of disk resources now available (Root, Path, and Mount Disk) and guidelines on when to use which. Secondly we will discuss how multiple disk resources can be utilized by users who are running their workloads using Marathon. Last we will provide best practices for framework developer who are looking for utilizing this feature.

This will be done on the example of the Mesos Quobyte framework which was one of the first frameworks to take advantage of multiple disk support.
