[jira] [Created] (MESOS-191) Add support for disk spindles in
resources
Vinod Kone created MESOS-191:
--------------------------------
Summary: Add support for disk spindles in resources
Key: MESOS-191
URL: https://issues.apache.org/jira/browse/MESOS-191
Project: Mesos
Issue Type: New Feature
Reporter: Vinod Kone
It would be nice to schedule mesos tasks with fine-grained disk scheduling. The idea is, a slave with multiple spindles, would specify spindle specific config. Mesos would then include this info in its resource offers to frameworks.

----------------------------------
What do you mean by disk spindles? "a slave with multiple spindles" means "a slave with multiple disks" ?
I share the same idea that mesos tasks should schedule mesos tasks with disk ability,especially for disk bound tasks. But compared to mem/cpu, disk is too compilicated. And it‘s not clear that how could we use IO scheduling strategy when we schedule mesos task. A possible way
is to monitor the IO use rate when schedule mesos tasks. Another way is to use IO isolation to ensure the IO bandwidth for applications.
