Discovering and Resolving Back Pressure Issues

Bryan and Adam are joined by members of the Oxide storage team--Josh, Alan, James, and Matt--to talk about Crucible, the service that provides block storage for VM instances running in the Oxide Rack.

In addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues Josh Clulow, Alan Hanson, James MacMahon, and Matt Keeter.

Some of the topics we hit on, in the order that we hit them:

• Hyper-converged infrastructure
• Fibre Channel
• ZFS
• Introduction to Flexible Data Placement: A New Era of Optimized Data Management
• Storage Architecture Considerations
• Ceph
• RFD 60: Storage Architecture Considerations
• RFD 177: Implementation of Data Storage
• RFD 444: Crucible Upstairs Refactoring
• RFD 445: Crucible Upstairs Backpressure
