  1. Openstack Valence lifecycle management for disaggregated resources

  2. Outline • Challenges of Hyperscale DataCenters • Introduction to RSD and Redfish • Valence • Use cases • Valence features & roadmap

  3. Challenges of hyper-scale data centers • Large number of compute and storage nodes to manage • Hardware updates are cumbersome • Telemetry across large number of nodes • Deployment of software & configuration at scale

  4. What is Rack Scale? • Pooled Resource (network, compute, storage) • Roll in Racks, drop in sleds .. • Agility – via flexible modular architecture

  5. Rack Scale Architectures • Open Compute Platform • EMC / DSSD • HPE Synergy • Intel Rack Scale Design • DriveScale http://www.intel.in/content/www/in/en/architecture-and-technology/rack-scale-design-overview.html

  6. Intel Rack Scale Components • PODM – Pod Manager, spans multiple racks • RMM – Rack Management Module, per rack • PSME – Pooled System Management Engine, one per drawer

  7. A DMTF standard capable of managing multi node servers via a RESTful interface. • A secure, multi-node capable replacement for IPMI-over-LAN. • Add devices over time to cover customer use cases & technology. • Intended to meet Remote Machine Management requirements. • Schema-backed but human-readable http://redfish.dmtf.org/ Introduction to Redfish

  8. The Redfish API • The Service Root is the top level document • GET http:///redfish/v1 • From Service Root, one can reach the rest of the resources • Chassis – Systems – Manager – Registries – Account Service – Event Service – Session Service – Task Service • Redfish API for composing a node: POST /rest/v1/Nodes/Actions/Allocate

  9. Companies Involved

  10. Valence & Current Features • Life cycle manager for disaggregated systems • DMTF Redfish support • H/w life cycle management • Node composition • Composition flavors • Register with provisioning tool • Delete composed node

  11. Valence & Current Features • Provide support for multiple-Podm • Provide support for multiple clouds • Valence Flavors • Integrate with provisioning/deployment tools - Ironic

  12. Valence - Demo

  13. Use cases of RSD and Valence • Ericsson HDS 8000 • Dell EMC DSS 9000 • Lenovo XClarity PODM

  14. Use cases : Relations between valence PODM DCs • Split DataCenter into different Pod Managers if necessary • Integrate different vendors of RSD instances (PODM) • Different usage scope of the PODM • PODM monitoring

  15. Ericsson HDS 8000

  16. Dell EMC DSS 9000 • Cover different workload requirement • Open management via Redfish + RSD • HW → pool resources • Maximum flexibility

  17. Lenovo XClairty PodManager • Valence Podmanager scheduler • ComposedNode with NVMF & GPU • Deployment • Deliver by Remote Controls

  18. Road Map & Future • Full support for integration with provisioning tools （ironic ...） • Multi Cloud support （OpenStack，AWS，Azure ...） • Support for enhanced telemetry • Fix the gap and build a connector between HW and SW
