Outline ● Challenges of Hyperscale Data. Centers ● Introduction to RSD and Redfish ● Valence ● Use cases ● Valence features & roadmap

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

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

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

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

Introduction to Redfish ● ● ● 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/

The Redfish API The Service Root is the top level document GET http: ///redfish/v 1 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/v 1/Nodes/Actions/Allocate

Companies Involved

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

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

Valence - Demo

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

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

Ericsson HDS 8000

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

Lenovo XClairty Pod. Manager ● Valence Podmanager scheduler ● Composed. Node with NVMF & GPU ● Deployment ● Deliver by Remote Controls

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