Openstack Valence Project
Overview
Valence is a service for lifecycle management of pooled bare-metal hardware infrastructure. The concept of pooled storage (SSDs or nvmE) disaggregated from compute nodes and network disaggregated from compute and storage provides the flexibility to compose and uses as and when the cloud requires more server resources. Valence provides the capability "compose" hardware nodes and release resources as needed by the overcloud.
Valence supports Redfish as default management protocol to communicate to hardware. It supports Rack Scale Design (RSD), Open architecture for management of disaggregated server hardware resources, which is standardized in Redfish. Valence also provides capability to manage other vendors disaggregated hardware using their respective drivers other than Redfish.

Feature Highlights
Valence provides the following capabilities for managing disaggregated hardware resources.
Multiple Podmanager Support
Valence provides the capability to manage multiple podmanagers. Each
podmanager can be configured to use different driver. By default,
redfishv1 driver is used.
- Currently supported drivers in Valence are:
-
redfishv1-driverexpether-driver
Future work include redfish v2 driver support. Other vendors also could implement their own driver to manage their hardware.
This provides uniform interface to manage all the disaggregated hardware in datacentre supporting different protocols.
Device Orchestration framework
Valence provides support for the dynamic management of pooled resources like storage, network and other pci devices which can be connected on demand to a composed node, giving user the ability to attach or detach the devices dynamically based on workload.
Ironic provision driver
Valence supports ironic provision driver to be able to
register the valence composed node to ironic. Once the node is
registered further operations of provisioning/managing could be directly
performed using Ironic.
For more details on Ironic usage: Ironic API guide.
For more features please refer the Valence blueprints for supported and in-the-pipeline features.
