In this session, the speaker presents TopoLVM, a CSI plugin for local storage, and introduces an upcoming Kubernetes feature for local storage that he and his team are working on. Local storage is promising for applications that require high I/O performance, like Elasticsearch and MySQL. TopoLVM provides many features like raw block volumes, resizing, and dynamic provisioning to manage local storage in Kubernetes easily. It also includes a capacity-aware pod scheduling feature that considers each node's local storage capacity. Currently, this capacity-aware feature is achieved by a scheduler extender, which has two main issues: 1. Many admins don't have the right to install scheduler extenders. 2. The scheduler extender is TopoLVM specific. To address these issues, he will introduce a KEP titled "KEP-4049: Storage Capacity Scoring of Nodes for Dynamic Provisioning." to be able to TopoLVM's scheduling logic for all CSI drivers without using scheduler extenders.
