The record

Purpose: OpenEBS helps developers and platform SREs deploy Kubernetes stateful workloads requiring fast, reliable container-native storage.
Storage types: OpenEBS turns storage on Kubernetes worker nodes into local or distributed Kubernetes persistent volumes.
Architecture: OpenEBS operates exclusively in userspace, avoiding Linux kernel-dependent software.
Storage engines: OpenEBS v4.6 includes Replicated PV Mayastor, Local PV Hostpath, Local PV LVM, Local PV ZFS, and experimental Local PV Rawfile.
Replication: Replicated Storage can synchronously replicate volumes across Kubernetes zones for high availability.
Snapshots and clones: OpenEBS provides copy-on-write snapshots and clones using Kubernetes-native kubectl operations.
Backup: OpenEBS backup and restore works with Velero through OpenEBS Velero plugins and can target AWS S3, GCP Object Storage, or MinIO.
Observability: OpenEBS volumes expose metrics such as IOPS, throughput, latency, and traffic patterns for Prometheus and Grafana monitoring.
Integrations: OpenEBS documents integrations with Prometheus, Grafana, Alert Manager, ELK, Loki, Logstash, Velero, OpenShift, EKS, DigitalOcean, Rancher, MicroK8s, and KubeSphere.
API: OpenEBS exposes declarative APIs through Kubernetes custom resources.
Security: Replicated PV Mayastor supports TLS for its public REST API, while JWT authentication and internal TLS are listed as planned; plaintext communication is the default.
Installation: OpenEBS can be installed with Helm 3.2 or newer, and the default chart installs Local PV Hostpath, Local PV LVM, Local PV ZFS, and Replicated Storage.
Platform limitation: The OpenEBS kubectl plugin is available for Linux.
Support: DataCore offers OpenEBS support services led by program managers and engineers with Certified Kubernetes Administrator and Developer qualifications.
