Important
OpenEBS provides...
- Stateful persistent Dynamically provisioned storage volumes for Kubernetes
- High Performance NVMe-oF & NVMe/RDMA storage transport optimized for All-Flash Solid State storage media
- Block devices, LVM, ZFS, ext2/ext3/ext4, XFS, BTRFS...and more
- 100% Cloud-Native K8s declarative storage platform
- A cluster-wide vSAN block-mode fabric that provides containers/Pods with HA resilient access to storage across the entire cluster.
- Node local K8s PVs and n-way Replicated K8s PVs
- Deployable On-premise & in-cloud: (AWS EC2/EKS, Google GCP/GKE, Azure VM/AKS, Oracle OCI, IBM/RedHat OpenShift, Civo Cloud, Hetzner Cloud... and more)
- Enterprise Grade data management capabilities such as snapshots, clones, replicated volumes, DiskGroups, Volume Groups, Aggregates, RAID

STANDARD is optimized for NVMe and SSD Flash storage media, and integrates ultra modern cutting-edge high performance storage technologies at its core...
☑️ It uses the High performance SPDK storage stack - (SPDK is an open-source NVMe project initiated by INTEL)
☑️ The hyper modern IO_Uring Linux Kernel Async polling-mode I/O Interface - (fastest kernel I/O mode possible)
☑️ Native abilities for RDMA and Zero-Copy I/O
☑️ NVMe-oF TCP Block storage Hyper-converged data fabric
☑️ Block layer volume replication
☑️ Logical volumes and Diskpool based data managment
☑️ a Native high performance Blobstore
☑️ Native Block layer Thin provisioning
☑️ Native Block layer Snapshots and Clones

- In-cloud: (AWS EC2/EKS, Google GCP/GKE, Azure VM/AKS, Oracle OCI, IBM/RedHat OpenShift, Civo Cloud, Hetzner Cloud... and more)
- On-Premise: Bare Metal, Virtualized Hypervisor infra using VMWare ESXi, KVM/QEMU (K8s KubeVirt), Proxmox
- Deployed as native K8s resources:
Deployments
,Containers
,Services
,Stateful sets
,CRD's
,Sidecars
,Jobs
andBinaries
all on K8s worker nodes. - Runs 100% in K8s userspace. So it's highly portable and run across many OS's & platforms.
NOTE:
Depending on which of the 5 storage engines you choose to deploy, pre-requisites those must be met. See detailed quickstart docs...
- Setup helm repository.
# helm repo add openebs https://openebs.github.io/openebs
# helm repo update
2a. Install the Full OpenEBS helm chart with default values.
- This installs ALL OpenEBS Storage Engines* in the openebs namespace and chart name as openebs:
Local PV Hostpath
,Local PV LVM
,Local PV ZFS
,Replicated PV Mayastor
# helm install openebs --namespace openebs openebs/openebs --create-namespace
2b. To Install just the OpenEBS
Local PV
Storage Engines, use the following command:
# helm install openebs --namespace openebs openebs/openebs --set engines.replicated.mayastor.enabled=false --create-namespace
- To view the chart
# helm ls -n openebs
Output:
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
openebs openebs 1 2024-06-25 09:13:00.903321318 +0000 UTC deployed openebs-4.1.0 4.1.0
- Verify installation
- List the pods in namespace
- Verify StorageClasses
# kubectl get pods -n openebs
