1. STANDARD ✔️ > Ready Player 1
2. LEGACY ⚠️ Game Over

Within STANDARD, you have a choice of 2 Types of K8s Storage Services. Replicated PV and Local PV.

Type	Storage Engine	Type of data services	Status	In OSS ver
Replicated_PV		Replicated data volumes (in a Cluster wide vSAN block mode fabric)
	Mayastor	for High Availability deploymemnts distributing & replicating volumes across the cluster	Stable, deployable in PROD	v4.0.1
Local PV		Non-replicated node local data volumes	(Local-PV has multiple variants. See below)	v4.0.1
	Local PV HostPath	for integration with local node hostpath (e.g. /mnt/fs1)	Stable, deployable in PROD	v4.0.1
	Local PV ZFS	for integration with local ZFS storage deployments	Stable, deployable in PROD	v4.0.1
	Local PV LVM	for integration with local LVM2 storage deployments	Stable, deployable in PROD	v4.0.1
	Local PV Rawfile	for integration with Loop mounted Raw device-file filesystem	Stable, deployable in PROD, undergoing evaluation & integration release: v0.70	v4.0.1

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, Virtualzied Hypervisor infra using VMWare ESXi, KVM/QEMU (K8s KubeVirt), Proxmox
• Deployed as native K8s elemets: Deployments, Containers, Servcies, Stateful sets, CRD's, Sidecars, Jobs and Binaries all on K8s worker nodes.
• Runs 100% in K8s userspace. So it's highly portable and run across many OS's & platforms.

• Replciated PV Mayastor Roadmap

NOTE: Depending on which of the 5 storage engines you choose to deploy, pre-requests that must be met. See detailed quickstart docs...

1. 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 Mayastor

# helm install openebs --namespace openebs openebs/openebs --create-namespace

2b. To Install just the OpenEBS Replicated Mayastor Storage Engine, use the following command:

# helm install openebs --namespace openebs openebs/openebs --set engines.replicated.mayastor.enabled=false --create-namespace

3. To view the chart

# helm ls -n openebs

Output:
NAME     NAMESPACE   REVISION  UPDATED                                   STATUS     CHART           APP VERSION
openebs  openebs     1         2024-03-25 09:13:00.903321318 +0000 UTC   deployed   openebs-4.0.1   4.0.1

4. Verify installation
   • List the pods in namespace
   • Verify StorageClasses

# kubectl get pods -n openebs
