OpenEBS is a Persistent block-mode Data Storage platform with an native vSAN fabric; for Kubernetes. We are CNCF member project. We are the largest global community of K8s storage users.

Our project team was an early pioneering inventor of K8s Container Native Storage services (we invented the term). We conceived the vision of a Stateful Persistent data platform for K8s that is tightly integrated and natively embeded into the core of K8s.

We built an innovative High-performance Enterprise grade Block-mode Hyper-converged Storage vSAN Fabric that augments the storage services of K8s with Stateful Persistence, Enterprise Data mgmt, SSD/NVMe optimized I/O services, Replicated Data volumes, Thin Provisioning, Snapshot, Clones; and many other Mission critical data storage services that don't come in K8s out-of-the-box.

OpenEBS is very popular :
Live OpenEBS systems actively report back product telemetry each day, to our Global Analytics system (unless disabled by the user).
Below are our project popularity & pentration metrics as of: 01 May 2024

🚀   OpenEBS is the #1 deployed Storage Platform for Kubernetes
⭐   We are the #1 GitHub Star ranked K8s Data Storage platform
💾   We have +49 Million Volumes deployed globally
📺   We have +9 Million Global installations
⚡   1 Million OpenEBS K8s Containers are spawned per week
😎   1.7 Million global users

	Building a K8s Enterprise Data Storage platform is complex, and areas of the Data & I/O stack could be considerd 'Storage Rocket science'. Our global team comes from many areas of the data storage industry. Companies like... Microsoft Azure, VMware, DELL/EMC, Brocade/Broadcom, Hitachi Vantara, INTEL, Nvidia/Mellanox, IBM, RedHat and DataCore.

STANDARD (Open Source Standard) is our Ultra modern Datastore stack that is strongly aligned with the cutting edge direction of storage use-cases in the K8s industry. It is designed to facilitate modern K8s datastore architectures, key K8s I/O patterns, K8s data access methods, K8s data use-cases and where K8s Datastore applications are heading.

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

LEGACY consists of Data-Engines that we experimented with early on. These Data-Engines have a number of open-source
technologies embedded inside them, and are a great intro into the world of simple K8s storage services. LEGACY helped
us learn, iterate and develop our core storage K8s strategy, as well as discern how users want & need to interact with
K8s storage services. LEGACY also helped to reveal key areas within K8s that are lacking in storage/datastore services,
what areas of K8s we could optimize; and how we can provide the best value into the various K8s storage layers.

There are multiple Data-Engines within LEGACY:

Our 2024 Roadmap is here It defines a rich set of new features that are planned for 2024.
Please review this roadmap and feel free to pass back any feedback on it, as well as recommend and suggest new ideas. We welcome all of your feedback.

OpenEBS is the most successful Stateful Persistent Container Native Storage platform in the CNCF landscape. It has always held the #1 position and continues to as of today.
