High Performance: Deliver high-performance storage to both VMs and Kubernetes, ensuring your data is accessible when you need it.
Versatile Integration: Integrate seamlessly with various storage backends, including Ceph, Pure Storage, and more, for maximum flexibility.
Data Security: Keep your data secure with encryption at rest, ensuring your information is protected.
Scalable Storage: Experience storage that grows with your needs, providing a scalable solution for data storage requirements.
Data Redundancy: Ensure the availability of your data with redundant storage, minimizing the risk of data loss.
Automated Backups: Protect your data with automated backups, ensuring your critical information is always safe and can be restored when needed.

Overview

High Integration Compatibility

Provide volume storage to both bare metal and virtual machines through block storage from OpenStack.

Virtual Machine
Cinder is capable of provisioning volume storage for virtual machines using Nova.
Bare Metal
Cinder is capable of provisioning volume storage for bare metal through Ironic.

Reliability

Ceph Compatible

Cinder makes it possible for users to work with Ceph storage backends without complications.

Avoids Backend Limitations
OpenStack’s Cinder enables users to create volumes in Ceph, which provides snapshot management functionality for backing up data stored on block storage volumes that can be restored or used to create new block storage volumes.
Simplifies Code Management
As opposed to manually maintaining a set of codes for each service, users only need to keep one. They can use Cinder for the management of all their provisioning and deleting needs.

Ceph Compatible - No Vendor Lock-In Across the Entire Stack

API

Single API Management

Simplify the management of your storage devices with OpenStack’s block storage.

One Code For All Backends
As opposed to maintaining a different code for each backend, only a single code is needed, as Cinder acts as the holder of all of the codes for creating volumes on different backends.
Integration Made Simple
With each of the backends being within Cinder, users no longer need to create integrations between other services and their backend; they can use Cinder to communicate.

Security

Seamless Encryption

Get the best of both OpenStack’s block storage and key management technologies.

Integrate With Key Management
With Cinder and Key Management, the associated key needs to be pulled down to decrypt its content when a server starts.
Securing Data At Rest
By encrypting your data at rest, it becomes inaccessible to those without the appropriate key, ensuring that your content remains secure, even should someone take the server.
