OpenStack Cinder review
A broad, driver-based block-storage service for self-hosted OpenStack clouds.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenStack Cinder is the Block Storage service for creating and managing persistent volumes across Nova virtual machines, Ironic bare-metal hosts, containers, and other workloads. It suits teams operating OpenStack private clouds that need block-storage lifecycle management through a REST API, Horizon, or OpenStack command-line clients. As open-source, self-hosted infrastructure software, Cinder is aimed at operators who manage the surrounding OpenStack and storage environment rather than buyers seeking a hosted storage product.
Its strongest fit is the OpenStack ecosystem. Cinder integrates with Nova for virtual-machine storage, Horizon for web-based management, Keystone for identity, and Barbican for key management. The service supports default and custom volume types, snapshots, backups to a backup storage provider, encryption of volume data at rest, and attachment to multiple hosts when the back end supports it. Pluggable drivers connect deployments to storage systems including LVM, Ceph, NFS, iSCSI, and vendor systems.
Cinder covers a wide range of block-storage operations, but its practical behavior depends on configuration. Capacity, supported volume features, performance limits, replication, and failover vary by storage driver and deployment. Multi-attach is available when supported by the back end, while replication and failover are driver-dependent capabilities. Choose Cinder when OpenStack integration, self-hosting, and storage-back-end flexibility matter; consider a different option if you need a vendor-hosted service with standardized operational limits and a managed storage experience.
