Secure and flexible storage volumes available on demand.
When persistent storage requirements increase, you can instantly meet growing demands by hot-adding extra disks to increase the instance’s capacity. These volumes are securely hosted in our clusters, and can be used to meet the requirements of applications that handle large volumes of data.
Secured by replication
The volumes on each cluster are triple-replicated on three separate disks. Better than a traditional RAID system, the information is distributed on different servers. This ensures the durability of the data in any situation.
Based on Ceph
Ceph is an open-source technology. This allows you to manage demanding, industrial-scale environments, ensuring the scalability of clusters and the reliability of the service. OVH is a partner of the Ceph Foundation, and is investing in the development of this essential building block for OVHcloud.
Our Block Storage range
| Standard | High Speed |
|---|---|
| Prioritising the price-GB ratio, "standard" volumes are ideal for storing large amounts of data without any particular performance requirements. | “High speed” volumes can be used to meet needs where storage must be accompanied by high read and write performance. |
| Triple replication | Triple replication |
| 200 IOPS guaranteed | Up to 3,000 IOPS |

Features
Resizing
With volumes ranging from 1 GB to 4 TB, you can start small, then scale up as your needs evolve.
Backups
Trigger snapshots at any time, to freeze the data status while continuing to use your volume. You can then retrieve your data in its desired state.
Import and export your data
In accordance with our reversibility policy, OVH allows you to easily recover your volume using traditional tools, such as OpenStack's CLI. You can also import a volume to the OVH platform, to use directly on your instances.
Migrating instances
You can hot-add and hot-remove volumes. You can also use a volume to move data from one instance to another, within the same region, almost instantaneously.
Block Storage Billing
Volumes are charged per GB, per hour, depending on the chosen range. The rates shown are for 1 GB, used for a full month.
What SLA does OVHcloud offer for accessing the Block Storage service?
The SLA guarantees 99.9% monthly availability for accessing the Block Storage service. For further information, please refer to the Terms & conditions.
What SLA does OVHcloud offer for data resilience on the Block Storage service?

Can I resize a Block Storage volume?
Yes, you can enlarge a volume. If it is formatted by a file system, you can extend it later.
Can a volume be moved from one region to another?
You can do this by performing an export-import operation that passes through the image catalogue.
Can I migrate from classic to high speed?
You can do this by performing an export-import operation that passes through the image catalogue.
What is the maximum size for a volume?
We recommend not exceeding 4TB per volume.
What locations are available for the Block Storage service?
