Comparatif Block Storage

Secure, flexible, on-demand storage volumes.

As your persistent storage requirements increase, you can instantly meet growing demands by hot-adding extra disks to boost the instance’s capacity. These volumes are securely hosted in our clusters, and are ideal for any 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. OVHcloud 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
Prioritizing 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

How to

Create a volume
openstack volume create --type high-speed --size 300 logsdb01

Resize a volume
openstack volume set logdb01 --size 1024

Attach a volume to an instance
openstack server add volume inst01 logdb01

With volumes ranging from 1 GB to 4 TB, you can start small, then scale up as your needs evolve.


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, OVHcloud allows you to easily recover your volume using traditional tools, such as OpenStack's CLI. You can also import a volume to the OVHcloud 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.
