Block Storage

Flexible and efficient storage for demanding workloads.

Ultra resilient

Data is replicated three times, guaranteeing 99.99% availability to all our customers, even in case of a disk failure.

Flexible vertical scaling

Scale up to 10TB storage capacity with no downtime to adapt to changes. Attach or detach Block Storage volumes without having to reboot your Instances.

Easy setup and migration

Create a Block Storage volume in seconds using our console, CLI, API or Terraform provider. Easily move your data from one Instance to another by detaching and then reattaching your volumes without any downtime.

Block Storage use cases

Save data after Instance or cluster deletion. Ideal for quickly accessible and easily transferable data and backups. Kubernetes Kapsule automatically uses Block Storage when you create persistent volumes.

As databases require a lot of IOPS, Block Storage is perfect for storing them. You can also increase your volumes as your project grows with hot resize to accommodate a frequently fluctuating application workload.

Expand the storage space up to 10TB on your Instances for larger production when you exceed the capacity of your local volume. Each block volume is then accessible as a local drive.

Frequently asked questions

The size of local storage depends on your Instance type. With today’s configurations, the maximum local storage available is 600GB. Block Storage allows you to create bigger volumes and these volumes are persistent which means that they can live without being attached to an Instance.

Block Storage offers 5,000 input/output operations per second (IOPS) through powerful SSDs. This guarantees 99.99% availability to all our customers. However, this performance is subject to fluctuation during peak load periods.

A block volume is persistent which means that it can live without being attached to an Instance. Nevertheless, the following can be expected:

  • When the Instance is deleted via the Scaleway console, you will be asked if you want the distant block volumes to be deleted as well or not;
  • When the Instance is deleted via API, all the attached volumes are deleted as well which include the block volumes.
