Storage that grows with you

Block storage for growing workloads

Volumes separate data from the server: storage can be scaled independently of the CPU and RAM – ideal for databases, file storage and growing applications.

Flexibly scalable

Expand volumes whilst the system is running, reassign them to other VMs, or run multiple volumes per server – whatever suits your needs.

A high-performance foundation

NVMe-based block storage delivers the IOPS required by databases, search indexes and I/O-intensive applications.

Snapshot integration

Back up volume states in seconds using snapshots – as a basis for backups, clones or risk-free updates.

Stored securely

Redundant storage and encryption in certified to ISO 27001 on the basis of IT-Grundschutz German data centres – GDPR-compliant.

Data and computing decoupled

The storage layer of your cloud architecture

Combine volumes with ccloud³ VMs for databases and application data, use snapshots for consistent backup points and S3 Object Storage for archives – this creates a storage architecture that keeps pace with every stage of growth.

Block Storage – An Overview of Prices

How much does block storage cost at centron?

Block storage costs €0.05 per GB per month with centron – a 100 GB volume therefore costs €5.00, and a terabyte costs €50.00. The volumes run on NVMe hardware, can be expanded whilst the system is running, and can be moved between virtual machines without the need to copy data. This allows you to separate system data from user data and scale both independently of one another. Volumes have a 99.9% availability rate and are hosted in certified to ISO 27001 on the basis of IT-Grundschutz data centres in Germany.

Volumes FAQ

Everything you need to know about volumes

What are volumes?

Business-ready block storage that you can create, attach and scale independently of your ccloud³ VMs. Volumes behave like additional hard drives – with NVMe performance and flexible sizing. The Cloud Storage Guide explains when block storage and when object storage is the right choice.

Can I increase the size of a volume at a later date?

Yes, whilst the system is running and without any migration: extend the volume, adjust the file system, and you’re done. This way, your storage grows along with your data, without the need to resize the VM.

What happens to my data when I delete the VM?

Volumes are decoupled from the VM’s lifecycle: the data is retained and can be attached to a new or different VM – ideal for fresh installs and migrations.

How do I back up volumes?

With Snapshot, you can back up the state of a volume in seconds – for example, before updates. For regular, automated backups, combine volumes with cBacks.

How much do volumes cost?

Billing is based on the capacity booked. You can calculate your exact costs transparently using the price calculator – new accounts receive a €200 starting credit.
