Block Storage

Block storage that shrugs off failures.

We build highly available block storage on Ceph RBD, replicated across separate failure domains. Attached natively, over NVMe/TCP or iSCSI, for hypervisors, Kubernetes and bare metal.

Features

Replication across failure domains

Data is stored several times on servers in separate failure domains. Losing a server or rack does not lose data.

Performance to measure

Node sizing across CPU, memory, NVMe and network, a dedicated storage network and tuning based on measurements.

Many access paths

Natively via RBD, over NVMe/TCP for hypervisors or classic iSCSI.

Kubernetes integration

Persistent volumes through ceph-csi, with dynamic provisioning and snapshots.

Snapshots and clones

Capture consistent points in time and clone volumes in seconds.

Storage classes

Different profiles for performance, availability and efficiency.

Use cases

01

VM disks

The backbone for OpenStack, Proxmox VE, KubeVirt and other KVM platforms.

02

Persistent volumes

Databases and stateful applications on Kubernetes.

03

Replacing SANs

A scalable successor to traditional SAN systems, without vendor lock-in.
