LINBIT SDS
What LINBIT SDS is
LINBIT SDS is paid, open-source block storage for private-cloud infrastructure. It combines DRBD replication with LINSTOR orchestration to build resilient clusters on standard hardware, targeting private clouds and high-I/O workloads such as databases. DRBD supports synchronous, asynchronous, and semi-synchronous replication for up to 32 replicated persistent volumes. Storage features include multi-tiering, geo-clustering, thin provisioning, snapshots, clones, automatic recovery, and data-integrity synchronization. Volumes can be accessed through DRBD Diskless, iSCSI, NFS, NVMe-oF, or a Fibre Channel gateway. The product provides a REST API and can ship encrypted snapshots to remote locations. Integrations include Kubernetes, OpenShift, Rancher, OpenStack, Proxmox, and other listed platforms. Supported Linux systems include Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Oracle Linux 6.3+, and Ubuntu Server Edition. Starter begins at $1,000 a year for two nodes.
