LINBIT keeps Linux systems up and running. As the developers of DRBD® software (, LINBIT has led the way in high availability since 2001. DRBD has been included in the Linux kernel since version 2.6.33 (2009), has been deployed on all major Linux distributions and is fully compatible with systems, applications, devices and services. LINBIT SDS, a high performing Software-Defined Storage (SDS) solution using Linux OS for shared block storage which integrates with the relevant cloud and virtualization systems and thus with OpenNebula. With it common-off-the-shelf hardware is turned into blazingly fast, reliable block storage.

Product Description

LINBIT SDSDRBD provides transparent, real-time replication of block devices without the need for specialty hardware. LINBIT SDS offers with the addon for OpenNebula and the drbd manage middle-ware a seamless integration of the capabilities of Linux’s LVM or ZFS on Linux in combination with DRBD’s replication to Open Nebula. This it leverages on all the features available in these long established and mature open source software components. You can define virtual storage pools for OpenNebula that define the desired redundancy level of your data. The system will spread the instances of the replicated sets evenly over the available storage nodes. Overall this forms a simple scale-out storage solution protecting your data while delivering highest performance. The solutions contains open source components bundled with support from it’s creators.

Product Benefits

DRBD SDS gives you a seamlessly integrated storage solution that relies solely on Open Source software. It offers efficient replication to save against breaking hardware; it offers efficient snapshots to quickly instantiate images; it offers handling of trim/discard for full support of solid state disks; online resize; online verification; online change of redundancy level; online switching between synchronous and asynchronous replication; optional quorum (only with 3 or more replicas); optional fencing

Even More Info

LINBIT SDS contains DRBD and DRBD-Manage. Both software projects are open source software. The whole stack is integrated with adjacent open source software such as the LVM (Linux volume Manager) or ZoL (ZFS on Linux). Development never stays still. DRBD-Manage will be replaced by a better scaling re-implementation called linstor. As soon as that is in place we will enrich it with further features of LINBIT’s product landscape. I.e. optional long distance replication via DRBD-Proxy and optional networking supercharge by native support for RDMA/infiniband-verbs instead of TCP/IP.
