LINBIT Releases WinDRBD 1.0.0 – Bringing High Availability Clusters to Windows Server | News

VIENNA, February 16, 2022 /PRNewswire-PRWeb/ — WinDRBD is the port of the Linux DRBD kernel driver and userspace utilities to the Microsoft Windows family of operating systems. It allows to create high availability (HA) clusters on Windows Server and Client platforms.

WinDRBD provides its storage volumes as normal SCSI disks, which makes it compatible with most Windows applications. As it is a kernel driver, applications such as Microsoft SQL Server and Microsoft Hyper-V can be made highly available in a cluster of Windows nodes.

WinDRBD is compatible with the Linux version, so one can also create mixed setups replicating data between Linux and Windows machines. In addition, WinDRBD allows Windows clients to be booted from one or more Linux servers, thus realizing diskless thin clients running Windows 10 (and in the future Windows 11).


Philippe ReisnerCEO of LINBIT, says, “I am proud and happy that WinDRBD is reaching the 1.0 milestone. This is an important step in the journey. One of the next steps will also bring LINSTOR to the Windows platform.

John Thomas, the developer of WinDRBD explains: “The Linux kernel compatibility layer allows us to use the original Linux DRBD sources inside the Windows NT kernel. With this layer, we can always use the most recent DRBD sources for WinDRBD. It implements kernel mechanisms such as threads, queues, spinlocks, and a network socket API. Therefore, this compatibility layer can also be used to port other drivers from Linux to Windows. Read Johannes mailing list announcement in his original statement here.


LINBIT is the force behind DRBD, the de facto open source standard for high availability (HA) software, and LINSTOR, which manages data storage for enterprise virtualization and cloud computing. LINBIT DRBD software is deployed in millions of mission-critical environments worldwide to provide high availability (HA), geographic clustering for disaster recovery (DR). LINSTOR is the foundation of software-defined storage (SDS) for many cloud orchestration systems such as Kubernetes-based clouds, OpenStack, ApacheCloudStack, OpenNebula, XCP-ng and Proxmox VE.

About WinDRBD:

WinDRBD® is the port of LINBIT’s DRBD kernel driver and userspace utilities to the Microsoft Windows family of operating systems (Windows Server, Windows 10). It is based on the original DRBD source code, which makes it widely compatible with the Linux version of DRBD. Most of the features that come with Linux DRBD are also available on the WinDRBD port. Additionally, WinDRBD can be used to boot a Windows client from a network resource. You can download the exe file here.
