Highly Available Replicated Disk Drives for Windows
WinDRBD® brings the power of DRBD® to the Windows world. WinDRBD is built on and tracks changes with the original time-tested, enterprise-ready DRBD for Linux engine. WinDRBD is a perfect fit for highly available Microsoft SQL Server, Hyper-V or Windows file server deployments.
LINBIT Software-Defined Storage (SDS) for Windows
LINBIT® has ported its Linux-based HA stack to Windows (Server 2016, 2019, 2022, 2025, Windows 10, 11), including:
- WinDRBD: A native Windows kernel driver based on DRBD that provides highly available virtual disks to applications and file systems
- LINSTOR For Windows: A software-defined storage (SDS) solution for managing DRBD and WinDRBD resources
Optional features include cross-platform Windows/Linux replication, DR with DRBD Proxy, and a web-based GUI for easy cluster management.

Architecture
WinDRBD is the port of the LINBIT-developed DRBD kernel driver and userspace utilities to the Microsoft Windows family of operating systems. (Server 2016, 2019, 2022, 2025, Windows 10, 11). It is based on the original source code of DRBD, which makes it widely compatible with the Linux version of DRBD. Most features that come with Linux DRBD are also available in the WinDRBD port.
