DRBD, developed by LINBIT, is a distributed replicated storage system designed to provide high availability and data protection for small to large enterprises. This solution is aimed at IT professionals, system administrators, DevOps engineers, and cloud service providers who require a reliable and efficient storage solution. It is widely used in industries that rely on high availability clusters and demand seamless data replication.

## Key Features

**DRBD Kernel Driver**: According to the vendor, DRBD is implemented as a kernel driver for the Linux platform. It presents virtual block devices to the system and efficiently mirrors data writes to one or multiple peers.

**Data Plane**: The DRBD kernel driver incorporates a dedicated data path that allows for efficient data transfer without involving user space components, minimizing network traffic. According to the vendor, read requests can be executed locally, reducing the need for network communication.

**DRBD Utilities**: The DRBD utilities include drbdsetup, a low-level tool that interacts with the DRBD kernel driver, drbdmeta, which prepares meta-data on block devices for DRBD, and drbdadm, which processes declarative configuration files and extracts necessary information for the host.

**Network Transport Abstraction**: DRBD provides an abstraction layer for network transport implementations, supporting TCP/IP as the protocol of the Internet, used on top of Ethernet hardware, and RDMA/Verbs, a modern alternative to TCP/IP that aims to enhance performance and reduce CPU load.

**DRBD Windows Driver and Utilities**: The WinDRBD driver for the Windows platform is regularly released with precompiled and signed packages, allowing seamless integration with Windows systems. According to the vendor, comprehensive documentation is available in LINBIT's content hub.

**DRBD RDMA Transport**: According to the vendor, DRBD RDMA Transport takes advantage of RDMA technology to enable the mirroring of data in DRBD setups. It supports multiple paths for bandwidth aggregation and link failover, ensuring efficient data transfer.
