How DRBD Enables Real-Time Block-Level Replication for High Availability

DRBD (Distributed Replicated Block Device) is a software‑based, network‑driven block replication solution that mirrors disks, partitions, or logical volumes across servers in real time, offering synchronous and asynchronous modes, transparent failover, and a middle‑layer between the filesystem and physical storage.
