Alta disponibilidad usando DRBD (Distributed Replicated Block Device) en Linux

Nos mandan un artículo de como utilizar en Linux una nueva característica llamada DRBD (Distributed Replicated Block Device), que permite copiar bloques de información por red y crear esquemas de fail-over:

The 2.6.33 Linux kernel has introduced a useful new service called the DRBD – Distributed Replicated Block Device. This service mirrors an entire block device to another networked host during run time, permitting the development of high-availability clusters for block data. Explore the ideas behind the DRBD and its implementation in the Linux kernel.

Lo interesante aquí es hacer un cluster de alto disponibilidad con servidores remotos o regionales unidos mediante enlaces de fibra óptica por si alguna región queda inacesible los sistemas se encontrarán funcionando.
