Edoceo offers consulting services for High Availability Linux systems.
GlusterFS is an excellent method to create a distributed replicated file system for high availability. By exposing parts of an individual host's file system as a brick data can be replicated across the room or across the globe. GlusterFS is initially complicated but after a few rounds through the volfile GlusterFS become much simpler to understand. We offer consulting services for this package strictly on an hourly basis with a four hour minimum commit.
