“This tutorial shows how to set up a high-availability storage
with two storage servers (Ubuntu 11.10) that use GlusterFS. Each
storage server will be a mirror of the other storage server, and
files will be replicated automatically across both storage servers.
The client system (Ubuntu 11.10 as well) will be able to access the
storage as if it was a local filesystem. GlusterFS is a clustered
file-system capable of scaling to several peta-bytes. It aggregates
various storage bricks over Infiniband RDMA or TCP/IP interconnect
into one large parallel network file system. Storage bricks can be
made of any commodity hardware such as x86_64 servers with SATA-II
RAID and Infiniband HBA.”
