“This tutorial shows how to combine four single storage servers
(running Ubuntu 11.10) to one large storage server (distributed
storage) with GlusterFS. 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.“Please note that this kind of storage (distributed storage)
doesn’t provide any high-availability features, as would be the
case with replicated storage.”
