Striping Across Four Storage Nodes With GlusterFS On Debian Lenny

This tutorial shows how to do data striping (segmentation of
logically sequential data, such as a single file, so that segments can
be assigned to multiple physical devices in a round-robin fashion and
thus written concurrently) across four single storage servers (running
Debian Lenny) with GlusterFS.
The client system (Debian Lenny 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.
