“If you lose one server from replication1 and one from
replication2, the distributed volume continues to work. 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.”
