Prototyping Innovative Data Storage
Storage Area Networks
Distributed Data Storage
Ceph 
is a distributed file system designed for reliability, scalability, and performance. The storage system consists of some (potentially large) number of storage servers (bricks), a smaller set of metadata server daemons, and a few monitor daemons for managing cluster membership and state.
XTREEMFS
is a distributed and replicated file system for the Internet. Distributed: Clients and servers can be distributed world-wide.
XtreemFS allows you to mount and access your files via the internet from anywhere.
With both Ceph and XtreemFS you can easily replicate your files across multiple devices this reducing network consumption and latency and increasing data availability.
