From the GlusterFS documentation:
GlusterFS is an open source, distributed file system capable of scaling to several petabytes (actually, 72 brontobytes!) and handling thousands of clients. GlusterFS clusters together storage building blocks over Infiniband RDMA or TCP/IP interconnect, aggregating disk and memory resources and managing data in a single global namespace. GlusterFS is based on a stackable user space design and can deliver exceptional performance for diverse workloads.
The GlusterFS is a popular filesystem which can be used with Xen Project.
The currently recommended way of employing GlusterFS with Xen Project software is as an iSCSI target. This information comes from discussions with members of the Gluster community. It requires no special drivers in either project as the GlusterFS filesystem will be presented as a standard iSCSI device.
A tighter coupling of the projects would probably be of interest to some members of the Xen Project community. So if you are interested in doing same, let us know.
