Fig. 2. The two-sites based provisioning of the GARRbox cloud storage service
Aggregation Layer
The aggregation layer is provided by GlusterFS deployed at two sites, GARR Headquarters in
Rome and University of Milano Bicocca.
GlusterFS has been deployed and configured creating distributed and replicated type gluster
volumes in both the Rome and Milano sites. Each cluster exports via GlusterFS to the
corresponding front-end node 2 GlusterFS volumes : one acting as the main reposistory for
users accessing the corresponding GARRbox front-end, and a second one, currently used for
GlusterFS cross-replication between the Rome and Milan sites.
The system is therefore exploiting GlusterFS geo-replication of distributed and replicated
Volumes between the two sites.
A detailed layout of the GARRbox layered architecture is shown in Fig.3.
