purpose scale-out distributed file- system supporting thousands of
clients Aggregates storage exports over network interconnect to
provide a single unified namespace File-system completely in
userspace, runs on commodity hardware Layered on disk file systems
that support extended attributes

available disks and storage devices Create new bricks by creating
new Logical Volumes (Thin LVs) Format the logical volume with the

15. 06/26/15 15Fudcon Pune 2015 Gluster Snapshot Supports
Volume Snapshot related operations Snapshot configurations at
Volume level as well as Cluster level Supports Snapshot scheduling
to take repeated snapshots based on the time interval
16. 06/26/15 16Fudcon Pune 2015 Geo Replication Enables
creation and maintenance of Geo- Replication sessions across
clusters http://www.ovirt.org/Features/Gluster_Geo_Replication
17. 06/26/15 17Fudcon Pune 2015 Storage Network Selection
Currently, Gluster nodes use the same network for both Management
and Gluster traffic (possibly causing traffic chokes) The proposed
solution is to separate out the GlusterFS traffic and management
traffic VMsandStorageEngine Direct-attached storage (SAS/SATA)
