3. 3
List of file systems
● Disk file systems
(Btrfs,FAT,ext3,ext4,ntfs,ZFS,XFS,HFS,ReiserFS , ...)
● File systems with built-in fault-tolerance
(Btrfs,ZFS,Reliance,HAMMER, …)
● Distributed parallel fault-tolerant file systems
(BeeGFS ,Ceph,Gluster,Google File System (GFS),Hadoop Distributed
File System,XtreemFS , ...)

4. 4
DFS fundamental
● What’s DFS
● Why We should use DFS
● DFS case study
● cons and pros of DFS
● DFS vs SDS
● The future of DFS

5. 5
Distributed parallel fault-tolerant file
systems
● Distributed file systems, which also are parallel and fault tolerant,
stripe and replicate data over multiple servers for high performance
and to maintain data integrity.
● Even if a server fails no data is lost. The file systems are used in
both high-performance computing (HPC) and high-availability
clusters.

6. 6
Type of Storage
● File-level storage
● Block-level storage
● Object storage

7. 7
Advantages of using object storage
● Data model (structured vs unstructured)
● Protocol (NFS,SMB,iSCSI,FC)
● Type of access (locally,remote)
● Access data (server,network,API)
● Caching and meta data mechanism
● Performance and Scability
● Use case (physical,virtual,cloud)
● Real world scenario

8. 8
What is Gluster? (1)
● GlusterFS is a SDS solution for any industry.
● GlusterFS is a scalable network filesystem.
● Using common off-theshelf hardware, you can create large,
distributed storage solutions for media streaming, data analysis,
and other data- and bandwidth-intensive tasks.
● GlusterFS is free and open source software.

9. 9
What is Gluster? (2)
● Scalable, general-purpose storage platform
● POSIX-y Distributed File System
● Object storage (swift)
● Distributed block storage (qemu)
● Flexible storage (libgfapi)
● No Metadata Server
● Heterogeneous Commodity Hardware
● Flexible and Agile Scaling
● Capacity – Petabytes and beyond
● Performance – Thousands of Clients

10. 10
GlusterFS data access overview
● GlusterFS Native Client
● Filesystem in Userspace (FUSE)
● NFS
● Built-in Service, NFS-Ganesha with libgfapi
● SMB/CIFS
● Samba server required (libgfapi based module)
● Gluster For OpenStack (Swift-on-file)
● Object-based access via Swift
● libgfapi flexible abstracted storage
● Integrated with QEMU, Bareos and oth
