GlusterFS is an open source, scale-out network filesystem. It runs on commodity hardware and allows indefinite growth in capacity and performance by simply adding server nodes. Key benefits include flexibility to deploy on any hardware, linearly scalable performance, and superior storage economics compared to traditional storage solutions. GlusterFS uses a distributed hashing technique instead of a metadata server to provide high availability and reliability.

4. History of Gluster
How it all started
– Backgrounds in high performance, clustered computing
– Working at Lawrence Livermore National Labs
• AB Periasamy & Hitesh Chellani design “Thunder”
• One of the worlds fastest super computers
• On Intel commodity hardware
• Solved filesystem scalability and performance limitations
– Large customer in oil & gas persuaded them to focus on storage
– Gluster founded by Hitesh & AB to bring technology to market
Thunder
Result: award winning technology

9. Software Only
Hardware agnostic
Superior storage economics & flexibility
– Data center / private cloud use commodity hardware
– Public cloud – i.e. AWS, RackSpace, GoGrid – pay for only what you need
No lock-in
– Hardware vendors-at purchase time or in the future
– Public or private cloud
– Performance, capacity, or availability levels
– GlusterFS – not proprietary, files are stored in native formats (i.e. EXT4)

12. Elastic Hashing
No metadata server
An algorithmic approach
– Unique hash tag for each file stored
– Tags stored within the file system
– Rapid file read – low latency
