The S3 Server Hackathon focuses on Scality's object-based software-defined storage solution, designed for high performance and reliability using standard x86 servers. Participants will present their innovative projects, with criteria centered on functionality, market potential, and execution, alongside insights into the Scality S3 server and Seagate Kinetic drives. The event features team assignments, a presentation agenda, and an emphasis on open-source development.

2. Welcome to the
S3 Server Hackathon!

Scality RING: Automatize storage for Digital Business
The Scality RING
is object-based
software-defined
storage for the cloud.
We run on standard
x86 servers and
create a giant pool
of storage.
We protect the
data and provide
100% reliable, high
performance access
for any capacity-driven
application.

Agenda for today
Presentation of the hackathon, judges and logistics
S3 Server tech Overview - https://github.com/scality/s3
Seagate Kinetic drives Overview
Teams and projects assignement!

5. The Judges!

6. The Prizes!

7. How are we judging?
We know the code will not be beautiful!
We’re looking for a functional prototype
It’s OK not to handle quirky corner cases!

8. How are we judging?
Innovation - We’re looking for creative solutions
Market potential - It has to solve a real problem!
Execution - A working demo ☺

9. Each team has:
A name,
A mentor,
A clear defined project that’s achievable,
Developers and a leader,
Each team will do a 5 minutes pitch + demo on Sunday

10. Logistics!

12. Open source S3 Server!

13. S3 Adoption keeps rising

14. © Scality 201614
▪ Open source object storage server
https://github.com/scality/s3
▪ Written in Node.js
▪ Single instance running in a docker
container
▪ Uses docker volumes for persistent storage
▪ Same code as Scality’s RING S3 interface
What is S3 Server?

15. © Scality 201615
▪ Developers can install
and develop
S3-based apps locally
▪ Enterprises can host
a local test/dev
environment to learn
about object storage
▪ Enterprises can host
a small, local object
storage system in
production

19. Seagate Kinetic
Kinetic development and the basics

20. Kinetic On SMR (Shingled Magnetic Recording)
What is Kinetic
Kinetic is a drive architecture in which the drive is a key/value service with Ethernet connectivity
Put/Get/Delete API over TCP/SSL
https://www.openkinetic.org/
SMR
Data recording technology used in drives to increase storage density and overall storage capacity
https://en.wikipedia.org/wiki/Shingled_magnetic_recording
Why Kinetic on SMR
Increase storage capacity
Same Put/Get/Delete API (SMR is transparent to users/applications)

21. Kinetic Development Overview
Kinetic Simulator
Functionally equivalent to Kinetic Drives.
https://github.com/Kinetic/kinetic-java
Build
git clone https://github.com/Kinetic/kinetic-java.git
mvn clean package
Run (one or more instances)
java -jar kinetic-simulator/target/kinetic-simulator-"Version"-SNAPSHOT-jar-with-dependencies.jar or
./bin/startSimulator.sh
More Information Related to Build
https://github.com/Kinetic/kinetic-java/blob/master/README.md
Preferred IDE: Eclipse (Mars and up)
http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/neon1a

22. Notes On Kinetic K/V Keys
Keys are sorted lexicographically. e.g.
http://google.github.io/guava/releases/snapshot/api/docs/com/google/common/primitives/
UnsignedBytes.html#lexicographicalComparator%28%29
https://github.com/Kinetic/kinetic-java/blob/master/kinetic-simulator/src/main/java/com/se
agate/kinetic/simulator/persist/leveldb/KineticComparator.java
Use sequential keys for better throughput (not required for later releases)
An example to generate sequential keys
https://github.com/Kinetic/kinetic-java/blob/master/kinetic-test/src/test/java/com/seagate/ki
netic/KVGenerator.java

23. Hackathon Group Key Space
Each group is recommended to use its own assigned key space (prefix) to avoid
conflict for shared drives. For example, group 1 is assigned prefix of “00”, group 2
is assigned prefix of “01”., etc. Eg:
All keys in group 1 would be in the form of “000”, “001”, “002” ..., etc.
All keys in group 2 would be in the form of “010”, “011”, “012” ..., etc.
All keys in group 3 would be in the form of “020”, “021”, “022” ..., etc.
