1. GSICS 2015 GDWG Breakout Session 1 GSICS Collaboration Servers Peter Miu EUMETSAT CMA, CNES, EUMETSAT, ISRO, IMD, JMA, KMA, NASA, NIST, NOAA, ROSHYDROMET, USGS, WMO

2. GSICS 2015 GDWG Breakout Session Overview  The fundamental operations behind the GSICS collaboration server network are:  Collaboration network should inherently have:  Redundancy  Some Backup  Regional “faster” access 2 OperationCMAEUMNOAA Data Exchange: Source Data Exchange: Intermediate Data Preservation: Intermediate Data Archiving: Intermediate Data Upload: GSICS Products Data Preservation: GSICS Products

3. GSICS 2015 GDWG Breakout Session 3 Data Management Servers  Collaboration Server Network Status: 3 OperationCMAEUMNOAA Source Data Availability Intermediate Data Availability GSICS Products

4. GSICS 2015 GDWG Breakout Session To discuss  Configuration Updates  Data Preservation (later)  Operations Tasks  Product Development Tasks  Server Level Agreements for Operations  Point of Contacts 4

5. GSICS 2015 GDWG Breakout Session Data Preservation  Data Preservation (DP) means reliable access to the data.  Collaboration network shall DP – endorsed by EP 2015.  Collaboration network context; replication of GSICS products.  Concept is similar to the Hadoop Distributed File System (HDFS)  Data is uploaded 1 server  Data automatically replicated on all collaboration servers 5

6. GSICS 2015 GDWG Breakout Session Data Preservation Constraints Encountered  File Sizes – Define Limitation  Transfer Speeds - Limitation  Security – To Overcome  Development Resources  Financial Resources 6

7. GSICS 2015 GDWG Breakout Session Data Preservation Prototype  EUMETSAT has developed a prototype.  Based on Git  Master Slave replication.  Each collaboration Server will acts as a Master for its own GSICS products  Each collaboration Server will act as a Slave for other collaboration servers’ products 7

8. GSICS 2015 GDWG Breakout Session Implementation Details  Installation of Git on each Server  Installation of Python 2 v2.6 or greater on each Server (Not Python 3 – syntax changes)  Installation of Python scripts to detect and submit new files into the GIT repository  Installation of Python scripts to detect new files on the Master and download these to the Slave 8
