4. Case Study

5. Case Study: Erasmus University
Case: store 100 human genomes...
...for the first year.
Grow further in the next years.
Current problems
Too much data, and growing
Taking too much time to diagnose

6. Data is a sample DNA variations set
Table: CG_VAR
– Size: 133’425’004’544
– Extents: 2’228
– Blocks: 16’287’232
No indexes
No constraints
Tests are done on VX Company & PROACT half rack
Exadata V2

7. What is done?
In all cases the following simple SQL is executed:
SQL> select count(*) from cg_var;

17. Case study
9,300 Retail stores
98000 Employees
Based in Hong Kong
In Netherlands brands ‘Kruidvat’ and ‘Trekpleister’ are
used.

18. Case study AS Watson
Investigation into user satisfaction
BI performance issues
Better reports needed
Project started for new DWH
Performance 10x faster

19. Case study AS Watson
POC Netezza
Achieved 10 times performance improvement
But change in platform results in change of technique
POC IBM
Hardware: large P7 with huge storage system
Expected 30-40 times performance improvement
In real life achieved 15 times improvement
POC Oracle Exadata
On exadata quarter rack
Achieved 10-200 times improvement

20. Case study AS Watson
AS Watson decided not to go ahead with IBM
Netezza and Exadata remained
Netezza
Pro’s
• Netezza helps with importing data
• Fast
Con’s
• Again a new vendor
• No knowledge in organisation
• No OLTP

21. Case study AS Watson
Exadata
Faster than Netezza in general
Pro’s
• OLTP possible
• Possibility to consolidate
• Fits in existing Sun environment
• Already user of Oracle database software
Con’s
• Upgrade to newest version needed
• Extra knowledge of Oracle database software needed

22. Case study AS Watson
Conclusion
Price difference 20k
Extra consultancy offered
Order received for 300k, system already running in UK
