4. How Centera Works: Application Example
Title
Month Year
How Centera Works: Application Example
Centera performs CA calculation and sends address back to application
Object is created
and sent to application server
LAN CA
Application server sends object to Centera over IP Network DB
Database stores CA for future reference
Content Addressing
Digital fingerprint
Globally unique
Location- independent
Content address algorithm

5. Benefits of Content Address and Storage-based Metadata

What Centera Brings to an Information Archive
Eliminates management overhead
Address is location-independent
Improved storage efficiency
Identical objects are stored only once
Guaranteed integrity
Absolute assurance of content authenticity
Enforces application retention and disposition policies in storage
Object level retention
Centera Specific Benefits

8. Integration of the Database to Centera

Integration of the Database to Centera
What are we trying to achieve?
Fixed content written to MySQL is persisted to Centera, transparent to the application

11. Demonstration of Principle – MySQL
Title
Month Year
Demonstration of Principle – MySQL
We have modified the open source MySQL to illustrate the idea of transparent access to Centera
This is not a product – merely a vehicle to demonstrate the concept of a database integration …

12. Demonstration of Transparent Access
Step 4
Step 3
Centera
SDK
Read
Persist
Interrogate
Step 2
Centera
SDK
Create
Write
JDBC
Step 1

13. Demonstration of Transparent Access1
Step
Create the database
DDL processor updated to set a Flag when:
COMMENT = ‘Centera’
Could have read configuration from a file
Transparency

14. Demonstration of Transparent Access2
Step
Populate the tables
Simple application created to populate a table
An image is written as BLOB data

15. Demonstration of Transparent Access3
Step
Verify the data made it to Centera
ClipBrowser allows inspection of
Data model
metadata

16. Demonstration of Transparent Access4
Step
Show transparent access
Use mySQL QueryBrowser to inspect BLOB data
Image is retrieved transparently from the Centera
No code updates to the application

17. Access Method for Centera
Possible Benefits
Database
Access Method for Centera
Customers don’t have to store all BLOB content on high speed storage
Much BLOB content is already ‘fixed’ upon ingest
Cost effective use of infrastructure
This is a real problem for some very large customers
Huge amounts of new content can be driven through the database
Encourages apps to write fixed content to the DB
The Database becomes a solution for structured and unstructured content

18. Possible Benefits (cont’d)
MySQL
Access Method for Centera
One infrastructure for fixed content – application wide
Single point of visibility for retention & compliance
Content ‘state’ is always stored in the database anyway
Backup sizes reduced
Many Centera customers don’t back them up – merely replicate offsite.
Size of backup can be a reason for not writing BLOBs to the DB

19. Possible Benefits (cont’d)
MySQL
Access Method for Centera
Partner’s don’t need to write to the Centera SDK
Just write to fixed content as BLOBs
Database can control retention across the application space
Focus of the compliance infrastructure
Could be very valuable to large customers with many applications
Offer up a new set of compliance and disposition services to applications

20. Isn’t this the same as existing DB archiving solutions?
Typical database archiving solutions work on rows
So do most database ILM solutions
May not be transparent to all applications
Could use a combination of transparency techniques such as replicating application UIs
