ETERNUS AF/ETERNUS DX checks data security using Data Block Guard technology.
While this is very important, it does not cover situations where data corruption occurs in the interfaces between systems. This is because Data Block Guard only verifies data after it has reached the storage device.
That is why Fujitsu also uses another data protection mechanism called "DB (Data Base) Data Guard". This combination of data security measures Oracle Data Base, means ETERNUS AF/ETERNUS DX is able to deliver very robust data integrity.
As data is written into the ETERNUS AF/ETERNUS DX, the database adds check codes. The ETERNUS AF/ETERNUS DX has knowledge of the logic of these check codes and where the codes are placed enabling it to verify the data using the check codes.
If an ETERNUS AF/ETERNUS DX identifies any data corruption, it will stop further operation and notify the administrator; thereby preventing the use of data known to be corrupt.
