7.2 Data Storage

The MRS6100 data includes BAM data and FAM data.

7.2.1 BAM Data

All BAM data are stored in the SQL Server of the BAM. Through the data
management program on the BAM, operator authorities can be managed in a
hierarchical mode.
The BAM data can be backed up automatically and periodically. When some
important data are modified, manual backup also can be performed.

7.2.2 FAM System Data

The FAM system data are stored in the FAM with backup in Flash memory or
without backup in Flash memory.
I. FAM system data with backup in Flash memory
After the data are loaded to the BIOS successfully, it automatically backs up data
into Flash memory. When the system is powered on, according to the BAM soft
switch, you can choose to reload data from the BAM or directly read system data
from the Flash memory on this board.
When the BAM carries out data setting, the backup program module of the active
board automatically backs up the modified static data to its Flash memory or the
memory database of the standby database. Moreover, the backup program of the
standby database automatically synchronizes its changed memory database to its
Flash memory.
II. FAM system data without backup in Flash memory
If the system configuration data on the board have no backup in the Flash memory,
the board data must be loaded from the BAM when they are started each time.
When the BAM performs data setting, it sends the data to the active and standby
boards simultaneously. Meanwhile, the changed data in an active board are not
backed up to the standby board.
