PAM Software Package
The Bull NovaScale Server is equipped with an integrated Platform Administration and
Maintenance software package, otherwise known as the PAM software package.
One part of PAM software is an embedded application (MAESTRO) running on the Platform
Management Board(s) (PMB) and the other is an external application (PAM Kernel / Web
User Interface) running on the Platform Administration Processor (PAP) unit under Microsoft
Windows.

The PAM Web–based administration and maintenance tools give you immediate insight into
system status and configuration. You will use PAM software to operate, monitor, and
configure your Bull NovaScale Server.
As soon as your system is connected to the power supply, the PAP unit running Microsoft
Windows and PAM software also powers up. For further information about connecting to
PAM, see
Connecting to the PAM Web Site , on page 2-2.
PAP Unit Mirroring and Failover Policy
Most configuration, administration, and maintenance activities are carried out from the PAP
unit. To ensure a high level of data integrity and availability, the PAP unit is equipped with
two extractable mirrored disks. Mirroring writes and updates data across both disks,
creating a single logical volume with completely redundant information on each disk. If one
disk fails, it can be replaced without losing data.
Note:
For enhanced data integrity and availability, the PAP unit can be equipped with a third disk.
