BX900 S1 Operating Manual 17
Technical data
Management blade
The PRIMERGY BX900 S1 system unit has slots for two redundant, hot-swap
management blades with an integrated management solution for complete
remote administration of the system. The base configuration of the system unit
contains one management blade (for details, see section "Management blades"
on page 125).
Power supply
The system unit has six installation bays for hot-plug power supply units which
automatically set themselves to a voltage in the range of 100 - 240 V. The base
configuration includes three power supply units. As an option, you can set up a
redundant power supply with three additional power supply units. If a power
supply unit fails, the redundant configuration assures continued operation. The
defective power supply unit can be replaced during operation (for further details
see section "Hot-plug power supply units" on page 126).
Cooling
Cooling of the system is ensured by two fan units in each power supply unit and
by the fan modules. Each of the fan units contains 2x2 fans. The fan modules
have the same aspect ratio as the power supply units. Depending on the
number of installed server blades and storage blades in the system unit, empty
power supply installation bays must be fitted with fan modules. The
configuration is redundant and offers hot-swap functionality (for more
information, see "Hot-plug power supply units" on page 126).
High level of availability and failure protection
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
the event of an error and automatically "hides" the defective system
components.
The PDA (Prefailure Detection and Analyzing) technology from Fujitsu
Technology Solutions analyzes and monitors all components that are critical for
system reliability.
The hot-swap components provide additional failure protection. Failure
protection for the entire system is ensured by four redundant hot-swap power
supply units as well as redundant hot-swap fans.
