Note: The power management policy that you have implemented for the
BladeCenter S system determines the result of a power module failure.
Power modules also provide cooling fans for the storage modules. Therefore,
if you are using storage module 1, you must install power modules 1 and 2. If
you are using storage module 2, you must install power modules 3 and 4.
– Fan modules . In normal operation, fan modules share the cooling in the
BladeCenter S system. If one fan module fails, the other three fan modules
handle the entire load. You can replace a fan module without shutting down
the BladeCenter S system.
– BladeCenter S system midplane . The midplane has the following
characteristics:
- Redundant high-speed serialize/deserialize (SERDES) interconnects
between blade servers and switches
- I2C communication between the advanced management module and all
modules (except blade servers)
- RS-485 (EIA 485) communication between the advanced management
module and blade servers
- Analog video connectors from the blade servers to the advanced
management module
- USB connections between the blade servers and the advanced management
module
–
Redundant storage access
. Installing a pair of SAS connectivity modules or
SAS RAID controller modules in I/O module bays 3 and 4 provides support
for redundant access to the storage modules in the BladeCenter S chassis (if
both storage modules are installed).
v
Systems management
The advanced management module is used to communicate with the service
processor in each blade server to provide system monitoring, event recording,
and alerts. You can manage the BladeCenter S chassis, its devices, and the blade
servers remotely.
