With this policy, the total allowable power draw is limited to one less than
the number of power modules when more than one power module is
present. One power module can fail without affecting blade server operation.
Blade servers will power on only if they can operate without throttling if
there is a power module failure. The number of blade servers allowed to
power on is determined by the power available from one less than the total
number of power modules. If a single power module fails, all the blade
servers that are powered on will continue to operate at normal performance
levels. If two or more power modules fail, the BladeCenter S chassis could
power off.
This policy is intended when you have two to four power modules installed
and a single 110-volt or 220-volt AC power source. Each power module is on
its own dedicated circuit.
v
Power module redundancy with blade throttling allowed
With this policy, the total allowable power draw is limited to one less than
the number of power modules when more than one power module is
present. One power module can fail without affecting blade server operation,
but multiple power module failures can cause the chassis to power off.
This policy allows you to draw more total power from the chassis. However,
in case of a power module failure, the advanced management module might
have to throttle down some blade servers to keep the chassis operational.
Blade servers will be allowed to power on as long as the power consumed is
less than or equal to the total power under this policy. If a single power
module fails, processors on blade servers that are capable of throttling, will
throttle in order to reduce the power consumed to less than or equal to the
rated capacity of the power module. Blade servers will power up in a
throttled state in some configurations. Upon restoration of power
redundancy, the blade processors will return to their normal performance
levels.
This policy is intended when you have two to four power modules installed
and a single 110-volt or 220-volt AC power source. Each power module is on
its own dedicated circuit.
v
Non-redundant
Blade servers will be allowed to power on as long as the power consumed is
less than or equal to the total power of all installed power modules.
Processors return to their normal power states when power redundancy is
restored.
Note:
There may be certain configurations that might result in loss of power
in the domain.
4.
Verify that the blade server is supported in the BladeCenter S chassis.
5.
Contact IBM support.
I-error messages displayed for an Intel-based blade server
I-error messages are displayed in the advanced management module event log.
Use this procedure to resolve problems that cause I-error messages.
Problem
The advanced management module event log displays I-error messages for one of
the Intel-based blade servers.
