Light path diagnostics
Light path diagnostics provides light-emitting diodes (LEDs) to help you diagnose
problems. For more information, see the Problem Determination and Service
Guide .
v
Power throttling
Each blade server is powered by two BladeCenter redundant power-supply
modules. By enforcing a power policy known as power domain oversubscription,
the BladeCenter unit can share the power load between two power modules to
ensure efficient power for each device in the BladeCenter unit. This policy is
enforced when the initial power is applied to the BladeCenter unit or when a
blade server is inserted into the BladeCenter unit.
The following settings for this policy are available:
– Redundant without performance impact
– Redundant with performance impact
– Nonredundant
You can configure and monitor the power environment by using the management
module. For more information about configuring and using power throttling, see
the management-module documentation or http://www.ibm.com/support/.
Reliability, availability, and serviceability features
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These RAS features help to ensure the integrity of the data
that is stored in the blade server, the availability of the blade server when you need
it, and the ease with which you can diagnose and correct problems.
The blade server has the following RAS features:
v
Advanced Configuration and Power Interface (ACPI)
v
Automatic error retry or recovery
v
Automatic server restart
v Built-in monitoring for temperature, voltage, hard disk drives, and flash drives
v Chipkill
™
memory for dual inline memory modules (DIMMs) with a capacity of 1
GB or greater
v Customer-upgradeable basic input/output system (BIOS) code
v Customer support center 24 hours per day, 7 days a week

v Diagnostic support of Ethernet controllers
v Error codes and messages
v ECC protection on the L2 cache
v ECC memory
v
Failover Ethernet support
v
Light path diagnostics feature
v
Power-on self-test (POST)
v
Predictive Failure Analysis (PFA) alerts
v
Service processor that communicates with the management module to enable
remote blade server management
v
SDRAM with serial presence detect (SPD) and vital product data (VPD)
v
System error logging
v
VPD (includes information stored in nonvolatile memory for easier remote
viewing)
v
