Reliability, availability, and serviceability features
Reliability, availability, and serviceability 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.
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 BIOS recovery (ABR)
v Automatic server restart (ASR)
v Built-in monitoring for temperature, voltage, hard disk drives.
v Customer support center 24 hours per day, 7 days a week.
v Customer-upgradeable basic input/output system (BIOS) code and diagnostics
v Diagnostic support of Ethernet controllers
v ECC protection on the L2 cache
v Error codes and messages
v Hot-swap SAS or solid state storage drives, fixed SATA or solid state storage
v Light path diagnostics feature
v Memory parity testing
v Microprocessor built-in self-test (BIST) during power-on self-test (POST)
v Microprocessor serial number access
v PCI PMI 2.2
v PCI-X 1.0a
v PCI Express 1.0a
v POST
v ROM resident diagnostics
v Registered ECC DDR2 667 memory

BladeCenter HS12 Type 8014 or 8028: Installation and User's Guide
PCI Express is a serial interface that is used for chip-to-chip interconnect and
expansion adapter interconnect. With the blade expansion connector you can
add optional I/O and storage devices.
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 sufficient 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/systems/support/.
