Chapter 4. Reliability, availability, and serviceability Reliability, availability, and serviceability (hereafter referred to as RAS) are three important server design features. The RAS features help you to ensure the integrity of the data stored on the server, the availability of the server when you need it, and the ease with which you can diagnose and correct problems. The server has the following RAS features: • Advanced Configuration and Power Interface (ACPI) • Advanced Desktop Management Interface (DMI) • Automatic memory downsizing on error detection • Automatic restart on non-maskable interrupt (NMI) • Availability of microcode level • Built-in, menu-driven setup, system configuration, and RAID configuration • Built-in monitoring for fan, temperature, and voltage • Cooling fans with speed-sensing capability • ECC DDR3 SDRAM with Serial Presence Detect (SPD) • Error codes and messages to help you identify problems • Generating error logs for the power-on self-test (POST) failures • Hot-swap SAS hard disk drives • Integrated Ethernet controllers • Intelligent Platform Management Interface (IPMI) 2.0 • Power-on self-test (POST) • Redundant Ethernet connection with failover capability (requires an optional Ethernet card) • Standby voltage for system-management features and monitoring • System-error light-emitting diode (LED) on the front panel • Vital product data (VPD), including the serial number information and replacement part numbers, stored in the nonvolatile memory for easier remote maintenance © Copyright Lenovo 2010, 2012 11

Chapter 4.
Reliability, availability, and serviceability
Reliability, availability, and serviceability (hereafter referred to as RAS) are three important server design
features. The RAS features help you to ensure the integrity of the data stored on the server, the availability of
the server when you need it, and the ease with which you can diagnose and correct problems.
The server has the following RAS features:
•
Advanced Configuration and Power Interface (ACPI)
•
Advanced Desktop Management Interface (DMI)
•
Automatic memory downsizing on error detection
•
Automatic restart on non-maskable interrupt (NMI)
•
Availability of microcode level
•
Built-in, menu-driven setup, system configuration, and RAID configuration
•
Built-in monitoring for fan, temperature, and voltage
•
Cooling fans with speed-sensing capability
•
ECC DDR3 SDRAM with Serial Presence Detect (SPD)
•
Error codes and messages to help you identify problems
•
Generating error logs for the power-on self-test (POST) failures
•
Hot-swap SAS hard disk drives
•
Integrated Ethernet controllers
•
Intelligent Platform Management Interface (IPMI) 2.0
•
Power-on self-test (POST)
•
Redundant Ethernet connection with failover capability (requires an optional Ethernet card)
•
Standby voltage for system-management features and monitoring
•
System-error light-emitting diode (LED) on the front panel
•
Vital product data (VPD), including the serial number information and replacement part numbers, stored in
the nonvolatile memory for easier remote maintenance
