Reliability, Availability, And Serviceability - Lenovo x3300 M4 7382 Installation And Service Manual

Reliability, availability, and serviceability

Three important computer design features are reliability, availability, and serviceability (RAS). The RAS
features help to ensure the integrity of the data that is stored in the server, the availability of the server when
you need it, and the ease with which you can diagnose and correct problems.
Your server has the following RAS features:
• 3-year parts and 3-year labor limited warranty (Machine Type 7382)
• 24-hour support center
• Automatic error retry and recovery
• Automatic restart on non-maskable interrupt (NMI)
• Automatic restart after a power failure
• Backup basic input/output system switching under the control of the integrated management module II
(IMM2)
• Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
• Cable-presence detection on most connectors
• Chipkill memory protection
• Diagnostic support for ServeRAID and Ethernet adapters
• Error codes and messages
• Error correcting code (ECC) L3 cache and system memory
• Simple-swap cooling fans with speed-sensing capability
• Hot-swap hard disk drives
• Information and light path diagnostics LED panels
• Integrated Management Module II (IMM2)
• Light path diagnostics LEDs for memory DIMMs, microprocessors, hard disk drives, power supplies, and
fans
• Memory mirrored channel support (memory mirrored channel are mutually exclusive of each other)
• Memory error correcting code and parity test
• Memory down sizing (non-mirrored memory). After a restart of the server after the memory controller
detected a non-mirrored uncorrectable error and the memory controller cannot recover operationally, the
IMM logs the uncorrectable error and informs POST. POST logically maps out the memory with the
uncorrectable error, and the server restarts with the remaining installed memory.
• Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration
programs
• Microprocessor built-in self-test (BIST), internal error signal monitoring, internal thermal trip signal
monitoring, configuration checking, and microprocessor and voltage regulator module failure identification
through light path diagnostics
• Parity checking on the small computer system interface (SCSI) bus and PCI-E buses
• Power management: Compliance with Advanced Configuration and Power Interface (ACPI)
• Power-on self-test (POST)
• Predictive Failure Analysis (PFA) alerts on memory, microprocessors, SAS/SATA hard disk drives or solid
state drives, fans, power supplies, and VRM
• Redundant Ethernet capabilities with failover support
• Redundant hot-swap power supplies
• Redundant network interface card (NIC) support
• Remind button to temporarily turn off the system-error LED on the optional advanced operator information
panel
• Remote system problem-determination support
• ROM-based diagnostics
• ROM checksums
• Serial Presence Detection (SPD) on memory, VPD on system board, power supply, and hard disk drive or
solid state drive backplanes, microprocessor and memory expansion tray, and Ethernet cards
• DIMM isolation of excessive correctable error or multi-bit error by the Unified Extensible Firmware
Interface (UEFI)
