Reliability, Availability, And Serviceability - Lenovo HX1310 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, or 5-year parts and 5-year labor limited warranty (Machine
Type 8693)
• 24-hour support center
• Automatic error retry and recovery
• Automatic restart on nonmaskable interrupt (NMI)
• Automatic restart after a power failure
• Back up basic input/output system switching under the control of the integrated management module
(IMM)
• Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
• Cable-presence detection on most connectors
• Chipkill memory protection
• Double-device data correction (DDDC) for x4 DRAM technology DIMMs (available on 16 GB DIMMs only).
Ensures that data is available on a single x4 DRAM DIMM after a hard failure of up to two DRAM DIMMs.
One x4 DRAM DIMM in each rank is reserved as a space device.
• Diagnostic support for Ethernet adapters
• Error codes and messages
• Error correcting code (ECC) L3 cache and system memory
• Full Array Memory Mirroring (FAMM) redundancy
• Hot-swap cooling fans with speed-sensing capability
• Hot-swap hard disk drives
• Integrated Management Module (IMM)
• Memory mirroring and memory sparing support
• 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
• Nonmaskable interrupt (NMI) button
• Parity checking on the small computer system interface (SCSI) bus and PCI-E and PCI buses
• Power management: Compliance with Advanced Configuration and Power Interface (ACPI)
• Power-on self-test (POST)
• Proactive Platform Alerts (including Predictive Failure Analysis and Self-Monitoring, Analysis and
Reporting Technology alerts): microprocessors, voltage regulators, memory, internal storage (SAS/SATA
hard disk drives and solid-state drives, NVMe solid-state drives, M.2 storage, flash storage adapters),
fans, power supplies, RAID controllers, and server ambient and sub-component temperatures
• Redundant Ethernet capabilities with failover support
• Redundant hot-swap power supplies and redundant hot-swap fans
• Redundant network interface card (NIC) support
• Remind button to temporarily turn off the system-error LED
• Remote system problem-determination support
• ROM-based diagnostics
• ROM checksums
