• Cable-presence detection on most connectors
• Chipkill memory protection
• Double-device data correction (DDDC) for x4 DRAM technology DIMMs. 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 ServeRAID and 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
• LCD system information display panel (available on some models) and operator information panel
• Integrated Management Module (IMM)
• LCD system information display panel (available on some models) for memory DIMMs, microprocessors,
hard disk drives, solid state drives, power supplies, and fans
• 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 LCD system information display panel (if available).
• 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
• 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
• Single-DIMM isolation of excessive correctable error or multi-bit error by the Unified Extensible Firmware
Interface (UEFI)
• Solid state drives
• Standby voltage for system-management features and monitoring
• Startup (boot) from LAN through remote initial program load (RIPL) or dynamic host configuration
protocol/boot protocol (DHCP/BOOTP)
• System auto-configuring from the configuration menu
• System-error logging (POST and IMM)
• Systems-management monitoring through the Inter-Integrated Circuit (IC) protocol bus
• Uncorrectable error (UE) detection
• Upgradeable POST, Unified Extensible Firmware Interface (UEFI), diagnostics, IMM firmware, and
read-only memory (ROM) resident code, locally or over the LAN
.
