multiple operating systems to run on a host system at the same time. See “Usingthe embedded hypervisor” on page 84 for additional information.Reliability, availability, and serviceabilityThree important computer design features are reliability, availability, andserviceability (RAS). The RAS features help to ensure the integrity of the data thatis stored in the server, the availability of the server when you need it, and the easewith which you can diagnose and correct problems.Your server has the following RAS features:v 3-year parts and 3-year labor limited warranty (Machine Type 7160)v 24-hour support centerv Automatic error retry and recoveryv Automatic restart on nonmaskable interrupt (NMI)v Automatic restart after a power failurev Backup basic input/output system switching under the control of the integratedmanagement module (IMM)v Built-in monitoring for fan, power, temperature, voltage, and power-supplyredundancyv Cable-presence detection on most connectorsv Chipkill memory protectionv Diagnostic support for ServeRAID and Ethernet adaptersv Error codes and messagesv Error correcting code (ECC) L3 cache and system memoryv Full Array Memory Mirroring (FAMM) redundancyv Hot-swap hard disk drivesv Operator information and light path diagnostics LED panelsv Integrated Management Module (IMM)v Light path diagnostics LEDs for memory DIMMs, microprocessors, hard diskdrives, power supplies, and fansv Memory mirroring and memory sparing supportv Memory error correcting code and parity testv Memory down sizing (non-mirrored memory). After a restart of the server afterthe memory controller detected a non-mirrored uncorrectable error and thememory controller cannot recover operationally, the IMM logs the uncorrectableerror and informs POST. POST logically maps out the memory with theuncorrectable error, and the server restarts with the remaining installed memory.v Menu-driven setup, system configuration, and redundant array of independentdisks (RAID) configuration programsv Microprocessor built-in self-test (BIST), internal error signal monitoring, internalthermal trip signal monitoring, configuration checking, and microprocessor andvoltage regulator module failure identification through light path diagnosticsv Nonmaskable interrupt (NMI) buttonv Parity checking on the small computer system interface (SCSI) bus and PCI-Ebusesv Power management: Compliance with Advanced Configuration and PowerInterface (ACPI)v Power-on self-test (POST)v Predictive Failure Analysis (PFA) alerts on memory, microprocessors, SAS/SATAhard disk drives or solid state drives, fans, power supplies, and VRMv Redundant Ethernet capabilities with failover supportv Redundant hot-swap power suppliesv Redundant network interface card (NIC) supportv Remind button to temporarily turn off the system-error LED on the optionaladvanced operator information panel12 System x3530 M4 Type 7160: Installation and Service Guide
