BIOS-based adapters as well as UEFI-compliant adapters. For more informationabout UEFI-compliant firmware, go to http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5083207.Note: The server does not support DOS.v VMware ESXi embedded hypervisorAn optional USB flash device with VMware ESXi embedded hypervisor softwareis available for purchase. Hypervisor is virtualization software that enablesmultiple operating systems to run on a host system at the same time. Install theUSB flash device in the USB embedded hypervisor flash device connectors onthe system board (see “System-board internal connectors” on page 28). See“Using the embedded hypervisor” on page 155 for additional information.Reliability, availability, and serviceabilityThis information lists the server reliability, availability, and serviceability features.Three 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 8722)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 Single-device data correction (SDDC) for x4 DRAM technology DIMMs(available on 16 GB DIMMs only). Ensures that data is available on a single x4DRAM DIMM after a hard failure of up to two DRAM DIMMs. One x4 DRAMDIMM in each rank is reserved as a space device.v 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 cooling fans with speed-sensing capabilityv Hot-swap hard disk drivesv Hot-swap power suppliesv Information and light path diagnostics LED panelsv Integrated management module (IMM)v Light path diagnostics LEDs for DIMMs, microprocessors, hard disk drives, solidstate drives, power supplies, and fansv Memory mirroring and memory sparing supportv Memory error correcting code and parity testv Memory downsizing (non-mirrored memory). After a restart of the server afterthe memory controller detects a non-mirrored uncorrectable error and thememory controller cannot recover operationally, the IMM logs the uncorrectable14 System x3750 M4 Types 8722 and 8733: Installation and Service Guide
