management network traffic from the production network. You can use the Setup utility to configure the
server to use a dedicated systems-management network or a shared network.
• UEFI-compliant server firmware
The UEFI firmware offers several features, including Unified Extensible Firmware Interface (UEFI)
version 2.1 compliance, Active Energy Management (AEM) technology, enhanced reliability, availability,
and serviceability (RAS) capabilities, and basic input/output system (BIOS) compatibility support.
UEFI replaces the BIOS and defines a standard interface between the operating system, platform
firmware, and external devices. The server is capable of booting UEFI-compliant operating systems,
BIOS-based operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
For more information about UEFI-compliant firmware, go to http://www.ibm.com/support/entry/
portal/docdisplay?lndocid=MIGR-5083207.
Note: The server does not support DOS.
• VMware ESXi embedded hypervisor
An optional USB flash device with VMware ESXi embedded hypervisor software is available for purchase.
Hypervisor is virtualization software that enables multiple operating systems to run on a host system at
the same time. See "Using the embedded hypervisor" on page 91 for additional information.

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 7160)
• 24-hour support center
• Automatic error retry and recovery
• Automatic restart on nonmaskable interrupt (NMI)
• Automatic restart after a power failure
• Backup 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
• 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 hard disk drives
• Operator information and light path diagnostics LED panels
• Integrated Management Module (IMM)
• Light path diagnostics LEDs for memory DIMMs, microprocessors, hard disk 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
