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
Lenovo System x Server Firmware (server firmware) offers several features, including Unified Extensible
Firmware Interface (UEFI) 2.1 compliance; Active Energy Manager 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. UEFI-compliant System x servers are capable of booting
UEFI-compliant operating systems, BIOS-based operating systems, and BIOS-based adapters as well
as UEFI-compliant adapters.
Note: The server does not support DOS (Disk Operating System).
• 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. The USB embedded hypervisor flash device can be installed in the internal USB
connector. For more information about using the embedded hypervisor, see "Using the embedded
hypervisor" on page 113.

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 5460)
• 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
• 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 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
• Information and light path diagnostics LED panels
• Integrated Management Module (IMM)
• Light path diagnostics LEDs 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,
