Lenovo 6241, Installation And Service Manual

Administrators are able to find the right information and accomplish critical tasks faster through an
uncluttered, dashboard-driven graphical user interface (GUI). Centralizing and automating foundational
infrastructure deployment and lifecycle management tasks across large pools of systems frees up
administrator time, and makes resources available to end-users faster.
Lenovo XClarity is easily extended into the leading virtualization management platforms from Microsoft
and VMware using software plug-ins, called Lenovo XClarity Integrators. The solution improves workload
uptime and service-level assurance by dynamically relocating workloads from affected hosts in the cluster
during rolling server reboots or firmware updates, or during predicted hardware failures.

Reliability, availability, and serviceability
This topic provides an overview of the server reliability, availability, and serviceability (RAS) features.
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
• 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
• Corrected machine check interrupt (CMCI)
• Single-device data correction (SDDC) 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
• DRAM single device data correction (SDDC)
• Dynamic memory migration
• Enhanced DRAM single device data correction (SDDC+1)
• Enhanced DRAM double device data correction (SDDC+1)
• Error codes and messages
• Error correcting code (ECC) L3 cache and system memory
• Failed DIMM identification
• Full Array Memory Mirroring (FAMM) redundancy
• Hot-swap cooling fans with speed-sensing capability
• Hot-swap hard disk drives
• Hot-swap and redundant power supplies
• Integrated baseboard management controller (BMC) subsystem
• Integrated management module (IMM)
• LCD system information display panel
• Light path LEDs for DIMMs, microprocessors, PCIe adapters, hard disk drives, solid state drives, power
supplies, fans, PCIe modules, and I/O modules
• Memory address parity protection
• Memory demand and patrol scrubbing
