  • Lenovo XClarity Energy Manager

    Your server supports Lenovo XClarity Energy Manager, a standalone user interface that you can use to monitor and manage the power consumption and temperature of supported servers, including:

    • Monitoring energy consumption, estimating the power demand, and reallocating power to servers as needed.

    • Monitoring the temperature and cooling capacity of servers.

    • Sending notifications when certain events occur or when thresholds are exceeded.

    • Limiting the amount of energy that an endpoint consumes using policies.

    • Optimizing energy efficiency by monitoring real-time inlet temperatures, identifying low-usage servers based on out-of-band power data, measuring power rangers for different server models, and evaluating how servers accommodate new workloads based on the availability of resources.

    • Reducing the power consumption to a minimum level to prolong service time during an emergency power event (such as a data-center power failure).

    For more information about how to download, install, and use Lenovo XClarity Energy Manager, see Lenovo Systems Management website.

  • Dynamic System Analysis (DSA)

    The server comes with the Lenovo Dynamic System Analysis™ (DSA) Preboot diagnostic program stored in the integrated USB memory on the server. DSA collects and analyzes system information to aid in diagnosing server problems, as well as offering a rich set of diagnostic tests of the major components of the server. DSA creates a DSA log, which is a chronologically ordered merge of the system-event log (as the IPMI event log), the integrated management module (IMM) event log (as the ASM event log), and the operating-system event logs. You can send the DSA log as a file to Lenovo Support or view the information as a text file or HTML file.
    This documentation includes references to IBM web sites, products, and information about obtaining service. IBM is Lenovo's preferred service provider for the Lenovo System x products.

    Two editions of Dynamic System Analysis are available: DSA Portable and DSA Preboot. For more information about both editions, see DSA editions.

  • Light path diagnostics

    Light path diagnostics provides LEDs to help you diagnose problems. For more information about light path diagnostics and the LEDs, see LCD system information display panel and Light path diagnostics LEDs description.

  • Memory mirroring

    Memory mirroring provides a redundant copy of all code and data that are addressable in the configured memory map. Through the microprocessor memory controller chip set, memory mirroring replicates and stores data across DIMMs on two or four memory channels simultaneously. If a failure occurs, the memory controller switches from the DIMMs on the primary channel to the DIMMs on the backup channel. To enable memory mirroring through the Setup utility, select System Settings → Memory → Memory Mode → Mirroring. For information about installing DIMMs for memory mirroring, see Memory mirroring and Installing a memory module for more information.

  • Memory sparing

    The server supports memory sparing. Memory sparing reserves memory capacity for failover in the event of a DIMM failure, and the reserved capacity is subtracted from the total available memory. Memory sparing provides less redundancy than memory mirroring does. If a predetermined threshold of correctable errors is reached, the contents of the failing DIMM are copied to the spare memory, and the failing DIMM or rank is disabled. To enable memory sparing through the Setup utility, select System Settings → Memory → Memory Mode → Sparing. For information about installing DIMMs for memory sparing, see Memory rank sparing.

  • Mobile access to Lenovo Service Information Web page

    The server provides a quick reference (QR) code on the system Service Card that you can scan with a mobile device using a QR code reader application to get quick access to the Lenovo Service Information Web page.
