private or commercial CA). Firewalls on chassis and servers can be configured to accept incoming
requests from only Lenovo XClarity Administrator.
• Service and support
Lenovo XClarity Administrator can be set up to collect and send diagnostic files automatically to your
preferred service provider when certain serviceable events occur in Lenovo XClarity Administrator and the
managed endpoints. You can choose to send diagnostic files to Lenovo Support using call home or to
another service provider using SFTP. You can also manually collect diagnostic files, open a problem
record, and send diagnostic files to the Lenovo Support Center.
• Task automation using scripts
Lenovo XClarity Administrator can be integrated into external, higher-level management and automation
platforms through open REST application programming interfaces (APIs). Using the REST APIs, Lenovo
XClarity Administrator can easily integrate with your existing management infrastructure. You can also run
Lenovo XClarity cmdlets in a Microsoft PowerShell session to automate certain management functions.
The cmdlets use Lenovo XClarity Administrator REST APIs and can automate functions
• Integration with other management software
Lenovo XClarity Administrator is available stand-alone or as a bundled offering that is known asLenovo
XClarity Pro. Lenovo XClarity Pro is composed of the base Administrator product plus two Lenovo XClarity
Integrator modules that provide integration into Microsoft Systems Center or VMware vCenter. Together,
these tools provide discovery, monitoring, configuration, and management functions to reduce the cost
and complexity of routine system administration for System x, NeXtScale, and Flex System endpoints.

Reliability, availability, and serviceability features

Three of the most important features in compute node design are reliability, availability, and serviceability
(RAS). These RAS features help to ensure the integrity of the data that is stored in the compute node, the
availability of the compute node when you need it, and the ease with which you can diagnose and correct
problems.
The compute node has the following RAS features:
• 24-hour support center
• Advanced Configuration and Power Interface (ACPI)
• Automatic server restart (ASR)
• Built-in diagnostics using DSA Preboot
• Built in monitoring for temperature, voltage, and hard disk drives
• Customer support center 24 hours per day, 7 days a week
• Customer upgrade of flash ROM-resident code and diagnostics
• Customer-upgradeable Unified Extensible Firmware Interface (UEFI) code and diagnostics
• ECC protected DDR3 DIMMs
• ECC protection on the L2 cache
• Error codes and messages
• Integrated management module II (IMM2) that communicates with the Chassis Management Module to
enable remote systems management
• Light path diagnostics
• Memory mirroring mode support
• Microprocessor built-in self-test (BIST) during power-on self-test (POST)
• Microprocessor Intel QuickPath Interconnect bus and CRC checking
