What your server offers
Use this information to get an overview of the server functions, features, capabilities, and technologies.
The server uses the following features and technologies:
• 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 http://

• 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.
Note: 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” on page 165.
• Features on Demand software Ethernet support
The server provides Features on Demand software Ethernet support. You can purchase a Features on
Demand software upgrade activation key for Fiber Channel over Ethernet and iSCSI storage protocols that
