Configuring Enhanced Cooling Mode for Fans

The Enhanced Cooling Mode (ECM) feature provides additional cooling support using the third generation M1000e fans. The

Enhanced Cooling Mode (ECM) for fans is available only when all nine fan slots are populated with the new third generation M1000e

fans. The new third generation M1000e fans provide:

• Superior cooling to the installed blades compared to previous M1000e fan generations, when the ECM feature is enabled.

• Cooling equivalent to previous generations of M1000e fans at the same power, when the ECM feature is disabled.

ECM mode is recommended for:

• Blade server configurations with high Thermal Design Power (TDP) processors.

• Workloads where performance is a critical.

• Systems deployed in environments where the inlet temperature exceeds 30°C [86°F].

NOTE: In the Enhanced Cooling Mode (ECM), the new generation fans provide superior cooling features when

compared to current generation fans of M1000e chassis. This increased cooling is not always needed and comes at the

expense of higher acoustics (where the system can sound up to 40% louder) and increased system fan power. You can

enable or disable the ECM feature on the basis of cooling required for a chassis.

By default, the ECM feature is disabled on a chassis. The ECM enabling and disabling operations are recorded in the CMC logs. The

ECM mode state is maintained after CMC failovers and chassis AC power cycles.

You can enable or disable the ECM feature using the CMC Web interface or the RACADM CLI interface.

Configuring Enhanced Cooling Mode for Fans Using Web Interface
