Dell PowerEdge MX7000 Chassis Thermal Airflow Architecture Specification User Guide

Summary

Dell EMC PowerEdge MX7000 Chassis Thermal Airflow Architecture technical note. Describes the patent-pending multiple airflow zone design with three independent cooling zones: Zone 1 (blue) for eight compute/storage sleds cooled by five rear fans, Zone 2 (yellow) with four front fans for I/O modules, and Zone 3 for power supplies. This dedicated airflow path architecture ensures fresh air delivery to each component, enabling higher power density and future-generation scalability. Authored by Rick Eiland.

The unique thermal design of the new Dell Rick Eiland EMC Power Edge MX7000 chassis ensures that customers can confidently grow over many generations of IT technology, satisfying forthcoming demands for scalable expansion and performance while providing excellent investment SUMMARY protection. The multiple airflow zone architecture of the MX7000 is engineered Creating a modular to ensure fresh air is delivered to each component of the chassis, enabling infrastructure that can efficiently enhanced cooling of higher power and dense system configurations.

scalable design. The overall chassis architecture of the Power Edge MX7000 uses dedicated, independent airflow paths for each critical subsystem (Compute, I/O, and Power Dell EMC’s Power Edge MX7000 Supplies) to provide fresh air to each individual zone. This design allows for modular infrastructure meets expanded feature support, improved cooling efficiency, and the flexibility to these thermal challenges scale with future needs.

Frequently Asked Questions

How does the MX7000 handle airflow through compute sleds?

It uses direct orthogonal interconnects and 80mm fan modules, eliminating vertical midplanes that restrict airflow.

What is an advantage of the multiple zone architecture?

It delivers fresh air to every component (Compute, I/O, Power) independently, enhancing cooling and minimizing impedance.

How large of a power supply can the chassis support in Zone 3?

The PMUs can reliably deliver up to 3000W because they have an independent airflow path with no downstream components.
