In addition to improving airflow and enhancing cooling, use of Direct Orthogonal Connectors in the PowerEdge
MX7000 enables the formation of a comprehensive interconnection for high speed signal transmission between
compute/storage modules and switch (I/O) modules, as well as for effective power delivery to these modules. Figure 4
below illustrates direct orthogonal interconnections between a vertical Compute Module and horizontal Switch Module,
as well as power delivery using both Vertical and Horizontal Power Distribution PWA’s to those modules:

Conclusion
While earlier servers and modular systems relied on a traditional midplane architecture, implementation of innovative
Direct Orthogonal Connectors in the new PowerEdge MX7000 eliminates the midplane and greatly optimizes airflow
through the compute and switch modules. This enhances cooling and ensures that current and future high-power
processors and DIMM’s can be cooled more effectively, even at high ambient temperatures. Additionally, signal
integrity will be optimal without being compromised by long Printed Circuit Board (PCB) traces, allowing for high speed
signals (including PCIe Gen 4).
