Maximizing Data Center Space and Efficiency with Middle of Row (MoR) Configuration

By Klaus Dafinger, Cooling Marketing Manager at Legrand.

With the increasing demands of high-density applications driven by the growth of artificial intelligence, data centers are grappling with challenges that can compromise the efficiency and reliability of networking equipment within their cabinets. High-density equipment generates substantial heat, necessitating robust cooling solutions. Moreover, the extensive cabling required for these setups exacerbates congestion, complicating access and maintenance. This results in a complex scenario where heat dissipation, space optimization, and cable management become critical issues to address to keep the data center's 'beating heart' running efficiently.

As data centers continue to grow in size and complexity, new approaches to managing the installation, operation, and maintenance of switching and routing infrastructure are emerging to meet the demand for higher performance, lower latency, and greater scalability. One such approach is the Middle-of-Row (MoR) configuration in data center cabinets.

What is Middle of Row (MoR)?

The MoR configuration strategically places networking equipment and connectivity panels in the middle of each row of server cabinets within a data center or server room. This central positioning enhances efficiency by enabling shorter cable runs and more organized cable management.

Why Choose MoR?

Streamlined Cable Management

Excessive cable length and complexity can lead to increased latency and signal interference. MoR configurations address this by shortening and simplifying cable runs, reducing congestion, and enhancing overall network performance. By centralizing networking equipment, this setup significantly reduces cable clutter, resulting in a more organized and manageable data center environment.

Efficiency

Densely packed networking equipment and cluttered cables can lead to increased heat, resulting in increased cooling costs. MoR configurations tackle this problem by shortening cable length and enhancing airflow and cooling efficiency.

Cost-Effectiveness

MoR configurations create a more stable and reliable operating environment by reducing the distance hot air must travel to reach cooling units. MoR also shortens cable lengths, reducing overall cabling costs. This cost efficiency is particularly advantageous for growing data centers that frequently upgrade and expand their infrastructure.

Easy Access and Maintenance

Cluttered cabling in cabinets makes it difficult for technicians to identify and access cables for maintenance and troubleshooting. Centrally located networking equipment allows technicians easier access for maintenance and upgrades, reducing downtime and boosting overall productivity in the data center.

Scalability

As your business grows, the need for scalable solutions becomes crucial. MoR's design inherently supports scalability, allowing seamless integration of additional equipment without major reconfiguration.

Space Optimization

Maximizing available space is essential, especially in high-density environments where space is limited. MoR configurations optimize space usage, allowing data centers to accommodate more server hardware without needing a larger physical footprint. This efficient use of space is crucial for maintaining operational effectiveness.

The MoR configuration is adaptable to a wide range of data center sizes and requirements, making it ideal for both small enterprises and large corporations. It strikes a perfect balance between space utilization, cost efficiency, and operational effectiveness.

The Minkels Nexpand SR Cabinet: Tailored for MoR Configurations

The Minkels Nexpand SR cabinet is a dedicated cabinet for housing switching and routing infrastructure separately from the server cabinets. It offers a centralized, safe, and secure environment for ongoing hardware installation, maintenance, and cable management, away from the servers. This spacious and innovative cabinet design, available in a width of 1000mm and 1200mm, means that more space can be freed up in the server cabinets for additional server hardware and means only one cabinet needs to be accessed for switching and routing work. This results in faster, safer, and more secure installation, operation and maintenance of switching and routing infrastructure.

Key Features:

Enhanced Accessibility and Security: This robust and reliable cabinet design includes an airtight base capable of supporting up to 100kg load, with a spacious structure providing technicians with easier access and a safer environment to work in. Its security features include lockable doors and panels.

Modular Design for Scalability: The Nexpand SR cabinet offers modularity essential in data center environments where scalability and adaptability are paramount. As your data center evolves, the Nexpand SR cabinet can be adjusted or expanded to meet new requirements. The modular and customizable design accommodates the integration of various accessories for cable management, doors, locking options, roof layouts, and PDU mounting.

Energy Efficiency and Cooling: The Nexpand SR cabinet optimizes airflow around the installed equipment via strategic vent placements and pathways, reducing hot spots and cooling requirements. This increases energy efficiency and the hardware's lifespan.

Advanced Cable Management: The Nexpand SR cabinet features an innovative double plate design that utilizes the space between the cabinet's height beams and side panels. It includes triangular access holes for attaching equipment and enhancing cable management. This allows cables to be routed and rerouted through the cabinet regardless of length or excess and in any configuration. 

Standard and Custom Solutions: Minkels offers a combination of standard and customer-specific configurations, ensuring a product that meets your unique data center needs. Whether a standard MoR setup or a tailored configuration, the Nexpand SR cabinet can be customized to suit specific requirements. 

Conclusion

The Minkels Nexpand SR cabinet stands out as a versatile, efficient, and scalable solution, making it an excellent choice for data centers implementing an MoR configuration. Its alignment with the core needs of MoR setups—optimized cable management, accessibility, scalability, and energy efficiency—makes it a perfect fit for modern data center infrastructures.
