MOR in a data center stands for Middle of Row. It refers to a specific architectural design for placing network cabinets within a row of server cabinets.
Understanding Middle of Row (MOR) Architecture
Based on the provided information, Middle of Row (MOR) architecture is an improvement over the traditional End of Row (EOR) architecture. Its core principle is the strategic placement of the network access cabinet.
As the reference states, "Middle of Row (MOR) architecture is an improvement over the EOR architecture because it provides a unified network access cabinet for the servers." Instead of locating the network equipment at one end of the row, the network cabinet is integrated within the middle or central section of the row of server cabinets.
Key Benefits of MOR
Placing the network cabinet in the middle of the row offers several practical advantages for data center operations and infrastructure management. The reference specifically highlights these benefits:
- Provides a Unified Network Access Cabinet: Centralizes the network connection point for all servers within that specific row.
- Shortens Distance: The network cabinet is "placed in the middle-of-row cabinets to shorten the distance between it and server cabinets." This is a primary driver for adopting MOR.
- Simplifies Cable Management: Shorter cable runs lead to less clutter and easier organization of network cabling connecting servers to the network switch.
- Simplifies Maintenance: With network access and shorter, better-managed cables, maintenance tasks like patching or troubleshooting become more straightforward.
By reducing the length of network cables and centralizing the network access point, MOR helps optimize connectivity within a data center row, contributing to better organization and operational efficiency compared to designs where network cabinets are located only at the ends of rows.
