Most of us nowadays usually identify storage infrastructures with servers, switches, and storage arrays while the physical cabling and patch panel layouts that connect these components are rarely taken into account in architectural discussions. Due to this neglect of the physical infrastructure, an "illusion of isolation" has been created in which people assume that since logical separation exists, the physical independence is also guaranteed. However, it is through the physically shared cable pathways that interdependencies become visible making performance, reliability, and troubleshooting very much concerned with the hidden interdependencies factor. The paper reveals how physical-layer materials in data centers can have a great impact on the performance of the whole center. It shows that through physical infrastructure, single failure points were formed. It has been found that, although redundant links are commonly found to be going through the same physical paths, the administrators remain unaware of this fact. In addition to this, there is an increase in signal interference, congestion, and extended mean-time-to-repair (MTTR) due to poor cabling practices. Without the physical layer, resilience evaluation is not accurate. Proper infrastructure planning must see the integration of cabling design, clear documentation, and disciplined supervision to avoid the emergence of hidden risks. By putting forward such an issue, this work provides practical guidance for engineers and data center operators who seek to build truly reliable systems by bridging the gap between the theoretical storage architecture and the real-world deployment.
