A Top of Rack (ToR) design typically requires more switches because each rack has its own switch to
manage network connections, as opposed to End of Row (EoR) or centralized designs, which
consolidate switches. While ToR designs improve cabling efficiency and reduce latency, they also
increase the number of switches, thus raising management complexity and potentially increasing
capital and operational costs.
Detailed Explanation:
In a ToR setup, each rack’s individual switch allows for quick access and streamlined cabling within
the rack. However, this setup means more devices to configure, monitor, and maintain, which can
increase administrative overhead and network management complexity.
EPI Data Center Specialist Reference:
EPI documentation notes that ToR designs can improve performance but also lead to increased
management needs due to the higher switch count, making them less ideal in environments where
simplified network management is prioritized.
