Introduction to Data Center: Top of Rack (ToR) Architecture Design
Source: Cisco Systems
This paper provides a look at the use of top-of-rack (ToR) cabling and switching model for next-generation data center infrastructure. The paper explores current 10G cabling choices and provides solution architecture based on ToR to address architecture challenges. Data center managers and facilities folks will choose cabling architectures based on various factors. The ToR model offers a clear access layer migration path to an optimized high-bandwidth network and cabling facilities architecture that features low capital and operating expenses and supports a rack-and-roll computer deployment model that increases business agility. The data center's access layer, or Equipment Distribution Area (EDA), presents the biggest challenge to managers as they choose a cabling architecture to support the data center computer connectivity needs.
