Design Overview

Data Center Basic Layered Design of Core, Aggregation, and Access.

The design of data center networks follows a well-established layered approach, refined through extensive testing and enhancement in some of the world’s most extensive data center deployments over recent years. This layered approach forms the fundamental framework of data center design solutions, aiming to enhance scalability, performance, flexibility, resilience, and maintenance. The diagram illustrates the foundational layered design.

Key Features

The data center network is segmented into three standardized three-layer structures.

The layering primarily revolves around the concept of internal and external traffic flow. In the data center network, there are three standard layers: core, aggregation, and access. The majority of traffic between servers and business systems remains within a single functional zone, bypassing the core layer. Inter-zone traffic, however, traverses the core layer, making it more practical and effective to implement mutual access control strategies on the aggregation layer switches of each zone. This approach alleviates pressure on the core, reduces fault scope, and facilitates faster fault recovery.

The core layer facilitates interconnection.

The core layer enables the interconnection of numerous data center aggregation modules and links to the campus network core. It necessitates robust switching capabilities and the ability to handle burst traffic effectively. Large data center cores demand expansion capabilities across multiple aggregation modules, while small and medium-sized data centers typically utilize the campus core. Presently, it predominantly employs 10GE interfaces, with high performance necessitating 4-8 10GE bundles..

The aggregation layer offers high-bandwidth connectivity.

The aggregation layer furnishes high-bandwidth export for server farms, necessitating high-density GE/10GE ports for access layer interconnection. It boasts additional slots for deploying value-added service modules. Common industry practice involves integrating various security and application optimization services at the aggregation layer, such as incorporating firewalls, load balancing, and application acceleration boards onto switches.

The access layer facilitates high-density access.

The access layer accommodates high-density Gigabit and 10 Gigabit access, with convergence ratios and line speed modes for total access and uplink bandwidth. With rack considerations in mind, the 1RU offers greater flexibility in deployment, supporting stacking and enhanced expansion capabilities, along with dual-link redundancy for uplinks.The access layer is designed to ensure seamless scalability and redundancy for efficient network operations.
