Exploring the Benefits of Data Center Fabric

Posted on Jun 16, 2023

The increasing demand for data processing and storage has led to the need for more agile, scalable, and flexible data centers. Traditional data center architecture has faced challenges in terms of agility, scalability, and flexibility. The need for a more modular and flexible data center architecture has led to the rise of data center fabric. In this article, we will explore the concept of data center fabric, its benefits, and how to deploy it using FS switches.

Current Problems in Traditional Data Center Architecture

The data center fabric is designed to be more flexible, scalable, and agile than traditional data center architecture, making it a more favored choice for data center network architecture. Traditional data center architecture, based on the three-tier model, has several disadvantages that have led to the adoption of data center fabric. The data center tier 3 architecture is rigid and inflexible, making it difficult to adapt to changing business needs. This can limit the ability to innovate and integrate new technologies into the data center. The following are the main problems with traditional hierarchical data center networks:

  • Limited scalability: The capacity and throughput of core layer switches in traditional data center networks are limited, and there are certain limitations in scale expansion.

  • Network latency and bottlenecks: In traditional hierarchical interconnection networks, multi-hop forwarding of data packets incurs high network latency and may cause bottleneck problems.

  • Management complexity: Traditional architecture requires complex configuration and management, and as the scale of data centers increases, higher requirements will be placed on network administrators.

  • Inefficient traffic engineering: The traditional network has some shortcomings in traffic engineering, which can not make full use of network resources to achieve load balancing and optimize performance, affecting the overall network throughput and efficiency.

  • Difficult failure recovery: In data center architecture, failure recovery may require recomputation and path forwarding by multiple network devices, resulting in longer recovery time and more difficult troubleshooting and localization.

With the continuous development of cloud computing technology, the advantages of data center fabric will be more and more prominent, because it can provide more efficient, more flexible, more secure, more efficient cloud computing services, so as to better meet the needs of users.

What is Data Center Fabric and How Does It Work?

Data center fabric is a new approach to data center networking that is based on the concept of a fabric, which is a mesh of interconnected switches. It is a network of leaf and spine switches that collectively represent a resilient and scalable infrastructure providing connectivity between software entities installed on servers. CLOS and POD are two common approaches to data center fabric.

What Do You Know About CLOS and POD?

CLOS and POD play a great advantage in data center fabric. CLOS is a network topology that uses multiple layers of switches to create a mesh network. This approach provides high scalability, fault tolerance, and load balancing. POD is a modular approach to data center fabric that uses self-contained units called pods. Each pod contains servers, storage, networking, and power and cooling infrastructure. Pods can be deployed and managed independently, making them more agile and flexible than traditional data center architecture. CLOS and POD provide a more flexible and scalable approach to data center fabric.

The Application Advantages of CLOS and POD

CLOS and POD are designed to be more resilient, with redundant links and switches to minimize downtime. They can be designed to use standard hardware and software, making them easier to maintain and integrate with new technologies.


The Benefits of Data Center Fabric

Data center fabrics have several advantages that make them the preferred solution for modern data center networks:

  • Scalability: It adopts a flat topology that allows direct communication between any two nodes in the data center, avoiding the bottleneck problem of the core layer in the traditional hierarchical network.

  • Low latency and High bandwidth: The flat architecture of data center fabric reduces the number of hops a packet takes through the network, thus reducing network latency. At the same time, it uses high-speed connection and multi-path design to provide greater bandwidth and throughput to meet the needs of high-performance applications.

  • Simplify management: Data center fabric separates the network control plane from the data forwarding plane, enabling centralized network management and control.

  • High reliability and fast failure recovery: Data center fabric employs redundant paths and fast failure detection mechanisms to quickly recalculate and forward traffic in the event of failure, enabling fast failure recovery and high availability.


Deploying Data Center Fabric by Using FS Switches

FS data center fabric network solution uses CLOS networking architecture, combined with the whole network IP three layer forwarding, to build a modular data center Internal Fabric network (IDC). It uses N series data center switches at the spine and leaf layer, which can support 10G/25G/100G server and storage access. At the core layer, it builds a 40G/100G high-speed interconnection network through modular switches. FS switches are designed to be easy to install and manage, making them an excellent choice for deploying data center fabric.
