As data center traffic grows, the need for high-performance data center fabrics becomes more important. A data center fabric is a high-speed, low-latency computer network that connects computer systems and devices in a data center. A fabric-based architecture is intended to provide a more efficient and scalable alternative to legacy, hierarchical architectures, where systems are connected through a series of point-to-point links. There are several ways to optimize your data center fabric for performance. Keep reading to learn more.

Data Center Fabric

A data center fabric is a network of switches that connects servers and storage devices in a data center. The fabric allows the devices to communicate with each other, providing high performance and scalability. The most important factor in achieving good performance from a data center fabric is the design of the network. The fabric should be configured for optimal performance based on the specific needs of the data center. Consider the number of devices, their location within the data center, and the type of traffic they will generate. Once the design is complete, it’s essential to verify that it’s implemented correctly. Tools such as packet sniffers can help identify any problems with the network configuration.

Size Your Fabric Correctly

The first step in optimizing your data center fabric for performance is sizing your fabric correctly. When you size your fabric, you need to consider the number of devices connected to it, the traffic patterns between those devices, and the amount of bandwidth required for each connection.

You also need to consider the type of devices that will be connected to the fabric. For example, if you are connecting switches and servers, you will need higher bandwidth than connecting only switches.

Once you have determined the appropriate bandwidth requirements for each connection, use these calculations to size your fabric:

  • For a single device, multiply the required bandwidth by two.
  • For two devices, add the required bandwidths together.
  • For three or more devices, multiply the required bandwidth by three.
  • For full-duplex connections, double the calculated value.

Optimize Your Data Center Fabric for Performance


You will need to follow a few simple steps to optimize your data center fabric for performance.

Identify your network traffic patterns and determine which applications generate the most traffic. Once you have identified the high-traffic applications, you can begin to optimize their performance by using the appropriate networking technologies.

Consolidate your servers and storage into as few clusters as possible to minimize network latency. You should also use fast storage devices such as solid-state drives (SSDs) and 10 Gigabit Ethernet (10 GbE) adapters whenever possible.

Use quality of service (QoS) features on your switches to ensure that important applications receive the bandwidth they need. QoS can be used to guarantee bandwidth for specific applications, or you can use it to limit the bandwidth available to specific applications. This can be helpful if some applications are causing congestion on the network.

Use proper cabling infrastructure in your data center to reduce cable length and attenuation. For example, Cat6A cabling is ideal for 10 GbE networks because it has a higher transmission speed and more resistance to interference than other types of cabling.

Install adequate power and cooling systems in your data center so that all of your equipment can run at its optimal temperature. Overheating can cause servers and switches to fail, so it’s important to ensure that your data center is well ventilated and adequately cooled.

Test everything. Once you have implemented all these changes, test them thoroughly before putting them into production. This will help ensure that everything works correctly and that your new configuration has no unexpected problems.

Overall, optimizing your data center fabric for performance is key to ensuring that your applications and data are delivered promptly and safely. Data center fabrics can help you identify and address any bottlenecks in your network, resulting in a more efficient and effective data center.
