The network bandwidth plays a crucial role in determining the performance of a data center or a computing power center. Network bandwidth, usually measured in megabits per second (Mbps), refers to the data transfer rate of a network. More bandwidth means data moves faster.

Calculating Servers and Bandwidth Requirements

Here is the formula to calculate the number of servers and bandwidth requirements:

Network bandwidth (Mbps) = Number of servers / 150

For instance, if a computing power center is running 3,000 servers, the upstream and downstream bandwidth of enterprise broadband should not be less than 20Mbps.

Types of Broadband

There are two types of broadband:

  1. Dedicated Line: In this type of broadband, the upstream and downstream bandwidth are equal. For example, if there’s a 100M dedicated line, both upstream and downstream are 100M. According to the formula, a dedicated line of this capacity can handle about 15,000 machines.
  2. Ordinary Household Broadband: In this type of broadband, the uplink is generally 1/10 of the downlink. For instance, a 500M broadband for home use means that the theoretical downlink rate is 500Mbps, while the theoretical upload rate is around 50Mbps. Based on this, the actual number of machines that it can handle is about 7,500 units.

Understanding the bandwidth and load capacity of a network can help you make informed decisions when setting up and managing a data center or computing power center.
