What are Mini-Computers?

Mini-computers, also known as mid-range computers or departmental servers, are a type of computer system that are designed to bridge the gap between personal computers and mainframes in terms of processing power and capabilities.

They typically have more memory and storage capacity than personal computers, and are capable of handling a greater number of simultaneous users or processes. Mini-computers are typically used in small to medium-sized businesses, organizations, and specific departments within larger companies.

One of the key features of mini-computers is their ability to function as multi-user systems, allowing multiple users to access and share the same system resources. This makes them a popular choice for use in office environments, where a number of employees need to access shared files, databases, or other information.

Additionally, mini-computers often include built-in security features, such as hardware-based security controllers, which help to protect the system and its data from unauthorized access. Some other features of mini-computers may include advanced networking capabilities, the ability to support virtualization technologies and the ability to run various operating systems.

All of these factors together make mini-computers a versatile and powerful option for businesses and organizations looking for a cost-effective and scalable computing solution.

How to build a Network of Mini-Computers?

Building a network of mini-computers, also known as a cluster, involves several steps. Here is a general overview of the process:

How to build a Network of Mini-Computers?
  • Gather the necessary hardware: You will need a number of mini-computers (such as Raspberry Pi), along with ethernet cables and a router to connect them.
  • Assemble the hardware: Connect the mini-computers to the router using the ethernet cables. Make sure that each mini-computer has a unique IP address.
  • Install an operating system: Install a Linux-based operating system on each mini-computer. This is typically done by writing an image of the OS to an SD card and then inserting the card into the mini-computer.
  • Configure the network: Configure the network settings on each mini-computer to allow for communication between the devices. This typically involves setting up a hostname, and configuring the network interfaces.
  • Install cluster management software: Cluster management software allows you to manage and monitor the mini-computers in your network. Popular choices include OpenMPI, Rocks Cluster, and LSF.
  • Set up the software environment: Install and configure any necessary software and libraries on each mini-computer.
  • Test the cluster: Once everything is set up, test the cluster by running a simple job on it to ensure that everything is working properly.

Six Advantages of Mini-Computers

Mini-computers, also known as single-board computers, have several advantages over traditional desktops or laptops. Here are six main advantages:

  • Cost-effective: Mini-computers are much more affordable than traditional computers, making them a cost-effective solution for a wide range of applications.
  • Low power consumption: Mini-computers consume less power than traditional computers, making them a great choice for applications where power is a concern, such as remote sensing or mobile applications.
  • Small form factor: Mini-computers are much smaller in size than traditional computers, making them easy to deploy and use in a wide range of settings, including remote locations, industrial environments, and vehicles.
  • Versatility: Mini-computers can be used for a wide range of applications, including embedded systems, Internet of Things (IoT) devices, and even as a full-fledged desktop computer.
  • Customizable: Mini-computers are highly customizable, allowing you to add new hardware and software to meet the specific needs of your application.
  • Scalability: Mini-computers are highly scalable, you can cluster them together to form a supercomputer and they can also be combined with other hardware, such as sensors or cameras, to create powerful, highly-integrated systems.

Six Disadvantages of Mini-Computers

While mini-computers have many advantages, they also have some disadvantages to consider

  • Limited processing power: Mini-computers typically have less processing power than traditional computers, which can make them unsuitable for certain types of applications that require a lot of computational power, such as video rendering or scientific simulations.
  • Limited storage capacity: Mini-computers usually have less storage space than traditional computers, which can be an issue for applications that require large amounts of data, such as machine learning or big data analysis.
  • Limited connectivity: Mini-computers typically have fewer connectivity options than traditional computers, which can be an issue for applications that require a lot of input/output, such as cameras, sensors, or other devices.
  • Limited upgradability: Mini-computers have a limited upgradability as compared to traditional computers, which means you cannot upgrade the hardware or software as easily. This makes it difficult to keep up with the latest technologies.
  • Limited cooling: Mini-computers can have a limited cooling capacity, which can be a problem in certain applications where the computer generates a lot of heat, such as high-performance computing.
  • Limited support: Mini-computers can have limited support, which means you may have to rely on online communities for troubleshooting or support. This can be an issue if you need immediate assistance or if you are not technically proficient.

Conclusion

All in all, the small-size mini-computer have great abilities and advantages, like an excellent ratio of performance and price, high configuration and various operating systems for personal computers. They have been widely used in many fields, no matter it is education and learning, gaming, office work or other scenes. And they are with a good development prospect and will become more popular in the coming years.
