Raspberry Pi enthusiast Jeff Geerling has streamed a video this week to commemorate Raspberry Pi day 2021 showing how you can connect 16 hard drives to a single Raspberry Pi Compute 4 module or similar. This impressive feat demonstrates the versatility and power of the Raspberry Pi platform, particularly for those interested in creating a robust and scalable storage solution. Check out the video below to see the process and learn more about some of the pitfalls and problems you may encounter as you set up your own extended storage system perfect for a Raspberry Pi NAS or similar.
Understanding the Raspberry Pi Compute Module 4
The Raspberry Pi Compute Module 4 (CM4) is a powerful and compact computing solution designed for deeply embedded applications. It incorporates a quad-core ARM Cortex-A72 processor, dual video output, and a wide selection of other interfaces. Available in 32 variants, the CM4 offers a range of RAM and eMMC Flash options, and comes with or without wireless connectivity. This flexibility makes it an ideal choice for a variety of projects, from simple DIY setups to more complex industrial applications.
One of the key features of the CM4 is its ability to handle multiple peripherals and interfaces, which is crucial when connecting numerous hard drives. The module’s PCIe interface, in particular, allows for the addition of high-speed storage controllers, enabling the connection of multiple hard drives. This makes the CM4 a perfect candidate for building a Network Attached Storage (NAS) system, which can be used for personal or small business data storage needs.
Building Your Own Raspberry Pi NAS
Creating a NAS system using the Raspberry Pi Compute Module 4 involves several steps and considerations. First, you need to choose the right hardware components. In addition to the CM4, you’ll need a carrier board that supports the module and provides the necessary interfaces for connecting hard drives. There are several third-party carrier boards available that offer various features, such as additional USB ports, SATA connectors, and power management options.
Once you have the hardware, the next step is to set up the software. The Raspberry Pi OS is a popular choice for this purpose, as it provides a stable and user-friendly environment. You’ll need to install the operating system on the CM4 and configure it to recognize and manage the connected hard drives. This may involve installing additional software packages, such as Samba for file sharing or OpenMediaVault for a more comprehensive NAS solution.
It’s important to consider the power requirements of your setup, especially when connecting multiple hard drives. Each drive will require a certain amount of power, and the total power consumption can add up quickly. Make sure to use a power supply that can handle the combined load of the CM4 and all connected drives. Additionally, proper cooling is essential to prevent overheating, which can lead to hardware failure and data loss.
The Raspberry Pi Compute 4 is now available to purchase directly from the Raspberry Pi online store and resellers worldwide. This accessibility makes it easier than ever for enthusiasts and professionals alike to experiment with and deploy powerful computing solutions.
The Raspberry Pi Compute Module 4 offers a versatile and powerful platform for building a variety of projects, including a robust NAS system. By understanding the capabilities of the CM4 and carefully planning your hardware and software setup, you can create a scalable and efficient storage solution that meets your needs. Whether you’re a hobbyist looking to expand your Raspberry Pi projects or a professional seeking a cost-effective storage solution, the CM4 provides the flexibility and performance required for success.
