ARM Server

Definition of ARM Server

An ARM server is a type of enterprise-level server that utilizes processors based on the ARM (Advanced RISC Machine) architecture. These servers are known for their energy efficiency, lower heat output, and scalable performance, making them ideal for high-density computing environments. ARM servers have gained popularity in data centers, IoT devices, and cloud infrastructures, serving as an alternative to traditional x86-based servers.


The phonetic pronunciation of the keyword “ARM Server” is:ARM: /ɑːrm/Server: /ˈsɜːrvər/

Key Takeaways

  1. ARM servers operate on a Reduced Instruction Set Computer (RISC) architecture, providing energy-efficient and high-density computing resources compared to traditional x86 servers.
  2. ARM-based servers are well-suited for large-scale data centers, hyperscale cloud environments, and edge computing applications due to their high-performance and low power consumption capabilities.
  3. Many companies, like Amazon Web Services and Microsoft, are increasingly using ARM server technology to support their infrastructure and deliver better overall total cost of ownership (TCO) for their customers.

Importance of ARM Server

ARM server is important in the technology landscape as it represents a shift in server architecture, offering energy-efficient solutions for data centers and cloud computing.

ARM-based servers offer better performance per watt, reducing the overall energy consumption and decreasing costs for the end-users.

Moreover, their scalable and modular design caters to diverse workloads, including edge computing, storage, and machine learning, emphasising the flexibility in meeting market demands.

Popular offerings like Amazon’s Graviton2 and Apple’s M1 chips are proof of ARM’s growing prominence in shaping the future of server and compute technology, driving competition, and facilitating innovation across the industry.


ARM servers, which utilize ARM-based processors instead of traditional x86 architectures, have emerged as a viable solution to meet the ever-growing demands of the modern data center. These servers are designed to provide energy-efficient computing performance, making them especially suitable for scenarios where low power consumption is crucial.

The primary purpose of ARM servers is to offer a cost-effective and power-efficient alternative to conventional server platforms that are predominantly used in applications such as cloud computing, hyperscale data centers, and edge computing environments. With an increasing focus on optimizing data center resources and equipping the Internet of Things (IoT) ecosystem, ARM servers have become significantly popular for delivering substantial power savings without sacrificing compute capabilities.

In addition to their energy efficiency advantages, ARM servers provide more flexibility and customization opportunities for data center providers and enterprises, enabling them to tailor the server hardware to their specific needs. Due to their modular nature and open-source software ecosystem, ARM-based servers can be customized to support a wide range of applications and workloads.

As a result, they have gained traction in several industries and use-cases, ranging from web hosting and content delivery networks to high-performance computing tasks and machine learning workloads. In summary, ARM servers, with their focus on delivering energy-efficient performance and offering greater customization options, have become an increasingly popular choice for organizations aiming to optimize their computing infrastructure and remain competitive in a rapidly evolving technological landscape.

Examples of ARM Server

Amazon Web Services (AWS) Graviton Processors: AWS, a leading cloud provider, introduced its custom ARM-based server processors known as Graviton. These processors have been designed to deliver better performance and energy efficiency for cloud computing workloads. Graviton processors power Amazon’s EC2 instances, like the A1 or the newer M6g, R6g, and C6g instances, that cater to various computing needs like general-purpose workloads, high-performance computing, and memory-intensive applications.

Fujitsu A64FX Supercomputer: Fujitsu, the Japanese multinational information technology equipment and service company, has developed a high-performance computer called Fugaku using ARM-based A64FX chips. Fugaku was ranked the world’s fastest supercomputer in June 2020, showcasing the potential of ARM server technology in high-performance computing. This supercomputer has been deployed for uses like computational drug discovery, climate research, and national defense simulations.

Ampere Altra Processors: Ampere Computing, a company founded by former Intel president Renee James, designs and builds ARM-based server processors targeted at the data center market. The Altra processors boast high core counts and energy-efficient design to cater to the demands of modern hyperscale cloud workloads. These processors are being used in servers built by Lenovo, Wiwynn, and other vendors for tasks like distributed databases, artificial intelligence, and content delivery networks.

ARM Server FAQ

1. What is an ARM Server?

An ARM server is a server system that utilizes the ARM architecture for its CPU. ARM, which stands for Advanced RISC Machine, is a family of low power consumption RISC (Reduced Instruction Set Computer) processors. These processors are commonly found in smartphones, tablets, and embedded devices and have been increasingly used in the server market due to their energy efficiency and high performance.
