Using bare metal servers gives businesses the benefits of privately owned hardware together with the benefits of the cloud. Bare metal servers offer up to 50% higher performance than virtualized alternatives, ideal for latency-sensitive applications. To make the most of bare-metal servers, however, it’s vital to set them up properly. With that in mind, here is a step-by-step bare metal server set-up guide.

Selecting the right hardware

The right hardware will depend on your performance requirements, specific considerations (e.g. applications requiring custom hardware), and your budget. Here are five key points to consider when creating your hardware configuration.

CPU and RAM

Evaluate the CPU and RAM based on your application’s demands. Opt for multi-core CPUs with high clock speeds for intensive tasks, and ensure adequate RAM, typically between 16GB and 64GB, to handle workloads efficiently.

Storage solutions

Choose between SSDs for faster data access and HDDs for larger, cost-effective storage. A hybrid approach can offer a balance of speed and capacity, catering to diverse storage needs.

Motherboard

Ensure the motherboard is compatible with your CPU and RAM, with ample slots for future expansions. Verify that it supports necessary interfaces and connectivity options.

Power supply

Select a power supply with sufficient wattage to support current components and potential upgrades. Reliability and efficiency are crucial to maintain server stability.

Cooling systems

Implement effective cooling solutions, such as high-quality fans or liquid cooling, to prevent overheating. Proper cooling ensures optimal performance and longevity of server components.

Assembling the server

The vendor will perform the hands-on aspect of this process. You may, however, need to be available in case they have any questions.

Installing the operating system

The process of installing the operating system on a bare metal server differs from the process of installing the operating system on a server to which you have physical access. Here is an overview of the five key steps.

1. Access cloud management interface

Log into the cloud provider’s management interface where your bare metal server is provisioned. This interface allows you to manage hardware resources and initiate OS installations remotely.

2. Select the server

Navigate to the section where your bare metal servers are listed. Select the specific server you intend to install the operating system on.

3. Choose the operating system

From the available options, select the operating system you wish to install. Cloud interfaces typically offer a variety of OS options like different Linux distributions or Windows Server versions.

4. Configure installation settings

Set up the installation parameters, such as disk partitioning, file system format, and any pre-installation scripts. Customize the configuration according to your needs.

5. Initiate OS installation

Start the OS installation process through the cloud interface. The system will automatically handle the deployment, copying necessary files and setting up the OS on your bare metal server.

Network configuration

Network configuration on a bare metal server is essentially the same as network configuration on any other server. Here are the key steps.

Access cloud management interface

Log into the cloud provider’s management interface where your bare metal server is provisioned. This interface allows you to manage and configure network settings remotely.

Configure network interfaces

Identify the network interfaces available on your server. Assign IP addresses to each interface, typically choosing between static IPs for stable connections or dynamic IPs for flexibility.

Set up DNS

Configure the Domain Name System (DNS) settings. Enter the appropriate DNS server addresses to ensure your server can resolve domain names correctly and communicate effectively with other networked resources.

Configure gateway and routing

Set up the default gateway and routing tables to manage how your server directs network traffic. This ensures proper communication paths for outgoing and incoming data.

Test connectivity

Verify the network configuration by testing connectivity. Use tools like ping, traceroute, or nslookup to ensure that the server can reach external networks and other internal resources.

Implementing security measures

Likewise, implementing security measures on a bare metal server is essentially the same as network configuration on any other server. Here are the key steps.

Configure firewall rules

Set up firewall rules to control incoming and outgoing traffic. Define which ports and protocols are allowed or denied to enhance network security and prevent unauthorized access.

Implement access control

Configure user accounts with appropriate permissions. Use strong passwords and consider implementing multi-factor authentication (MFA) to add an extra layer of security.

Install security software

Deploy antivirus, anti-malware, and intrusion detection/prevention systems (IDS/IPS) to detect and respond to threats. Configure these tools to scan for and block malicious activities.

Harden server settings

Disable unnecessary services and protocols to minimize the server’s attack surface. Configure security settings such as disabling root login via SSH and limiting login attempts.

Monitor and audit

Set up logging and monitoring mechanisms to track server activity. Monitor logs for suspicious behavior and implement regular audits to ensure compliance with security policies.
