Dedicated Sui RPC Node Servers

A dedicated Sui node server provides isolated, high-performance infrastructure specifically optimized for Sui blockchain operations. Unlike shared solutions, you get exclusive hardware resources, custom configurations, and ultra-fast response times ideal for advanced Web3 applications.

When compared to shared and public hosting options, a dedicated server may have a higher starting cost. However, dedicated servers offer superior performance and capability for Sui RPC and validator nodes because of two unique advantages. 

• You can customize the hardware from the start. This means you can select the best hardware combination (CPU, RAM, storage, network bandwidth) for optimal performance.
• Server security can be completely customized for your project’s specific requirements. 

We recommend the following hardware specifications for a dedicated Sui node server:

• A high-performance, multi-core processor
• At least 128 GB of RAM
• 2 x 3.84TB NVMe enterprise drives. 
• A reliable and high-speed internet connection with a minimum upload speed of 10 Gbps

At RedSwitches, we provide the optimized bare-metal infrastructure and expertise to help you deploy and maintain high-performance Sui nodes for RPC operations or validator participation.

Let’s start with a quick look at the suggested hardware for a Sui node:

CPU: 24 cores or more (AMD EPYC preferred)

RAM: 256GB ECC DDR4

Storage: Minimum 4TB NVMe SSD for ledger data

Connectivity: Stable, high-speed link with a bandwidth of 1Gbps to 100Gbps

Recommended OS:

We recommend Ubuntu (22.04 LTS or the latest stable version) or similar Linux distributions.

Process Overview

When setting up a Sui node, you have the option to either use the Docker image or build directly from the source code. We suggest building from source code because it allows you to benefit from the latest improvements in code.

Prepare Your Server

Starting from a clean server, update the packages to make sure you have a solid foundation for the Sui node. Next, install the required dependencies for the Sui node software. Since the software is written in Rust, you should make sure you have the latest version of Rust on the server.  

Create a New User

Create a new sui user that you will use for interacting with the node. For this, we strongly recommend granting this user sudo privileges for ease of operations. 

Download the Binaries

At this point, you should set up the required directory structure for the node. This involves creating the main directory and files. Next, use the wget command to download the desired version of the Sui binaries.

Install the Software

Use cargo to build and install the node software. Before running the command, make sure you have the required keys and Sui CLI with keytool installed on the system. 

Performance and Security Tips from RedSwitches

• Always download binaries from the official repositories. This simple step helps you avoid issues created by outdated (and malicious) code from third-party sources. 

• Test before you deploy to production. This is especially crucial when you are updating existing node software. Untested software may bring down active nodes. 

• Server security is an ongoing activity. Regularly review firewall rules to verify that important ports are protected from unauthorized access.
