6.1.5 Server Preparation

Preparing for working with a node begins with the deployment of the basic software, primarily the operating system. Only one deployment option is discussed below, please contact [e-mail] for other options and for more information.

6.1.5.1 Minimal Requirements

The minimal configuration involves deploying a single node with minimal performance and a limited set of node services.

Parameter	Minimal Requirement	Recommendation
CPU Architecture	X86_64; ARM; s390x;ppc64Ie	X86_64
Number of CPUs	1	2
CPU Performance	1500	2000 bogomips
CPU features	svm|vmx
RAM	4 GB	8GB
Free Disk Space in $HOME	8 GB	30 GB
Internet Access	Required
Virtual Machine		Recommended /VirtualBox
Type of OS		Linux

Regardless of the hardware configuration, the recommended software is presented below in its own minimum configuration:

Parameter	Minimal Requirement	Recommendation
OS Versions	CentOS-7+, Debian-9+, Fedora-32+, LinuxMint-19+, openSUSE-15+, RHEL-7+, Ubuntu-18.04, Ubuntu-20.04+, SLES-15+	Ubuntu 20.04+
Virtualization		Docker 20.10.2+
Tools		Git, Midnight Commander, Postman, Python

6.1.5.2 Deployment Options

You can also consider the following options for deploying a standalone DGT node:

• deploying a single node on a single physical server in a basic configuration.

• installing and configuring a node on a virtual machine (VirtualBox, VMWare, Virtual PC);

• deploying a scalable solution using multiple servers and clustering technology (request [e-mail])

• use a pre-built virtual machine image (Pre-Built Virtual Machine Images);

• cloud host deployment (Digital Oceans; currently in development).
