General Introduction & Requirements for Installing ARO Client

ARO Client Introduction

The ARO Network is a permissionless Edge Cloud designed to leverage diverse resources. To support this, ARO provides a software image (the ARO Client) that can be installed on various devices.

Note that the ARO Client is geared toward advanced users, requiring greater technical expertise from both the device and the operator.

Recommended Requirements for Software Clients (ARO Client)

General Requirements that are strongly recommended for all ARO Client Software (especially for operators with business-level bandwidth):

• Static IP & Public IP
• NAT Type: Full Cone NAT or higher (e.g., NAT0, DMZ NAT1, UPnP NAT1)
• Do NOT install software image in VM
• CPU Clock Speed: ≥ 2 GHz
• Disk:
  • SSD with NVMe protocol
  • Random 4K Read IOPS ≥ 30,000

Port Requirements for all ARO Client Software:

• TCP: 80, 443, 9500-9700
• UDP: All ports

Hardware Specifications Requirements for running ARO Client based on your bandwidth. If your bandwidth falls between the listed values, you can estimate the requirements by interpolating linearly.

Bandwidth	CPU threads	RAM	System Disk	Data Disk	Network Card
100 Mbps	≥ 4	≥ 4 GB	≥ 50 GB SSD	≥ 200 GB SSD	100 Mbps
500 Mbps	≥ 8	≥ 12 GB	≥ 100 GB SSD	≥ 500 GB SSD	1 Gbps
1 Gbps	≥ 16	≥ 16 GB	≥ 200 GB SSD	≥ 1 TB SSD	10 Gbps
5 Gbps	≥ 48	≥ 64 GB	≥ 200 GB SSD	≥ 5 TB SSD	10 Gbps
10 Gbps	≥ 96	≥ 128 GB	≥ 200 GB SSD	≥ 10 TB SSD	10 Gbps
20 Gbps	≥ 192	≥ 256 GB	≥ 200 GB SSD	≥ 20 TB SSD	10 Gbps * 2

ARO Client Installation - General Guide & Important Notes

IMPORTANT - Read Before Install:

• The ARO Client software image currently supports only x86 architecture. Do NOT attempt to run the ARO Client on ARM or other alternative architectures.
• Running the ARO Client in a virtual machine (VM) environment is NOT supported.
• To install the ARO Client, a bare-metal machine running a Debian operating system (Version 11 or higher) is required as a prerequisite.

General Steps to Follow:

1. If you do not have Debian installed, refer to Operating System Tutorial guide.
2. If you are ready with the operating system, refer to Installation & Initialization Tutorial for ARO Client.
3. Install PCDN Client (refer to PCDN Worker Installation Tutorial) to enable edge service capabilities for your ARO Client.

Special Notes for VM Installations (Legacy)

IMPORTANT - If you are running a VM-based installation of ARO Client:

• The VM-based installation is deprecated and no longer supported due to performance limitations, particularly for commercial edge services.

• If you are currently using a VM-based installation of the ARO Client (e.g., from the Previewnet phase when VM installations were supported), we strongly recommend migrating to the new installation method as soon as possible.
