AI in Transnistria: A Server Configuration Overview
This article details the server configuration used to support Artificial Intelligence (AI) initiatives within Transnistria. This document is aimed at newcomers to the Transnistrian server infrastructure and provides a technical overview of the hardware, software, and networking components involved. It is crucial to understand these specifications for maintaining, troubleshooting, and potentially expanding these systems. This configuration is designed for research and development, focusing on areas like Computer Vision, Natural Language Processing, and Machine Learning.
Overview
The AI infrastructure in Transnistria is currently centralized in a single, heavily fortified data center located near Tiraspol. Due to geopolitical factors and limited access to international markets, the configuration relies heavily on repurposed hardware and open-source software solutions. The goal is to create a robust, albeit constrained, environment for AI experimentation and potential application in areas like Agricultural Optimization, Security Systems, and Data Analysis. The system is heavily reliant on Redundancy principles, given the potential for disruptions. Security is paramount, involving strict Access Control and continuous Vulnerability Scanning.
Hardware Configuration
The core compute power is distributed across a cluster of servers. The following table details the specifications of the primary compute nodes:
| Server Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon E5-2690 v4 (2.6 GHz, 14 cores) | 8 |
| RAM | 128 GB DDR4 ECC Registered | 8 |
| Storage (OS/Boot) | 512 GB NVMe SSD | 8 |
| Storage (Data) | 8 TB HDD (RAID 6) | 4 x 4TB Arrays |
| GPU | NVIDIA GeForce RTX 3090 (24 GB GDDR6X) | 4 |
| Network Interface | 10 Gigabit Ethernet | 8 |
These servers are housed in standard 19-inch racks, utilizing redundant power supplies and liquid cooling to manage heat output. A separate cluster of less powerful servers handles data preprocessing and storage, detailed below. The entire system is backed up by a robust Uninterruptible Power Supply (UPS) array capable of providing several hours of operation during power outages.
Software Stack
The software stack is built around a Linux distribution, specifically Ubuntu Server 22.04 LTS. This provides a stable and well-supported base for the AI development environment. Key software components include:
- Operating System: Ubuntu Server 22.04 LTS
- Containerization: Docker and Kubernetes are used for application deployment and scalability.
- Programming Languages: Python is the primary language, with support for R and C++.
- Machine Learning Frameworks: TensorFlow, PyTorch, and Scikit-learn are the main frameworks.
- Database: PostgreSQL serves as the primary database for storing data and model metadata.
- Version Control: Git and GitHub are used for code management and collaboration.

Networking and Security
The AI infrastructure is isolated from the public internet and connected to the Transnistrian internal network via a dedicated VLAN. Strict firewall rules, managed by iptables, govern all network traffic. The following table outlines the key networking components:
| Component | Specification |
|---|---|
| Firewall | Custom iptables configuration |
| Router | Cisco Catalyst 2960-X |
| Switch | HP Aruba 2930F |
| VLAN | Dedicated VLAN for AI infrastructure (VLAN 10) |
| DNS | Internal DNS server (Bind9) |
Security is further enhanced through regular Penetration Testing and intrusion detection systems. All data is encrypted at rest and in transit using TLS/SSL. Access to the servers is restricted to authorized personnel with multi-factor authentication.
Data Storage Cluster
A separate cluster of servers is dedicated to data storage and preprocessing. These servers have larger storage capacities but less powerful compute capabilities.
| Server Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon E3-1220 v3 (3.1 GHz, 4 cores) | 4 |
| RAM | 64 GB DDR3 ECC Registered | 4 |
| Storage | 16 TB HDD (RAID 6) | 2 x 8TB Arrays |
| Network Interface | 1 Gigabit Ethernet | 4 |
This cluster utilizes a distributed file system, Ceph, to provide scalable and fault-tolerant storage. Data is regularly backed up to offline tape storage for disaster recovery purposes. The data storage is integrated with Data Lakes for efficient data management.
Future Expansion
Future expansion plans include upgrading the GPU cluster with newer generation hardware (pending availability) and expanding the storage capacity of the data storage cluster. Exploration of federated learning techniques is also underway to allow for collaboration with other research institutions. Improvements to the Network Monitoring system are also planned to enhance system visibility and proactive maintenance.
