# Servers Overview
KH3 Group's server infrastructure is built using a combination of repurposed desktop systems and dedicated network storage devices to meet the organization’s evolving needs. These systems, though originally designed for different purposes, have been strategically adapted to provide essential services, ensuring both flexibility and cost-efficiency in IT operations.

The servers support a variety of critical functions, from network security to hosting enterprise applications and managing data storage. Leveraging virtualization technologies, they maximize resource utilization, allowing for the deployment of multiple virtual machines and services on a single physical system.

KH3’s infrastructure is centered around three main components:

1. **HP 290 G1** - Repurposed as the office firewall, with an enhanced network interface configuration to manage and secure internal and external traffic.
2. **Dell Optiplex 7040** - Serving as a core virtualized host, running Proxmox to deliver essential services like Active Directory, SQL Server, and SharePoint, while also supporting containerized applications.
3. **Synology RackStation RS816** - Acting as the primary storage device, this NAS handles both file synchronization and data backup, ensuring the security of critical organizational data.

Each of these systems plays a vital role in KH3 Group’s operations, providing the necessary infrastructure for secure, reliable, and scalable IT services.



## HP 290 G1 MT
The HP 290 G1 system was acquired by Kh3group in the past, earlier than 2020. The system has been repurposed and is currently serving as the Kh3 office firewall. A PCIe 4-port gigabit Ethernet adapter has been installed, providing a total of 5 network interfaces for the firewall.

## Dell Optiplex 7040 SFF
The Dell Optiplex was acquired in September 2022 to expand KH3's server infrastructure and host additional services. Proxmox VE 7.2-1 is installed on the system, which in turn supports three Windows Server 2016 virtual machines. One VM serves as an active directory domain controller, another runs SQL Server 2016, and the third runs SharePoint Server 2019. Additionally, a Debian LXC container runs on the Proxmox host, with Docker installed to support a variety of additional services containers.
