Summary

This wiki contains the design, architecture, implementation, and deployment plans for setting up a Private Compute Cluster using OpenStack, Ceph, KVM, QEMU, and SDNs. It is intended for managing and deploying virtualized environments with high availability, performance, and scalability.

The Private Compute Cluster setup provides a robust solution for managing and orchestrating virtual machines (VMs) and storage. It leverages OpenStack for orchestration, Ceph for scalable storage, KVM/QEMU for virtualization, and Software-Defined Networking (SDN) for network management.

This wiki includes:

Architectural designs and configurations for the setup.
Step-by-step implementation instructions.
A deployment plan for setting up and managing the entire cluster.

Design Documentation

This section provides detailed design documentation, including a breakdown of the cluster components, their interactions, and the overall setup strategy. This documentation is essential for understanding the rationale behind the architecture choices and ensuring smooth deployment.

Architecture Design

The architecture is based on the following components:

OpenStack for cloud infrastructure management.
Ceph for scalable and fault-tolerant storage solutions.
KVM/QEMU for virtualization and managing VMs.
SDNs for flexible and efficient network management.

The cluster is designed to be highly available, scalable, and fault-tolerant, providing a flexible infrastructure for a wide range of use cases.

Implementation

This section covers the steps required to implement the private compute cluster:

Installation and configuration of OpenStack.
Setup of Ceph storage for VM and data management.
Deployment of KVM/QEMU for virtual machine management.
Configuration of SDN for network isolation and performance optimization.

Deployment Plan

The deployment plan provides detailed instructions for deploying each component in the cluster.
