Harvester
Harvester es una plataforma de infraestructura hiperconvergente que combina computación, almacenamiento y redes en un único sistema para gestionar entornos virtualizados en servidores bare metal. Funciona como una plataforma de gestión de virtualización y gestor de hipervisor KVM, proporcionando una interfaz centralizada para orquestar el ciclo de vida completo de las máquinas virtuales.
El proyecto se distingue por integrar el almacenamiento en bloques distribuido Longhorn para ofrecer almacenamiento redundante definido por software, además de una herramienta de aprovisionamiento bare metal para despliegues automatizados. Esto permite orquestar la infraestructura en servidores físicos mediante arranque PXE, iPXE y UEFI HTTP.
Las capacidades de la plataforma incluyen la orquestación de máquinas virtuales con migración en vivo y aprovisionamiento cloud-init, así como recuperación ante desastres empresarial mediante snapshots y copias de seguridad remotas. También abarca la configuración de redes virtuales para VLANs e IPs virtuales, junto con herramientas integrales de instalación del sistema para la asignación de roles de nodo y la ejecución de comandos post-instalación.
Features
- Hyperconverged Infrastructure Management - Implements a hyperconverged infrastructure that unifies compute, storage, and networking into a single managed system on bare metal.
- Hyperconverged Infrastructure Platforms - Combines compute, storage, and networking into a single software-defined system for managing virtualized environments on bare metal.
- Block Storage - Integrates Longhorn to provide redundant and scalable distributed block storage for virtual machines.
- Distributed Volume Management - Provides capabilities to create, clone, and export distributed storage volumes using direct attached storage and tiering.
- Software-Defined Architectures - Implements software-defined storage by managing block storage volumes and physical disks for virtualized workloads.
- Block Storage Services - Integrates Longhorn to provide redundant, distributed block storage services as persistent volumes for virtual machines.
- Bare Metal Orchestration - Automates the installation of operating systems on physical hardware using PXE, iPXE, and UEFI HTTP booting.
- Hyperconverged Infrastructure Software - Provides a platform combining compute, storage, and networking into a single system for managing virtualized environments on bare metal.
- Virtual Machine Lifecycle Management - Provides a centralized interface for handling machine lifecycles, live migrations, and virtual networking.
- Virtual Machine Managers - Enables creating, editing, cloning, and deleting virtual machines with support for cloud-init and SSH-key injection.
- Orchestration - Manages the full lifecycle of virtual machines, including creation, live migration, and cloud-init configuration.
- QEMU KVM - Uses a KVM-based hypervisor to manage virtual machine lifecycles and resource allocation on bare metal servers.
- Cloud-Init Configurations - Provides a mechanism to inject custom configuration data and SSH keys into virtual machines during their first boot process.
- Storage Provisioning - Allows designating physical volumes or disk paths to serve as the default storage for virtual machine data.
- Unattended Operating System Installations - Allows skipping interactive setup steps by retrieving configuration from a URL or kernel parameters during installation.
- Cluster Role Assignment - Allows specifying whether a node functions as a management, worker, or witness node during the installation process.
- Network Configuration - Enables defining host network interfaces using static or DHCP IP assignment, bonding modes, and VLAN IDs.
- Network Booting Utilities - Automates system installation by loading boot images and configurations over the network using PXE and iPXE.
- UEFI HTTP Booting - Supports loading boot images directly from an HTTP server using UEFI firmware to initiate system installation.
- Virtual Network Management - Provides configuration for virtual networks, including VLANs and virtual IPs, to connect virtual machines to external networks.
- Live Migrations - Enables moving running virtual machines between physical hosts without stopping the guest or interrupting service.
- Virtual Machine Backup - Provides disaster recovery capabilities through the creation and restoration of virtual machine snapshots to remote storage.
- Backup & Disaster Recovery - Supports enterprise disaster recovery through the creation and restoration of virtual machine snapshots to remote storage.
