  🏗️ The Core of Efficient Resource Distribution: Mastering HA Groups In a virtualization environment, simply turning on 'High Availability (HA)' is not enough. You need a detailed #strategy to determine which virtual machine should run on which node with priority and where it should move in the event of a failure. The 'HA Group' in Proxmox VE acts as a control tower that logically groups nodes within a cluster to control the movement path of services. In this #lecture , we will take an in-depth look at how to create and activate HA groups at the Datacenter level to maximize resource efficiency. 1. Concept and Purpose of HA Groups HA groups are essential when not all nodes have the same performance or when specific services are dependent on specific hardware. A. Logical Node Filtering An HA group is a #system that defines a set of nodes within the cluster where a specific VM or CT can run. This prevents critical services from moving to nodes with lower hardware speci...

  🏎️ A High-Speed Highway for Seamless Service, Dedicated Migration Network The most common bottleneck when running a Proxmox VE cluster and performing Live Migration is the network. The process of transferring dozens of gigabytes of memory data all at once can collide with existing service traffic, causing service latency or even migration failure. In this #lecture , we will take an in-depth look at the 'Migration Network Isolation' strategy, which can maximize cluster stability and revolutionarily increase transfer speeds. Optimize your infrastructure to the next level through this successful #method . 1. Decisive Reasons Why Network Isolation is Necessary Why should we build a dedicated line for migration separately from the management or service networks? A. Blocking Interference with Service Traffic Live Migration tends to occupy all available network bandwidth. If this bandwidth is shared with the service network used by users, it can cause the service to slow down or te...
