Critical Virtual Machine Assurance

{{ $t('productDocDetail.updateTime') }}: 2025-12-17

Based on the business criticality, configure assurance for critical virtual machines. This primarily includes designations such as critical VM labeling, large page memory allocation, and storage policy guarantees.

Critical Virtual Machine Assurance provides the following capabilities:

Memory Assurance: Disables memory reclamation mechanisms to prioritize and guarantee memory availability, enhancing business performance.

Storage Assurance: Prioritizes data reconstruction in the event of a failure. During data rebalancing, it prioritizes moving data from other VMs first. It is recommended to select a high-performance storage policy to ensure optimal performance.

Continuity Assurance: In the event of a physical host failure, prioritizes the restart of these VMs to minimize service interruption time. When a physical host experiences resource constraints, it prioritizes migrating other VMs to free up resources for critical VMs, ensuring stable business operation.
