Virtual Machine Hypervisor Host Cluster Upgrade & Maintenance
Maintained hypervisor cluster security and performance by performing rolling OS upgrades and firmware patches across physical host nodes.
Key Features & Implementation
- Live Workload Migration: Migrated active virtual machines sequentially off target hosts using Live Migration without interrupting user connections.
- Cluster-Aware Updating (CAU): Orchestrated CAU automated patch windows ensuring at least N+1 host redundancy remained active throughout updates.
- Post-Maintenance Host Validation: Verified host CPU, RAM, and SAN storage multipathing stability before returning hosts to the active cluster.
