  • Storage Integration: Configure and maintain NAS/SAN storage systems to support high-performance virtualized workloads and data integrity.

3. Resilience, Security & Disaster Recovery

  • High Availability (HA): Monitor and maintain failover clustering and HA configurations to prevent single points of failure.

  • Backup & DR Strategy: Implement and rigorously test disaster recovery plans, ensuring system backups are reliable and recovery time objectives (RTOs) are met.
