• Drive proactive performance improvement initiatives

4. Compute Platform Leadership (AIX / Windows / VMware)

• Oversee:

AIX (POWER, LPAR, PowerVC environments)

Windows Server & Active Directory

VMware infrastructure lifecycle (ESXi, vCenter, clusters)

• Support activities including:

OS monitoring, patching, lifecycle management

VM provisioning, decommissioning, and performance tuning.

5. Storage & Backup Architecture

• Design and manage SAN/NAS storage environments
• Optimize storage performance (IOPS, throughput, latency)
• Lead backup/recovery strategy and disaster recovery alignment
• Work with tools like enterprise backup (e.g., Spectrum Protect, etc. based on environment patterns)

6. Network Architecture & Integration

• Define and review:

Data center networking, routing/switching

Connectivity between compute, storage, and application layers

• Work closely with network architects for performance troubleshooting
• Ensure network supports infrastructure scalability and HA needs

7. Monitoring, Automation & Reliability

• Implement and enhance monitoring solutions for infra health, alerts & performance
• Drive automation for:

Provisioning

Capacity reporting

Performance tuning

• Improve observability across infra stack

8. Incident, Problem & Change Management

• Lead resolution of complex L2/L3 infrastructure issues
• Drive root cause analysis for recurring performance issues
• Work within ITIL processes (Incident, Problem, Change)

9. Disaster Recovery & High Availability

• Design DR/HA solutions for critical infrastructure
• Ensure infrastructure readiness for failover scenarios
• Periodically validate DR drills

Required Skills & Experience

Core Technical Skills

• Compute

IBM AIX (LPAR, Power systems, PowerVC)
