Datacenter Management Course

Lesson 1 • Logical Infrastructure Overview

Introduces virtualisation, software-defined networking, and cloud integration concepts. Bridges physical hardware knowledge to logical resource management.

Lesson 2 • Physical Infrastructure Components

Surveys servers, storage, networking hardware, and supporting physical systems. Provides the hardware literacy needed for all subsequent management topics.

Lesson 3 • Datacenter Documentation Standards

Covers asset registers, network diagrams, and change logs as operational necessities. Accurate documentation underpins every management discipline in the course.

Lesson 4 • Datacenter Roles and Industry Context

Defines the datacenter's function within enterprise IT and business continuity. Sets the professional context for all subsequent technical and operational content.

Lesson 1 • Power Distribution Units and Rack Power

Examines PDU types, branch circuit monitoring, and per-outlet metering at the rack level. Enables precise capacity planning and overload prevention.

Lesson 2 • Generator and Backup Power Systems

Details diesel and natural-gas generator sizing, transfer switching, and fuel management. Ensures continuity of power during extended utility outages.

Lesson 3 • Utility Power and Distribution Architecture

Explains utility feeds, switchgear, and main distribution panels in datacenter contexts. Establishes the upstream power path that all downstream systems depend on.

Lesson 4 • Power Usage Effectiveness and Efficiency

Introduces PUE measurement, benchmarking, and improvement strategies for operational efficiency. Directly links power management to cost reduction and sustainability goals.

Lesson 1 • Airflow Management and Hot-Cold Aisle Design

Covers hot-aisle and cold-aisle containment, blanking panels, and raised-floor airflow. Proper airflow management reduces cooling energy and prevents hot spots.

Lesson 2 • Computer Room Air Conditioning Systems

Explains CRAC and CRAH unit operation, placement, and capacity sizing. These units form the primary cooling layer in most traditional datacenter designs.

Lesson 3 • Liquid and Immersion Cooling Technologies

Introduces rear-door heat exchangers, direct liquid cooling, and immersion cooling for high-density racks. Prepares students for next-generation thermal management challenges.

Lesson 4 • Cooling Efficiency Metrics and Optimisation

Covers cooling efficiency ratio, water usage effectiveness, and optimisation techniques. Links thermal management performance to operational cost and sustainability targets.

Lesson 1 • Network Redundancy and High Availability

Details link aggregation, spanning tree alternatives, and multi-path routing for resilience. Redundancy design prevents single points of failure in critical network paths.

Lesson 2 • Switching, Routing, and VLANs

Covers Layer 2 switching, Layer 3 routing, and VLAN segmentation within the datacenter. Proper segmentation improves security, performance, and traffic isolation.

Lesson 3 • Datacenter Network Topology Design

Examines spine-leaf, three-tier, and fat-tree topologies for scalability and redundancy. Topology choice directly affects latency, bandwidth, and fault isolation.

Lesson 4 • Network Performance Monitoring and Troubleshooting

Introduces traffic analysis tools, latency measurement, and systematic fault isolation methods. Monitoring skills enable proactive issue detection before service impact occurs.

Lesson 1 • Storage Architecture Fundamentals

Compares DAS, NAS, and SAN architectures across performance, scalability, and cost dimensions. Establishes the storage vocabulary and design logic used throughout the chapter.

Lesson 2 • Storage Performance Optimisation

Examines tiering, caching, deduplication, and compression for maximising storage efficiency. Performance tuning reduces cost per usable terabyte and improves application response.

Lesson 3 • Data Lifecycle and Retention Management

Covers data classification, archival policies, and secure deletion aligned with retention requirements. Lifecycle management controls storage growth and reduces compliance risk.

Lesson 4 • Storage Networking and Protocols

Details Fibre Channel, iSCSI, and NVMe-oF protocols for connecting storage to compute. Protocol selection affects latency, throughput, and infrastructure complexity.

Lesson 1 • Regulatory Compliance Frameworks

Surveys major compliance frameworks for data protection, financial controls, and critical infrastructure. Compliance requirements shape security policies and audit readiness activities.

Lesson 2 • Network Security Architecture

Details firewall placement, intrusion detection systems, and network segmentation for defence in depth. Security architecture must align with the network topology established earlier.

Lesson 3 • Logical Access Control and Identity Management

Explains role-based access control, multi-factor authentication, and privileged access management. Logical controls prevent unauthorised access to systems and sensitive data.

Lesson 4 • Physical Security Controls and Design

Covers perimeter barriers, access control systems, CCTV, and mantrap design for physical protection. Physical security is the first defence layer for all datacenter assets.

Lesson 1 • Log Management and Event Correlation

Explains centralised log aggregation, SIEM integration, and event correlation for operational insight. Log analysis connects security monitoring with performance and availability management.

Lesson 2 • DCIM Platform Deployment and Use

Covers DCIM software capabilities, data integration, capacity modelling, and workflow automation. DCIM centralises visibility across power, cooling, space, and network assets.

Lesson 3 • Infrastructure as Code and Configuration Automation

Introduces IaC principles, configuration management tools, and automated provisioning pipelines. Automation reduces human error and accelerates consistent infrastructure deployment.

Lesson 4 • Capacity Planning and Predictive Analytics

Covers trend analysis, growth modelling, and predictive alerting for proactive capacity management. Data-driven forecasting prevents resource exhaustion and supports budget planning.

Lesson 1 • Disaster Recovery Plan Development

Guides creation of DR plan documents including runbooks, contact trees, and escalation paths. A well-structured plan enables consistent execution under high-stress conditions.

Lesson 2 • Recovery Objectives and Strategy Design

Defines RTO, RPO, and recovery tier strategies aligned with business impact findings. Strategy selection balances recovery speed against infrastructure investment.

Lesson 3 • DR Testing, Exercises, and Continuous Improvement

Covers tabletop exercises, failover drills, and full simulation tests with structured after-action reviews. Regular testing validates plan effectiveness and drives iterative improvement.

Lesson 4 • Backup Technologies and Replication Methods

Examines backup types, replication modes, and offsite data protection technologies. Backup and replication are the technical mechanisms that achieve defined RPO targets.
