This curriculum spans the full lifecycle of enterprise storage management, equivalent in scope to a multi-workshop operational readiness program for storage teams in large organisations, covering architecture, provisioning, protection, performance, security, replication, hybrid integration, and decommissioning.

Module 1: Storage Architecture and Tiering Strategies

  • Selecting between block, file, and object storage based on application I/O patterns and data lifecycle requirements.
  • Designing multi-tier storage hierarchies using SSD, SAS, and SATA drives to balance performance and cost.
  • Implementing automated storage tiering policies that migrate data based on access frequency and performance SLAs.
  • Integrating cloud storage tiers with on-premises systems using hybrid storage gateways and caching mechanisms.
  • Evaluating the impact of deduplication and compression on effective storage capacity and application latency.
  • Mapping storage tiers to business-critical applications, ensuring high-performance tiers support transactional databases and virtualization platforms.

Module 2: Storage Provisioning and Capacity Planning

  • Calculating storage overprovisioning ratios for virtualized environments while avoiding thin-provisioning overcommitment risks.
  • Establishing capacity forecasting models using historical growth trends and business project pipelines.
  • Implementing chargeback or showback models to allocate storage costs to departments based on actual usage.
  • Setting up alerts and thresholds for capacity utilization to trigger proactive expansion or cleanup initiatives.
  • Coordinating with application teams to validate storage requests against documented performance and availability needs.
  • Documenting and enforcing storage allocation standards, including naming conventions, mount points, and LUN masking.

Module 3: Data Protection and Backup Integration

  • Aligning backup windows with storage replication schedules to avoid contention on shared storage networks.
  • Configuring snapshot policies with retention periods that comply with regulatory and operational recovery requirements.
  • Integrating storage-level snapshots with backup software to reduce backup window durations and server load.
  • Testing snapshot rollback procedures in non-production environments to validate data consistency and application recovery.
  • Managing snapshot sprawl by enforcing automated expiration and monitoring snapshot storage consumption.
  • Designing backup-to-disk workflows using dedicated storage pools to isolate backup traffic from production workloads.

Module 4: Storage Performance Monitoring and Optimization

  • Deploying storage performance monitoring tools to collect latency, IOPS, and throughput metrics at the array, volume, and host levels.
  • Identifying performance bottlenecks by correlating storage metrics with application response times and VM performance data.
  • Adjusting queue depths, multipathing policies, and HBA settings to optimize end-to-end I/O performance.
  • Conducting periodic storage health checks that include firmware versions, disk error rates, and cache utilization.
  • Right-sizing storage volumes and RAID configurations based on observed workload characteristics and growth projections.
  • Documenting performance baselines and using them to assess the impact of infrastructure changes or new application rollouts.

Module 5: Storage Security and Access Governance

  • Implementing role-based access control (RBAC) for storage arrays to limit configuration changes to authorized personnel.
  • Enforcing zoning and LUN masking in SAN environments to prevent unauthorized host access to storage resources.
  • Encrypting data at rest using array-based or host-based encryption, considering performance and key management implications.
  • Integrating storage audit logs with SIEM systems to detect anomalous access patterns or configuration changes.
  • Managing storage credentials and service accounts according to enterprise password rotation and privilege escalation policies.
  • Conducting periodic access reviews to deprovision storage permissions for decommissioned applications or departed staff.

Module 6: Disaster Recovery and Replication Management

  • Designing synchronous versus asynchronous replication based on RPO and distance between data centers.
  • Validating replication consistency by performing regular failover drills and measuring recovery time.
  • Monitoring replication lag and bandwidth utilization to ensure SLAs are consistently met during peak loads.
  • Documenting and testing storage failback procedures to minimize downtime during primary site restoration.
  • Coordinating replication schedules with maintenance windows to avoid conflicts with backups or firmware updates.
  • Isolating test environments from production replication streams to prevent unintended data overwrites.

Module 7: Cloud and Hybrid Storage Integration

  • Selecting between public cloud storage services (e.g., S3, Blob, EBS) based on durability, access patterns, and egress costs.
  • Implementing cloud tiering policies that move inactive data to lower-cost cloud storage without disrupting applications.
  • Configuring secure connectivity between on-premises storage and cloud providers using private links or IPsec tunnels.
  • Managing data sovereignty by ensuring cloud-stored data resides in geographically compliant regions.
  • Integrating cloud snapshots with on-premises backup workflows to extend recovery options.
  • Monitoring cloud storage usage and API call volumes to detect cost anomalies or unauthorized access.

Module 8: Storage Lifecycle and Decommissioning

  • Establishing data retention policies that align storage lifecycle phases with legal, compliance, and business requirements.
  • Executing secure data sanitization procedures before repurposing or disposing of storage media.
  • Coordinating storage decommissioning with application and database teams to ensure data migration completeness.
  • Updating configuration management databases (CMDB) to reflect retired storage assets and associated dependencies.
  • Reclaiming IP addresses, zoning configurations, and network allocations tied to decommissioned storage systems.
  • Conducting post-decommissioning audits to verify that no orphaned data or access paths remain in the environment.
