ANDREW LARTEY

• Lead the end-to-end administration, capacity planning, and performance tuning of enterprise NetApp ONTAP and block/file storage arrays supporting mission-critical database workloads • Architect high-availability SAN fabric topologies (Cisco/Brocade) and automate storage provisioning using Ansible and Python APIs to accelerate volume allocation and LUN mapping. • Manage enterprise backup and disaster recovery operations (Veeam/NetBackup), optimizing backup windows by 35% and guaranteeing air-gapped protection for database and VM estates. Orchestrate hardware lifecycle updates, firmware patching schedules, and vendor management across storage nodes to ensure zero-downtime operations. • Automate compliance evidencing (ISO 27001, DORA, NIS2) using Infrastructure as Code (Ansible), embedding continuous security and compliance into the platform lifecycle.

• Managed global enterprise storage assets across 30 data centers, standardizing storage catalogs, provisioning workflows, and data protection policies. • Implemented strict RPO/RTO storage availability baselines, health checks, and non-disruptive maintenance protocols for hybrid Linux and Windows storage pools. • Coordinated routine business continuity and disaster recovery failover testing across multi-site data center environments. • Engineered automated runbooks for infrastructure provisioning and cutover, significantly reducing manual deployment steps and ensuring reliable system scaling. • Maintained accurate technical documentation and led knowledge-sharing initiatives across multi-regional operational teams during service transitions.

• Administered 5PB+ enterprise storage array estate (NetApp ONTAP, EMC UNITY/VMAX) in a highly regulated banking environment, achieving 100% data availability and RPO/RTO targets. • Developed Python scripts to automate data protection policies, backup verification, and reporting across Oracle, MSSQL, MySQL, and VMware workloads. • Engineered cyber-resilient data protection using NetApp SnapMirror/SnapVault, immutable backups, and isolated recovery vaults to defend against ransomware. • Participated in incident response and problem resolution for storage outages, conducting rigorous Root Cause Analysis (RCA) to prevent recurrence. • Produced comprehensive Low-Level Designs (LLDs) and operational documentation to facilitate knowledge transfer across the engineering team.

• Supported high-availability broadcast storage infrastructure for BBC playout operations, ensuring strict SLOs (99.99% availability) were met for Linux and media-based workloads. • Collaborated with platform and vendor teams to troubleshoot complex storage issues, validating solutions against technical acceptance criteria.

• Led backup platform modernization, defining data protection service levels (RPO/RTO) for large-scale virtualized and database environments. • Managed infrastructure troubleshooting, change management, and incident escalation in a highly regulated production environment.

• Managed a 5PB+ storage estate, leading a strategic infrastructure review that generated £6M in savings while maintaining system reliability for 25,000+ users. • Executed large-scale data centre consolidation, migrating 600+ Linux, Unix, and Windows servers from 16 legacy arrays to 4 modern NetApp/EMC systems with zero data loss. • Conducted performance benchmarking and platform selection (NetApp vs. EMC Isilon) to determine optimal file and object storage solutions for engineering teams.
