Results-driven Storage Administrator with 15+ years of experience in SAN/NAS technologies, specializing in multi-vendor Storage Solutions (Dell EMC, NetApp, HPE, Pure Storage, Infinidat, Hitachi etc.) and Enterprise Fabric Switches (Cisco, Brocade). Proven ability to optimize storage infrastructure, troubleshoot complex issues, and deliver scalable solutions aligned with business needs.

Storage Administration and Management:

• Administered enterprise storage systems including EMC (PowerMax, VMAX, Unity) NetApp (FAS series), HPE (Nimble, 3PAR, Primera, Storeonce), Pure Storage(/C, /X, /XL), and Infinidat etc.
• Provisioned and managed SAN/NAS storage (LUNs, SMB/NFS shares) with thin/thick provisioning, quotas, and tiering policies.
• Performed LUN & Pool Expansion, Controller and Code Upgradation.
• Performed host/LUN/Share reclamation, Server decommissioning, and cluster repurposing.

SAN Fabric & Networking:

• Configured and maintained Cisco MDS/Brocade switches (zoning, ISL, IVR, VSAN/VF and port channel configuration).
• Port Licensing, Fabric isolation and firmware upgradation.
• Troubleshot fabric issues (port flapping, HBA logging failures, C3 discards, CRC errors, slow drain device, port utilization, congestion etc).

Data Replication, Migration & SAN Tech Refresh:

• Design and implement storage replication within Datacentres and between primary and DR sites.
• Managed local/remote replication (EMC SnapVX, Clone, SRDF Sync/Async, Metro & Star, Purestorage snapshot, Active DR, Active Cluster, NetApp snapshot, SnapMirror).
• Executed data migrations via EMC SAN Copy, Open Replicator, NDM (VMAX to PowerMax) and SRDF based migration. Have also been involved in Host-based migrations e.g. Robocopy (windows), rsync & LVM (Linux), Storage vMotion (ESXi), NFS/CIFS Mounts (Unity to Netapp), Commvault (Media Agent).
• Implemented Switch migration as a part of Tech Refresh. Decommissioned old switches and added the new switches into existing fabric in the production environment.

Disaster Recovery, High Availability and Backup Solutions:

• Designed and implemented Disaster Recovery (DR) strategies with RPO/RTO alignment, including storage replication (SAN/NAS), VM-level failover/failback (SRM/vSphere Replication), and application-aware backups (Commvault/Veeam).
• Led DR drills for datacentre and tested application-level failovers and failbacks.
• Managed enterprise backup solutions (Commvault, NetBackup) for disk and tape ensuring data integrity and compliance with retention policies.

Performance Optimization:

• Analyse performance metrics using EMC Unisphere, CloudIQ, Pure1 Meta, HPE Infosight and SSMC, Netapp Active IQ, OnCommand Insight etc.
• Resolved latency/IOPS bottlenecks and tuned array configurations (PowerMax service levels, NetApp QoS etc).

Hardware & Firmware Management:

• Performed hardware replacements (HBAs, SFPs, Cables, PS module, MMC, director, Replication cards, disks and controllers etc).
• Performed Firmware upgrades to Storage arrays and SAN switches.
• Collaborated with vendors to resolve break/fix and critical issues.

Monitoring & Reporting:

• Conducted health checks using CloudIQ, Pure1, HPE Infosight, SANnav, SAN Screen.
• Generated monthly capacity reports and forecasts for proactive planning.
• Have good understanding of Incident & Change Management.
• Used SolarWinds for proactive monitoring and ServiceNow as a ticketing system.

• ITIL V3 Foundation
• Information Storage and Management V3
• AZ-900: Microsoft Azure Fundamentals
