15+ Years of Enterprise Infrastructure Design, Modernization & Campus Revamps

Challenge

• Rapid organizational growth requiring multi-floor and multi-campus expansion
• High-density engineering environment demanding stable, low-latency infrastructure
• Need for distributed rack architecture across floors
• Large-scale structured cabling (5,000+ nodes in later phases)
• Lifecycle refresh of aging infrastructure (1G → 10G/40G migration)
• Post-acquisition revamp of a newly built campus executed by another vendor
• Requirement for zero-disruption live network migration

Solution

• Designed distributed campus architecture with localized floor racks and fiber backbone
• Implemented fully redundant Layer 3 core with Cisco switching ecosystem
• Deployed multimode 24-core fiber backbone across racks
• Engineered structured cabling with uniform rack discipline and labeling
• Executed enterprise-wide refresh using Cisco C9300 (access) and C9500 (core)
• Migrated uplinks from 1G to 10G/40G with fiber breakout architecture
• Re-engineered VLAN segmentation and redundancy models
• Delivered complete BOQ, CAT6A cabling design, smart rack architecture, and data center layout for Sophos House 2 revamp

Implementation

• Step 1: Initial enterprise setup at CG Road (2008–2010) with Cisco 2960X access switching and structured cabling across multiple floors
• Step 2: Cyberoam House 1 deployment (2011) – 27 racks, multimode 24-core fiber backbone, Cisco 3850 core, ~80–90 switches, ~50–60 APs, ~100 CCTV cameras, strict VLAN segmentation
• Step 3: Enterprise-wide technology refresh (2019) – Cisco C9300 access, C9500 core, 10G/40G uplink migration, structured cabling redesign
• Step 4: Sophos House 2 audit and redesign (2019–2024) – 27+ APC racks, 6 two-post racks, 5,000+ nodes, CAT6A deployment, full data center + office network architecture
• Step 5: Live migration, stabilization, and compliance validation without operational downtime

Tech Stack

• Network: Cisco 2960X, 3850, C9300 (access); Cisco C9500 (core)
• Security: VLAN-based segmentation, management VLANs, server VLAN isolation
• Wireless: Controller-based Cisco wireless (multi-floor deployment)
• Monitoring / Tools: Structured rack discipline, LIUs, fiber backbone management, APC rack systems, CAT6A structured cabling
