Designing a Resilient, Multi-Gigabit Network Infrastructure for a Leading Healthcare Provider

Executive Summary

A premier healthcare institution embarked on a significant expansion with the construction of a new building. This growth necessitated a robust, scalable, and highly reliable network infrastructure to support critical services like Electronic Medical Records (EMR), medical imaging, IP telephony, CCTV surveillance, and high-speed guest Wi-Fi. The challenge was to integrate the new facility with the existing IT ecosystem while eliminating single points of failure and ensuring maximum uptime.


ACENET TECHNOLOGIES was commissioned to design and implement an end-to-end networking solution, including structured cabling, core and edge switching, wireless access, and server cluster optimization. This case study outlines the challenges, solutions, and outcomes of this comprehensive project.

The Challenge: Scalability, Performance, and High Availability

The project presented several critical challenges

Infrastructure Scalability

The new building required over 600 data points (CAT6/CAT6A) for computers, IP phones, and medical devices, with a need for future expansion.

Performance Demands

Medical applications and data storage required a high-speed backbone, necessitating 10Gigabit and multi-gigabit capabilities between core switches and the server farm.

Network Segmentation & Security

Separate, secure VLANs were needed for sensitive patient data, administrative systems, IP phones, CCTV cameras, and public guest Wi-Fi, all centrally secured by a next-generation firewall.

Maximum Uptime

The network core and server infrastructure required redundancy to ensure no single point of failure could impact critical healthcare operations.

Seamless Integration

The new network had to be seamlessly interconnected with the existing building's infrastructure via a robust fiber optic link.

The ACENET Solution: A Layered, Redundant Architecture

We implemented a future-proof, multi-layered solution designed for performance and resilience.

1. Structured Cabling and Physical Infrastructure
  • Installed 445+ wall-mounted CAT6/CAT6A keystone jacks throughout the new building.
  • Implemented an ESPG (Elevated Static Pressure Plenum) raised floor system to organize cable pathways.
  • Deployed three dedicated server/switch racks:
    • 37U DATA Rack for computer and server connections (CAT6A)
    • 37U IP-Phone Rack with PoE+ switches
    • 37U CCTV Rack with PoE+ switches for surveillance cameras
2. High-Performance Core and Edge Networking
  • Core Switching: Deployed redundant TP-Link TL-SX3016F 10G SFP Multi-Gigabit core switches in both buildings.
  • Edge Switching: Installed a suite of TP-Link managed switches:
    • 11x TP-Link TL-SG3428X (10G SFP+)
    • 6x TP-Link TL-SG3428XMP (PoE+) for IP Phones
    • 8x TP-Link TL-SG3428XMP (PoE+) for CCTV
  • Security: Inter-VLAN routing and policies enforced by a high-availability SonicWall NSA 3700 firewall pair.
3. Secure Segmentation via VLANs
  • Data VLANs: 172.31.16.0/24, 18.0/24, 19.0/24
  • CCTV VLANs: 172.31.15.0/24, 17.0/24
  • IP Phone VLAN: 172.31.20.0/24
  • Wi-Fi VLANs: 172.31.21.0/24 (Staff) and 172.31.166.0/24 (Guest)
4. Campus Connectivity
  • Inter-connected the old and new buildings with a 150-meter, 12-core single-mode fiber cable, terminated in LIU panels.
5. Enterprise-Grade Wireless
  • Installed 6x TP-Link Omada EAP660 HD Wi-Fi 6 access points across all floors, managed centrally for seamless roaming.
6. Hyper-V Server Cluster Optimization
  • NIC Teaming: LACP teams on primary & secondary Hyper-V servers, 20 Gbps bandwidth with redundancy.
  • Failover Clustering: NIC Teaming + Windows Server Failover Clustering for transparent failover.
  • Dedicated Networks: Separate networks for Heartbeat and Live Migration for performance and stability.

The Result: A Future-Proof Foundation for Healthcare IT

The implementation of this sophisticated network infrastructure delivered significant benefits:

Enhanced Reliability

The redundant core, server clustering, and NIC teaming have effectively eliminated single points of failure, ensuring near-100% uptime for critical healthcare applications.

Superior Performance

The 10G/multi-gigabit backbone and Wi-Fi 6 wireless network provide the bandwidth necessary for data-intensive medical applications, improving responsiveness and user experience.

Robust Security

Centralized firewall policies and logical network segmentation protect sensitive patient data and isolate key systems like CCTV and guest Wi-Fi.

Improved Scalability

The structured cabling and modular switch design allow for easy expansion to support future growth and technology adoption.

Streamlined Management

Centralized management via the Omada controller and standardized configurations simplify ongoing network administration and troubleshooting.
