Networking in Data Centers


Server network connectivity is a critical aspect of modern data center operations, serving as the backbone that supports extensive data processing, storage, and transfer activities. High-speed connections facilitate real-time data access and transfer, enabling data centers to support the growing need for compute.

By integrating innovative network connectivity solutions, data center builders can achieve their goals to:

  • Get online faster

  • Improve uptime reliability

  • Maximize space and energy use

  • Find efficiencies in install and support

Efficient cabling, robust switches, and innovative connector solutions are vital for establishing a network infrastructure that can adapt to evolving requirements and increasing workloads of today and challenges of tomorrow.

Miniaturized Data Connections

Transfer robust amounts of data and increasingly faster speeds, without taking extra space. 

Today's data center networks are being asked to transmit data at lightning speed and within less physical area. Unlike legacy connectors, HARTING data transfer connectivity components help make it possible to meet the challenges of today and the requirements of tomorrow.

Next-Gen ix Industrial®

✓ Built with size in mind
✓ Supports Cat. 6A performance for speeds up to 1/10 Gbit/s
✓ Power over Ethernet (PoE) capabilities for more functionality in less space
✓ 70% smaller than the RJ45 connector

HARTING ix Industrial® with 70 % smaller device socket

Tecnologie Varioboot & Dualboot nelle Patch costampate primo livello.png

Varioboot for Data Center Networking

Compact, agile, and cost-effective RJ45.

The HARTING Varioboot is a standard RJ45 overmolded patch cable with the unique ability to adjust the orientation and angle of the connector. This simplifies cable routing in tight locations, such as crowded control cabinets and/or tight electrical enclosures.

✓ Pull, snap, turn, twist, cable and connector based on application needs
✓ Over 20 possible orientations for unparalleled flexibility
✓ Reliability to deliver up to 10 GB/s data transmission
