Teraco, an interconnection hub and vendor-neutral data centre provider, has completed its JB4 Bredell Campus data centre expansion located in Ekurhuleni, east of Johannesburg, South Africa.
The 30MW addition expands JB4 to being the largest standalone data centre built in Africa, servicing 50MW of critical IT power load.
According to Jan Hnizdo, Teraco CEO, “Teraco is dedicated to expanding its capacity across key hubs, ensuring our clients have the flexibility to scale and fully leverage digital transformation across the region. We continue to make significant investments in ICT infrastructure and have established Africa’s largest data centre platform. We are proud to offer open-access interconnection and deliver world-class data centre solutions to all our clients.”
This new phase at JB4 comprises six data halls, incorporates numerous new design enhancements and, in another African first, each hall supports 5MW of allocated critical IT power load. The new data halls are fully liquid-to-liquid cooling enabled, allowing clients to deploy high-density, air-cooled cloud deployments and direct-to-chip cooling for denser AI workloads.
JB4 has been designed with sustainability at its core, incorporating a state-of-the-art closed-loop chilled water system that provides free air cooling, coupled with AI enabled technology to configure data hall cooling in real time, based on IT load and load dispersion.
The JB4 expansion, built to stringent global hyperscale specifications, contributes significantly to the South African and sub-Saharan African data centre footprint. This follows the recent completion of Teraco’s new hyperscale JB5 Isando facility, which adds another 30MW of critical IT power load to Teraco’s Isando Campus in Ekurhuleni.
The JB4 facility is located in the heart of Ekurhuleni’s Aerotropolis giving access to a wide choice of network service providers, regional IXPs, content delivery networks, cloud service provider on-ramps, and peering at the eighth largest internet exchange in the world, NAPAfrica.
Teraco’s growing data centre platform stands at 189MW of critical power load which includes the Isando Campus (JB1/JB3/JB5: 70MW), Bredell Campus (JB2/JB4: 64MW), Cape Town Campus (CT1/CT2: 53MW), and Durban (DB1: 2MW).
The JB4 is the largest standalone data centre built in Africa with 80 000m2 of building structure, serviced by 80MW of utility power supply, providing 50MW of critical IT power load
JB4 features environmentally conscious designs including a zero-water closed loop cooling system and specialised monitoring technology to improve energy efficiency.
The total facility comprises 14 data halls, making up 17 000m2 and is the first data centre in Africa to provide 5MW of critical IT load within a single data hall.
