Case Study: Colovore achieves 35 kW-per-rack high-density cooling and a 1.1 PUE with Vertiv's Liebert DCD rack-door solution

Colovore - Customer Case Study

Colovore, a Santa Clara–based colocation provider for high-performance computing (HPC), faced the challenge of supporting increasingly power-hungry GPU and AI servers in a land-constrained Silicon Valley market. To meet high-density cooling and space-efficiency needs, Colovore worked with Vertiv and deployed Vertiv’s Liebert DCD rack door cooling modules (alongside other Vertiv infrastructure) to deliver the thermal management required for next‑generation workloads.

Vertiv’s solution—several hundred IT racks fitted with Liebert DCD rear-door modules and complementary Vertiv power and monitoring systems—enabled Colovore to support up to 35 kW per rack, achieve DGX-Ready certification, host nearly 1,000 DGX platforms, and run fully packed top-to-bottom racks with no unusable U slots. The deployment reduced required cabinets and floor space, lowered operating costs passed to customers, and produced measurable efficiency gains (PUE as low as 1.1 at 50% load), with Vertiv continuing as Colovore’s standardized partner.
