Question 1

What is GPU colocation and how does it differ from cloud rental?

Accepted Answer

GPU colocation means placing your own GPU hardware in a third-party data center providing power, cooling, networking, and physical security. Unlike cloud rental where you pay per-hour for shared resources, colocation gives you dedicated hardware at fixed monthly cost, typically 40-60% cheaper for sustained workloads over 6 months.

Question 2

What power density do GPU clusters require for colocation?

Accepted Answer

Modern GPU clusters require 20-100+ kW per rack depending on configuration. A single NVIDIA DGX H100 system draws approximately 10 kW. Data centers offering GPU colocation must provide high-density power, direct liquid cooling or rear-door heat exchangers, and sufficient cooling capacity per rack.

Question 3

What interconnect options are available for colocated GPU clusters?

Accepted Answer

High-performance GPU colocation facilities offer InfiniBand NDR (400 Gbps) for training clusters, RDMA over Converged Ethernet for flexible deployments, and high-bandwidth spine-leaf network architectures. GYGO helps match your interconnect needs with facilities that support your cluster topology.

Question 4

How much does GPU colocation cost per month?

Accepted Answer

GPU colocation pricing typically ranges from $500-2,000 per kW per month depending on location, power density, cooling type, and contract length. A standard 40 kW GPU rack costs $2,000-8,000/month. This is significantly cheaper than equivalent cloud GPU rental for workloads running continuously.
