The Corespan Mercury Rack — a vendor-neutral composable rack platform with 72 double-wide PCIe Gen5 GPU slots, up to 1.2PB of composable NVMe per PRU 2500, and up to 111 kW of rack power.

The Mercury Rack: One Rack, Every GPU, Yours to Compose

72 double-wide PCIe Gen5 slots, any vendor's accelerators, 1.2 PB of composable NVMe per PRU, and 111 kW in a standard air-cooled 48U rack. The Mercury Rack makes the compute-to-storage ratio a scheduling decision instead of a purchasing one.

Frontier Intelligence on Gaming Silicon: Why the PRU 2500 Turns RTX 5090 Fleets into Real AI Infrastructure

Kimi K3 running on 80× RTX 5090s proved a frontier open model no longer needs HBM. The harder problem is turning 80 gaming cards into a production service — composed, cooled, and orchestrated. That is what the PRU 2500 is for.

Corespan Systems + Foqum: Building the Sovereign AI Stack Europe Has Been Waiting For

Corespan’s composable photonic infrastructure meets Foqum’s ISO 27001-certified AI platform — giving European enterprises high-performance AI on hardware they own, govern, and audit.

Why the PRU 2500 Wins Twice: Once on Capex, Again on Financing

The GPU that wins the spec sheet rarely wins the term sheet. See how the Corespan PRU 2500 cuts both capex and financing cost on a $3.5M build.

From Trophy to Utility: Why the Next Era of AI Infrastructure Belongs to Composability

The GPU has been a trophy for three years. That era is ending. Corespan on why composable, photonic infrastructure is the only substrate that turns compute into a true utility — and what changes for operators who get there first.
