Every GPU Loan is Also a Topology Loan

Software portability lets a workload move across silicon. Hardware composability lets the silicon move across workloads. A lender's recovery scenario needs both.

The Commodity Optical Switch Thesis: Why the Moat in Photonic Infrastructure Is the Control Plane

The optical switch will be essential, but essential does not mean differentiated. The durable value in photonic infrastructure sits in the control plane — the software that composes heterogeneous fleets into one adaptable system.

Scale-Across: The Architecture the Inference Era Actually Needs

The inference era is being scored on the wrong metric. Scale-across composes GPUs, memory, and I/O per workload — then reclaims it — so operators stop paying peak-case prices for average-case demand.

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.

Rent vs. own three-year TCO comparison for an 80× RTX 5090 Corespan PRU fleet.

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.
