In the Lab: GRAID SupremeRAID™ on Corespan's Photonic PCIe Fabric

A direct, evidence-first field note: GRAID SupremeRAID™ running GPU-accelerated RAID 6 parity over Corespan's photonic PCIe fabric — 43 GB/s read bandwidth, 117 µs p99.99 latency, zero PCIe errors.

Rent or Buy? Why the Corespan PRU 2500 with RTX 5090s Is the Right First Step Toward an Owned AI Fleet

An honest rent-vs-buy analysis of RTX 5090 GPUs on June 2026 market data. See why owning the Corespan PRU 2500 beats every production-grade rental tier.

Why the PRU 2500 With RTX 5090s Is the Smartest Inference Node You Can Buy Right Now

A 4× RTX 5090 PRU 2500 out-throughputs a fully optimized H100 SXM on Qwen-32B FP8 — at roughly one-tenth the cost per million tokens. The numbers, and why the chassis matters.

Corespan PRU 2500 with 8x RTX 5090 vs. an 8x B200 HGX Server

A practical capex, TCO, throughput, and utilization comparison of a Corespan PRU 2500 with 8x RTX 5090 GPUs versus an 8x B200 HGX server.
