Drut PRU 2500 High-Density PCIe Gen5 Chassis
Transforming Resource Management
The Photonic Resource Unit (PRU) 2500 is a high-density, high-performance PCIe Gen 5-based resource chassis that sets a new standard for data center architecture. Designed for businesses that demand more from their infrastructure. Whether you’re running AI workloads, HPC applications, or financial computing tasks, the PRU 2500 delivers unparalleled density, efficiency, and flexibility.
Key features include:
- Support for up to 12 PCIe devices: Supports up to 10 double-width GPUs per PRU 2500.
- Integration with FIC 2500: Holds up to four Fabric Interface Cards.
- Bandwidth: Over 1 Tbps per slot, enabling GPU-to-GPU memory sharing.
- GPU Flexibility:
- Support for multi-vendor and multi-generation accelerators (GPUs).
- Hot-swapping of devices.
- Dynamic attach/detach capabilities for real-time resource management.
