Viglen HX420Gi HPC GPU Compute Node
2 Teraflops of floating point performance in 1U of rack space!

The Viglen HX420Gi is the world’s first and only GPU optimised 1U server, featuring multiple x16 nonblocking native Gen2 PCI-Express connectivity slots to the GPU, a highly reliable thermal optimization, and industry-leading power efficiency.

 
Key Features
Performance
The HX420Gi design architecture provides direct PCI Express 2.0 x16 non-blocking connectivity to each GPU to take advantage of the GPUs full bandwidth. No extra cabling is required, since the GPUs are connected directly to the server motherboard via riser cards, thus improving reliability, airflow, and maintenance, as well as reducing costs.
Advanced System Management
The advanced IPMI capability allows the GPU system to be managed directly by via remote monitor and controlling functions. All the key elements of the server system - CPU, GPU and power supply - are remotely monitored from the extensive onboard IPMI management and control subsystem.
Highly Reliable Thermal Optimisation
The Viglen HX420Gi's advanced thermal subsystem designs optimise the cooling elements of the server with the thermal characteristics of the GPU, CPU, motherboard, and other components. The cooling system is designed to protect against any single point of fan failures, enhancing system reliability and simplifying maintenance. In addition, by monitoring both CPU and GPU thermal readings through the I2C bus, the HX420Gi's unique intelligent cooling control and auto fan-speed adjustment keep the entire system operating smoothly.
Industry-Lead PowerEfficiency
The HX420Gi features Gold Level (93% efficiency) power subsystems, along with high efficiency motherboard and thermal designs to delivery breakthrough performance per watt and increased system reliability.
