NA255A-G4

Performance Desktop PCIe 4.0 ×16 (256Gbps) upstream port PCI Express expansion chassis particularly designed for multiple GPU cards (up to 4× triple-width PCIe Gen4 slots available)

Overview

The PCIe Gen4 ×16 – 256Gbps Ultra High Speed Bandwidth to Create The Ultra High Performance GPUs to Computing & HPC Workflows

The Netstor NA255A-G4 GPU chassis implements the latest ultra high-speed PCIe 4.0 technology and PCIe Gen4 16-lane host interface with 16Gbps throughput per lane totally offering blazing-fast data transfer rates up to 256Gbps between host server/computer and expansion enclosure, dedicated for high-performance GPU-accelerated applications.

256Gbps

Up to

2xbandwidth

Supports up to Four GPU Cards with Each Graphics card within Netstor unit given PCIe 4.0 ×16 signal for Highest Bandwidth

The GPU chassis is created to have four PCIe 4.0 ×16 slots (×16 electrically) on NA255A-G4 backplane, supporting up to four triple-width/dual-width PCIe Gen4 GPU cards, or single-width third-party PCIe cards. Additionally, the enclosure can accommodate all combinations of PCIe 4.0 ×16, ×8, ×4, and ×1 GPU/PCIe cards for every application with backward compatibility for Gen3 cards to work with server/workstation in various fields like HPC, telecom, data centers, and many more.

Each GPU card is ensured to have supplementary PCIe 8-pin cables from PSU in support of Operation and High-End GPU Application

Dedicated high watt power supply for GPU Application

Newest high-end or enthusiast GPU cards generally require high power wattage for work; in light of the hi-power requirement factors, Netstor has thoughtfully planned a dedicated, high-efficient and high watt power supply unit within the GPU chassis to allow up to four high-performance graphics cards to process and render at the same time with highest reliability and stability.

Supplementary 6+2 pin PCI-E Power Cables

Netstor NA255A-G4 GPU chassis has been considerately created to provide extra PCIe 6+2 pin power cables to meet each GPU card’s supplementary power requirement; therefore, no matter which graphics card that comes with any combination of 6-pin/8-pin PCIe power connectors is fully supported by Netstor unit.

Extra Graphics Card Holder

In view of high-performance GPU card with length up to 32 cm or so, due to card's heavy weight, wider width, and longer length, special graphics card holder has been considerately designed to support each PCIe ×16 slot within NA255A-G4 chassis in favor of holding the heavy-weight GPU card firmly and reliably in support of running multiple high-end graphics cards within the unit continuously.

Ultra Fine Airflow Warm Air Dissipation Design with Adjustable Variable Fan Speeds

NA255A-G4 is equipped with two front large 12×12 cm cooling fan modules with each fan supporting 106 CFM maximum flow, providing best airflow ventilation to chassis for most excellent heat dissipation while ensuring GPU cards within chassis can continuously operate long time without any high temp concern. Additionally, the fan speed of each cooling fan can be manually adjusted according to GPUs’ application situation within Netstor unit.

Considerate Ventilation Framework

Although Netstor GPU chassis does support triple-width GPU cards, as double-width graphics card is utilized within enclosure, even better heat dissipation will be achieved for the graphics card within because wider gap between cards will be attained for the even finer airflow.

Unlimited GPU Acceleration Rendering Solutions

Conventional server just has CPU and integrated GPU to deal with professional applications; nevertheless, these processors couldn't even provide powerful enough computational rendering to satisfy present-day processing requirement. As a result, through the adding of NA255A-G4 GPU chassis with up to four enthusiast graphics cards to server can simply make it a supercomputing workstation.

8K DaVinci Resolve Configuration

NA255A-G4 provides complete solution in favor of working with latest 8K UHD DaVinci Resolve resolution, the world's most advanced color grading application software; the Netstor GPU chassis also provides high-performance processing to server/workstation in support of colorist team/studios in the digital content creation field, being the best ever solution in favor of real-time, 8K/6K Ultra HD color correction.

Healthcare Organizations

Medical imaging takes the advantage of multi-GPU computation to get acceleration. Common use case in medical imaging covers accelerating Advanced MRI Reconstruction and Computed Tomography Reconstruction. The utilization of multiple graphics cards with NA255A-G4 GPU chassis in this field is common and there have been many related applications in the area.

General Analytics

Specialists can use tools like MATLAB, LabView, Mathematica, and many more through the utilization of multiple graphics cards in NA255A-G4 chassis in favor of accelerating the numerical analytics computation. Reliable statistics have demonstrated that computation capability of multiple GPUs is more than ten times faster than CPU alone.

AI, Machine Learning, and Deep Learning

Increasing number of data scientists uses multiple graphics cards in GPU chassis for large data analytics to make better and real-time business decisions. Typical application case in big data analytics includes machine learning, deep learning, search, sorting, and many more.
