Netstor NA265A-XGPU-S Elite Rackmount GPU Enclosure



Elite Rackmount GPU Enclosure

NA265A is a professional-grade 19" rackmount GPU enclosure that works perfectly with host PC, server or workstation. Through the adding of the rackmountable NA265A GPU expansion enclosure, even the space-limited 1U or 2U server can be transformed into a high-performing workstation or supercomputing for the modern ultra fast processing center.

128Gbps Bandwidth PCIe Gen3 x16

The Netstor NA265A GPU enclosure implements the latest PCIe 3.0 technology and PCIe Gen3 16-lane host interface with throughput 8Gbps per lane, offering blazing-fast data transfer rates up to 128Gbps between host and expansion enclosure, dedicated for GPU-accelerated applications.

Up to 4 Dual-Width GPU Cards

The GPU enclosure is designed to have 4 PCIe x16 slots (x8 electrical)1 on NA265A backplane supporting up to 4 double-width PCIe Gen3 GPU cards, or single-slot PCIe cards. In addition, the enclosure can accommodate all combinations of PCIe 3.0 1, 4, 8 and 16 GPU/PCIe cards for every application with backward compatibility for Gen2 cards to work with host, server or workstation in areas such as HPC, telecom, and data centers.

Great Sufficient Powering

  • 1200 WPSU
  • 80 PLUSGold
  • 6+2 pinPCI-E cables

Dedicated Single 1200W or Redundant 1350W PSU

Newest high-end or enthusiast GPU cards generally require high power wattage for work; in light of the hi-power requirement condition, Netstor has considerately planned a dedicated, high-efficient single 1200W PSU in NA265A GPU enclosure to allow up to 4 high-performing graphics cards for processing, or a redundant 1350W PSU in rackmount enclosure to allow NA265A to be deployed at cabinet room with ultimate reliability and stability.

Supplementary 6+2 pin PCI-E Power Cables

Netstor NA265A GPU enclosure has been thoughtfully designed to provide extra PCI-E power cables to meet each GPU card's supplementary power requirement. Furthermore, any combinations of 6-pin and 8-pin PCI-E power connectors on every graphics card are supported by NA265A.

High-Performance Computing

Traditional host computer or workstation only has CPU and regular GPU to work with professional applications. However, these conventional data processors cannot even provide a higher processing to meet modern working demands. Hence, by adding the Netstor NA265A GPU enclosure with up to four high-end GPU cards to your host/workstation can let your conventional host computer turn into a supercomputing or high-performance computing workstation.

Computational Finance

GPU acceleration from Netstor NA265A offers financial service organizations the capability to speed up their business processing and provide better analytics. High-end GPUs within NA265A allow complicated risk calculations at the trader level to run in seconds, allowing real-time risk to be business as usual. Value at Risk, Counterparty Risk, and Initial and Lifetime Margining calculations are the types of calculations benefiting from NA265A GPU processing.

Data Science

Increasing number of data scientists are using multiple high-end graphics cards in Netstor GPU enclosure 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, and sorting.

Medical Imaging

Medical imaging takes the advantage of multi-GPU computing to get acceleration. Common use case in medical imaging covers accelerating Advanced MRI Reconstruction and Computed Tomography (CT) Reconstruction. The use of multiple high-end graphics card with Netstor GPU enclosure in this field is matured and there have been many such applications in the medical area.

Numerical Analytics

Professionals can use specialized tools such as MATLAB, Mathematica, and LabViewetc. through the utilization of multi graphics cards in Netstor GPU enclosure for accelerating the numerical analytics computing. Reliable statistics show computing capability of multi-GPU is more than ten times faster than CPU alone.

Outstanding, First-Rate CFM Airflow

NA265A is designed with three front large 9x9 cm cooling fan modules with each fan supporting 51 CFM (153 CFM for all), providing best airflow ventilation to enclosure for most excellent heat dissipation ever, and ensuring graphics cards within chassis running long term without any high temp concern. Moreover, the fan speed of each cooling fan can be adjusted manually according to GPU application situation within NA265A chassis.

Perfect Graphics Cards Compatibility

The Nvidia and AMD GPU cards that are compatible and work greatly with Netstor NA255A enclosure include Nvidia GeForce 10 / 900 series, Quadro P6000 / M6000 series and AMD Radeon RX, R9 series, FirePro W9100 / 9000 series.
