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.

Outstanding, First-Rate CFM Airflow

NA265A is designed with three front large 9×9 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.

Can a single host CPU system support more than one NA265A-XGPU-R?

The amount of GPU cards that can be recognized by the system is dependent on the host’s PCIe resources. For Windows, the amount may be around 4 or 5. In a Linux system, it can recognize more GPU cards.

Can I connect a server through a PCIe 3.0 Interface to 4 GTX 1080TI GPUs located in the NA265?

Most the motherboard systems can recognized over 4 GPUs but till have few cases that the PCIe resources design were shortage by the motherboard designer which only can recognize only 3 GPUs so it depends if the PCIe resources are sufficient or not. It means that it’s not related to NA265A.

What PCIe switch is used on the NA2654?

The PCIe switch used on NA265A is Broadcom PEX 8747.

Is the 1350 watt redundant power supply the the sum of both power supplies?

Yes, it is the sum of both. However, if one module malfunctions, the other can support 1350 watts. While both modules are running it will still only support 1350 watts.

At what efficiency do the power supplies run and/or do they meet certain 80 Plus certification levels?

No. The power supply is not 80 Plus certified

What is the Connectivity (specifically PCIe switching) on the NA265A?

The PCIe connection between the computer and the Netstor NA265A is PCIe 3.0 x16 whose bandwidth is 128 Gbps (approximately equals to 12,800 MB/s). The PCIe switch that is used on the backplane within the NA265A enclosure is Broadcom PEX 8747 PCI Express Switch.

What is the Power supply per slot?

There are four downstream PCIe slots in NA265A for the users to install the third-party PCIe/GPU cards. Each downstream PCIe slot itself can provide the standard 75 watts to the third-party PCIe card. Additionally, there are four supplementary PCIe 8-pin power cables and four supplementary PCIe 6-pin power cables from NA265A’s PSU that the user can use to connect them to the GPU/third-party PCIe cards for the supplementary power.

What is the Sound pressure level and acoustic noise (fans)?

Test condition: NA265A’s internal fans running at the default fan speed, while no third-party PCIe/GPU card installed within the NA265A chassis.

When putting the Sound Level Meter in the front of the NA265A chassis with 1 centimeter, the noise level is 17.5 dBA.

When putting the Sound Level Meter in the rear of the NA265A chassis with 1 centimeter, the noise level is 17 dBA.
