Performance Desktop PCIe 3.0 x16 (128Gbps) upstream port PCI-Express expansion enclosure particularly design for GPU cards (Available up to 4* double width PCIe Gen3 slots)

128Gbps Bandwidth – PCIe Gen3 x16
The Netstor NA255A 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 NA255A 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.

1 Netstor is dedicated to providing high C/P value GPU enclosure solution. According to graphics experts' test, there will be only 1% GPU performance difference when GPU card is installed in between PCIe x8 and x16 electrical. Please refer to AnandTech and TechPowerUp.

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 NA255A 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.
