Explore the Future of GPU Expansion with Netstor NA265A-G4

Netstor Unveils Cutting-Edge HPC-Ready Rackmount PCIe Gen4 GPU Expansion Chassis: NA265A-G4

Taipei, Taiwan – September 12, 2023 – Netstor Technology, a renowned leader in GPU/PCIe expansion products, has just launched the TurboBox Rac NA265A-G4, a 19” rackmount GPU PCIe 4.0 expansion chassis that’s set to redefine data transfer speeds for high-performance computing (HPC) applications.

Blazing-Fast Data Transfers at 256 Gbps

The TurboBox Rac NA265A-G4 is engineered to deliver unprecedented data transfer rates, soaring up to a mind-blowing 256 Gbps between servers and the GPU enclosure. This ultra-high-speed connectivity empowers workflows with unmatched efficiency and responsiveness.

Four PCIe 4.0 x16 Slots for Unleashing GPU Power

Inside the Netstor powerhouse, you’ll find four downstream PCIe 4.0 x16 slots, ready to accommodate up to four triple-width, high-performance graphics cards. This opens up a world of possibilities for server and workstation applications, delivering unparalleled processing capabilities.

Versatile Compatibility with Space Constraints

The NA265A-G4’s host card is designed with a Low-Profile height, ensuring compatibility with both full-height workstations and low-profile 1U/2U PCIe 4.0 and PCIe 5.0 servers. This adaptability means that an existing server can be transformed into a high-performance workstation in a cost-effective manner.

Supercomputing Capabilities for Various Fields

By harnessing the power of the NA265A-G4, servers can be transformed into supercomputing workstations. This transformation offers an exceptional cost-performance ratio, making it an ideal solution for users and administrators in High-Performance Computing (HPC) fields, telecommunications (including cloud computing), and enterprise/corporate applications such as data analysis, surveillance, and storage.

Reliable Power Supply for Demanding Workloads

The TurboBox Rac NA265A-G4 houses a built-in high-efficiency dual-mode 1650W/2000W power supply unit. This PSU provides twelve supplementary 6+2 pin PCIe power cables, ensuring it can meet the power demands of modern GPUs and graphics cards, even for the most demanding heavy workloads and mission-critical applications.

Continuing Innovation in GPU/PCIe Expansion

Netstor’s commitment to innovation shines through with the NA265A-G4. Building on the success of the desktop version GPU chassis, NA255A-G4, which has already found extensive use in video editing, digital content creation, and post-production, Netstor continues to push the envelope in GPU/PCIe expansion. The release of the rackmount-type PCIe expansion chassis NA265A-G4 opens up new possibilities for HPC, telecommunications, and enterprise/corporate applications and solutions.
