Fantastically Fast 25GbE Networking

Twin25G PCIe Card

Dual-port 25 Gigabit Ethernet PCIe Card with Two SFP28 Transceivers

for Mac®, Windows®, or Linux® computers with PCIe card slots

Incredible 25GbE Connectivity

Many bandwidth-intensive workflows — including post-production shared storage workgroups — have reached a point where 10Gb Ethernet does not provide sufficient bandwidth and speed for optimum performance. Upgrading to 25Gb Ethernet is the smart choice — it offers greater performance and works with the same optical network infrastructure as 10GbE. Step up to the Sonnet Twin25G™ PCIe Card, an affordable and powerful solution for adding incredibly-fast fiber optic 25GbE network connectivity.

Make the Switch

Mac users need faster network speeds and increased bandwidth for postproduction workflows. Recently, 25Gb Ethernet switches have become more affordable, but connecting a 2019 Mac Pro® to a 25GbE infrastructure has been expensive. Sonnet's Twin25G PCIe Card is a cost-effective and simple solution for adding 25GbE network connectivity to not only Mac Pro, but also to any computer with PCIe slots.

Efficient NVMe Storage Access

NVMe storage devices are gaining popularity by offering very fast storage access. Sonnet Twin25G offers performance enhancements not only by delivering higher network speed, but also by providing NVMe over Fabric (NVMe-oF) target offloads, enabling very efficient NVMe storage access with no CPU intervention, thus improving performance and reducing latency. Compared to multi-fabric teamed 10G networks, a consolidated 25G storage network achieves significant cost and performance advantages with fewer cables and switch ports, which also lowers power requirements.
