New 25GbE QNAP NIC

QNAP® Systems, Inc. today unveiled the new dual-port 25GbE QXG-25G2SF-CX4 and 10GbE QXG-10G2SF-CX4 network NICs. Featuring Mellanox® ConnectX®-4 Lx SmartNIC controllers, these cards can greatly boost file transfer speeds and also support iSER (iSCSI Extension for RDMA) to optimize VMware virtualization. Both cards are PCIe Gen3 ×8 and can be installed in a Windows®/Linux® PC or compatible QNAP NAS. 

“Cloud, big data, high-speed storage, virtualization, and AI are strongly pushing 25GbE into the mainstream,” said Dan Lin, Product Manager of QNAP, adding “QNAP now provides users with a scalable solution for adopting 25GbE infrastructure by leveraging the industry-leading Mellanox Ethernet solution to deliver a next-gen 25GbE NIC for NAS, servers and workstations."

The QXG-25G2SF-CX4 and QXG-10G2SF-CX4 provide flexible 25GbE and 10GbE connectivity and iSER support to meet today's high-speed requirements. When used with high-performance NAS (such as the TS-x83XUTVS-x72XU, or TS-x77XU) users can benefit from lightning-fast throughput for massive data transmission, fast backup/restoration, maximized SSD-based applications, and optimal VMware performance.

The QXG-25G2SF-CX4 and QXG-10G2SF-CX4 can work with server-grade PCs to speed up workflows in offices and homes. Users can download Windows and Linux drivers from Mellanox. QTS 4.3.6 (or later) is required to use the QXG-25G2SF-CX4/ QXG-10G2SF-CX4 with a QNAP NAS.
