QXG-100G2SF-CX6

2-port ultra-high-speed 100GbE networking with low latency

Compatible with NAS and PC

QNAP Network Expansion Cards support NAS operating systems (QTS and QuTS hero), Windows® 10, Windows Server® and Linux®, allowing you to expand the performance potential of all your networked devices.

Pair with high-speed switches for high-performance, low-latency data transfer

The QXG-100G2SF-CX6 network expansion card can be connected to a switch with QSFP28 cables or transceiver, for an incredible total throughput of up to 200GbE.

• 100GbE to 100GbE with more NAS

  Connect two or more NAS systems installed with the QXG-100G2SF-CX6 to a 100GbE switch to form a high-speed storage environment.

• Up to 200GbE total bandwidth

  Connect two 100GbE ports on the QXG-100G2SF-CX6 to a 100GbE or faster switch for obtaining 200GbE maximum total bandwidth.

Unleash the full potential of the NVMe all-flash NAS

Install the QXG-100G2SF-CX6 in an NVMe all-flash NAS (TS-h2490FU, TDS-h2489FU, and TS-h1290FX) that features PCIe Gen 4 x16 slot(s) to fully realize 100Gbps performance and eliminate bottlenecks in modern data centers, virtualization, cloud applications, and mission-critical backup/restore tasks.

Strengthen your virtualization environment with SR-IOV

The QXG-100G2SF-CX6 supports SR-IOV, which can allocate bandwidth resources from a physical network card directly to VMs on the NAS. It helps improve network efficiency, ensuring reliable VM applications and reduced CPU overheads.

Note: SR-IOV is supported by specific QNAP NAS models and should work with SR-IOV compatible adapters. Click here to check supported NAS models.

Supports RoCE for Reduced Latency and Enhanced Performance for VM Environments

The QXG-100G2SF-CX6 supports RoCE, which can access a network directly in RAM to effectively reduce latency and enhance performance and efficiency for VMware® virtualization environments.

Supports iSER for Improved VM Performance

The QXG-100G2SF-CX6 supports iSER, combining iSCSI and RDMA (Remote Direct Memory Access), which can bypass general network drivers, the socket layer, and to directly enter memory buffers of the server and storage. Response time is also reduced to ensure service quality of the NAS.

Ensure reliable data transfer with Forward Error Correction (FEC)

The QXG-100G2SF-CX6 supports FEC to overcome packet loss – a potentially common occurrence in fast, long-distance networks. FEC helps the receiving side detect and recover lost data to correct bit errors, thus ensuring reliable data transmission over “noisy” communication channels. With three FEC modes, you can use a suitable cable and switch to build an optimal network environment.

Mode	Latency	Distance
NO FEC	Lowest	Shortest
BASE-R FEC (Firecode)	~ 80ns	Middle
RS-FEC (Reed Solomon)	~ 260ns	Longest

1. The transmitter (source) and the destination (receiver) must use the same mode.
2. If the QXG-100G2SF-CX6 cannot connect to the switch, please check if the latest firmware of the switch supports FEC. If FEC is not supported by the switch, the FEC function of the NIC should be disabled using the NAS or computer operating system.

Supports Windows and Linux servers/workstations

Besides QNAP devices, the QXG-100G2SF-CX6 supports many platforms (including Windows Server® 2016 and 2019, and Linux®/Ubuntu®) allowing you to attain optimal business performance for a wider range of system applications and services. The higher bandwidth density with reduction in links helps reduce cabling footprint and operational costs.

• 

  Faster Server

  Faster server connections within data centers accelerate data aggregation and operational performance.

• 

  Denser Compute

  Boost the productivity of compute-demanding tasks such as cloud computing, virtual machines, containers, and more.

• 

  Bigger Data

  Empower the movement of large files from surveillance streams, 4K/8K media, Internet of Things, and more.

Note:
1. Always consult the compatibility list before purchasing add-ons and accessories for your NAS.
2. QNAP Network Expansion Cards do not support Wake-On-LAN (WOL).
