QNAP Unveils the QXG-100G2SF-BCM Network Card
QNAP has announced the QXG-100G2SF-BCM network card, designed for users who require extremely high data transfer speeds. The PCIe expansion card is equipped with two QSFP28 slots, each providing up to 100 Gbps bandwidth.

The device is powered by the Broadcom 57508 chip. It is designed for a PCIe 4.0 x16 slot to achieve maximum speed but is also compatible with PCIe 3.0, albeit with reduced performance. An active cooling system ensures stable performance under load. The integration of Remote Direct Memory Access technology allows data transfer directly to memory, bypassing the CPU, thereby reducing CPU load and latency.
Compatibility Across Platforms
This card is compatible not only with QNAP’s professional NAS systems (operating on QTS and QuTS hero) but also with standard PCs running Windows 11 and Windows Server. Various mounting options are included in the package. The cost is $1000.
Advanced Features and Industry Reception
Recent developments in PCIe technology have enabled these kinds of speeds, which are essential for high-performance computing and data centers. The QXG-100G2SF-BCM stands out with its support for dual 100 Gbps connections, a feature only paralleled by a few competitors.
RDMA support on the card offers marked improvements for applications requiring low-latency and high-throughput data transfer. Industry experts highlight the potential impact in sectors such as finance and scientific computing, where every microsecond counts.
Growing Demand and Market Trends
The demand for higher speeds and reduced latency in data transfer continues to rise, with market trends showing an increased investment in network infrastructure capable of supporting next-generation technologies.
