Overview

About the QNAP QXG-100G2SF-BCM

The QXG-100G2SF-BCM 100 GbE network expansion card, supports PCIe 4.0 and provides up to 200Gbps total throughput to overcome performance bottlenecks. Supporting offload functionality including RDMA and SR-IOV, the QXG-100G2SF-BCM greatly boosts network efficiency and is ideal for I/O-intensive and latency-sensitive virtualization and data centers. The QXG-100G2SF-BCM is a perfect match for all-flash storage to realize the highest performance potential for ever-demanding IT challenges.

PCIe 4.0

PCIe Gen 4 x16 provides up to 256 Gbps transfer speeds.

RDMA (RoCE & iSER)

Reduces latency, lowers CPU utilization, and boosts overall throughput

SR-IOV

Improves the network performance of virtual machines.

Compatible with NAS

Supporting the QTS and QuTS hero operating systems, you can easily expand the number of network ports on your NAS for greater connectivity and network bandwidth.

Strengthen your virtualization environment with SR-IOV

The QXG-100G2SF-BCM 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.

Supports RoCE for Reduced Latency and Enhanced Performance for VM Environments

The QXG-100G2SF-BCM 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-BCM 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.

Build a 100 GbE network environment

Increase your IT performance and productivity by using the QXG-100G2SF-BCM with QNAP's 100 GbE switch QSW-M7308R-4X, making it easier than ever to deploy a blazing-fast 100GbE network for your business.
