Features
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.
- SR-IOV
Improves the network performance of virtual machines.
- RDMA (RoCE & iSER)
Reduces latency, lowers CPU utilization, and boosts overall throughput
