RDMA (RoCE & iSER)
Reduces latency, lowers CPU utilization, and boosts overall throughput.
High Availability (HA) Support
Enables cross-switch failover and redundancy for uninterrupted business continuity.
Link Aggregation
Combines multiple ports for higher bandwidth, load balancing, and network resiliency.
100Gbps High-Availability Networking for Enterprises
Use the QXG-25G4SF-BCM with QNAP’s 10GbE switches to build budget-friendly high-speed network environments.
- Uninterrupted Uptime – Multi-port redundancy and link aggregation keep your services running, even if one connection goes down.
- Seamless Failover – Low-latency performance ensures rapid node switching, minimizing disruption during HA events.
- Reliable Data Flow – Advanced acceleration and error-handling features safeguard performance, keeping business-critical workloads smooth and stable.
Strengthen your virtualization environment with SR-IOV
The QXG-25G4SF-BCM supports SR-IOV, which can allocate bandwidth resources from a physical network card directly to VMs on the NAS. It ensures 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.
