Ερωτήσεις:

How does the QM8790 compare to traditional Ethernet switches for AI workloads?

The QM8790 offers significantly lower latency and higher bandwidth utilization through its InfiniBand architecture and SHARP technology, making it ideal for AI and machine learning applications that require intensive node-to-node communication.
Can I use existing 100G cables with this 200G network switch?

While the QM8790 uses OSFP56 connectors, it maintains compatibility with appropriate adapters and cables. For optimal performance at 200Gb/s, we recommend using certified 200G cables and transceivers.
What is the typical power consumption of this network switch?

Power consumption varies based on configuration and utilization, but typically ranges between 300-400W under normal operating conditions with all ports active.
