Frequently Asked Questions
How large a fabric can a 9332D-GX2B spine support?
With 32 400G ports and breakout to 128x100G, a single switch can interconnect a large number of leaf nodes in a non-blocking spine-leaf pod.
What does CloudSec add over MACsec?
CloudSec extends line-rate encryption across multi-site VXLAN fabrics, securing traffic between data centers, while MACsec protects point-to-point links.
Is it suited for AI fabric backbones?
Yes. Its 12.8 Tbps non-blocking capacity and low-latency 400G ports make it a strong spine for GPU cluster and IP storage fabrics.
