I’m currently testing a compact system that combines routing and storage on a single platform.
The setup includes:
multiple network interfaces (2.5G)
NVMe-based storage
Linux-based system
Current network layout:
WAN → internet
LAN → client devices
separate interface for storage traffic
What I’m trying to understand:
Is using multiple physical NICs actually better than VLAN separation in this type of setup?
Specifically:
does it reduce latency under load?
does it improve stability during large file transfers?
or is VLAN still the better approach?
Also curious about:
how others separate NAS traffic
NVMe performance under mixed workloads
Any insights or real-world experience would be appreciated.
