VLAN, or virtual local area network, is a type of network for a group of devices to communicate with each other as if they are in the same domain, regardless of their physical locations. With the flexibility of VLAN, partitioning the network based on your logical segments instead of physical topology not only help improve network performance, but also reduces hardware costs.
VLAN support on Synology DiskStation allows you to relocate your server while still remaining on the original VLAN without hardware reconfiguration. It also helps improve security of your virtualization solution by isolating traffic assigned to different VLANs. Businesses can choose to deploy and partition their VLAN based on corporate strategies or department needs.
