5 High Availability for Network Services

For systems that provide network services to clients inside the network, network availability becomes a priority to ensure that the services are continuous and interruptions are prevented. With virtual local area networks (VLANs), you can also organize the network such that systems with similar functions are grouped together as though they belong to their own virtual networks. This feature improves network management and administration.

For a system to avail of these advanced features, it must have several NICs. The more NICs, the better assurances of network availability that a server can provide.
