I'm not familiar with server administration and am trying to find the name of a particular service offered by a Japanese website provider. The service is for a dedicated server. I have attached a picture detailing the service below.

The left side of the picture shows the server without the service.

The right side shows the server with the service.

Once I know the name of the service I will Google it, but any additional information in regards to the pros and cons of such a service would be much appreciated. Thanks!


  • What is the name of the service in the picture.
  • What are the pros and cons of this service?

available service for dedicated servers

It looks like some type of load balancing or multi-WAN HA to me. – joeqwerty Nov 9 '12 at 17:07
While the answers provided may be correct, I'm not sure if they are... why don't you link to the service offering and let us take a look to be sure? – HopelessN00b Nov 10 '12 at 3:09
Here it is I feel pretty stupid now, because on reading it again I can clearly see that it says VLAN. – oooooo Nov 10 '12 at 3:16

This looks like it could be describing VLAN:

Looks a bit like OVH's 'virtual rack' service – Guillaume Nov 9 '12 at 18:48

Its some sort of network segregation so that groups of servers are separated and cannot connect to each other.

It could be done using VLANs or by separate physical switches
