Metro VCS overview
Metro VCS allows you to interconnect different locations and form clusters of data centers over long
distance in order to provide disaster protection/recovery and load sharing.
There are multiple ways to stretch an Ethernet fabric over distance. By using Inter-Switch Links (ISLs)
over long distances (more than the standard 1000 m), Ethernet fabrics can be distributed across data
centers located in geographically different locations.
If more complex setups are needed within different locations, then local VCS fabrics can be used, as
shown below.
