• High availability for campus core
Aruba Virtual Switching Extension* (VSX) is a high availability technology solution designed using the best features of
existing HA technologies such as Multi-chassis Link Aggregation (MC-LAG) and Virtual Switching Framework (VSF).
Aruba VSX enables a distributed and redundant architecture that is highly available during upgrades inherently by
architecture design. High availability is delivered through redundancy gained by deploying two chassis in the core with
each chassis maintaining its independent control yet staying synchronizing information via the ArubaOS-CX unique
database architecture.
