The built-in High Availability (HA) functionality in Clavister cOS offers you an unprecedented level of security against downtime. Setting up a cluster of Clavister products and configure HA is an easy task. High-end models even have a dedicated HA port for added flexibility. We believe in making things simple and easy to use, so we have included HA in all our products. There is no additional, hidden cost to get HA. With us you have it.
