Proven reliability and redundancy: The S10, S110, and S330 IPSs are designed to deliver unparalleled high availability. This ensures that network traffic always flows at wire speed even in the event of network or internal device error, or complete power loss. There are two complementary high availability modes of operation—Intrinsic High Availability and Stateful Network Redundancy. And with integrated Zero Power High Availability (ZPHA), a simple power failure does not cause a network outage.
