Do You Really Need Failsafe Network TAPs?
Network TAPs are critical tools in network monitoring, providing a passive method to capture and analyze network traffic without disrupting data flow. One feature often highlighted in network TAP specifications is the failsafe or failover feature, which ensures that the Ethernet link remains operational during a power outage. However, in high-availability (HA) network setups, where backup links are typically employed to handle scenarios like power outages, the necessity of this failsafe feature becomes questionable. This article explores the role of network TAP failsafe features, their relevance in HA environments, and why they may not always be essential.
