Neverfail for SharePoint is the only "cluster-class" high availability solution to proactively monitor the health of your entire SharePoint environment, including: physical server hardware, network infrastructure and operating system. If any problem occurs, Neverfail can take a variety of preemptive, corrective actions without resorting to a full system failover. In extreme cases, a non-disruptive, seamless failover to your secondary server can occur automatically and transparently to your users.
