Customer testimonials "If we lost our data, I'd be . The goal of a high availability cluster is to make sure that critical resources reach the maximum possible availability. High availability is not only important for customer-facing software but if the monitoring infrastructure is not highly available, then there is a risk that operations people are not notified of alerts. The Market of High Availability Software is growing due to the factors like demand for high availability and real-time data access, there is a growing use of virtualization to reduce operational costs, and also the demand from enterprises to reduce downtime is increasing as the data across enterprises . Accomplishing corporate sustainability is a big priority for global corporations. The widely-held but almost impossible to achieve standard of availability for a product or system is referred to as 'five 9s' (99.999 percent) availability. HA generally ensures that if a server node or a path to the storage system goes down (expected or unexpected), nearly 100 percent of all the data requests can still be addressed and served. A step above, 99.99%, or "four nines," as is considered excellent uptime. Harmonic is using SafeKit as a software OEM high availability solution and deploys it with its TV broadcasting solutions over satellites, terrestrials, cable, IPTV..
