How does it work?

SHA combines two Synology NAS servers into one high-availability cluster (or HA cluster). One server assumes the role of active server, while the other becomes a standby passive server. The active server handles all data requests and services, while everything is continuously replicated to the passive server. This provides a complete hardware and data redundancy solution in case of unforeseen accidents. Watch the video to learn more about SHA.

Best-in-class availability

SHA runs on a wide range of Synology NAS servers, so your business can find the best option for your environment and budget. Already chosen by banks, hospitals, universities and governments, SHA does not compromise between cost and reliability.
