How does Synology High Availability 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.
SHA runs on a wide range of Synology NAS, 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.
Increase the availability of virtual machines stored on Synology NAS and accessed through iSCSI or NFS.
For highly available services
Minimize downtime caused by software updates, hardware upgrades, and system failures on Synology packages and built-in services.
Rely on Synology High Availability’s unified interface to set up, manage, and monitor your high-availability clusters with ease.
Help preventing split-brain situations by connecting a quorum node to ensure data consistency.
