Highly reliable architecture
Combine two identical Synology High Availability (SHA)-compatible Synology NAS to create a high-availability cluster.
Achieve a near-instant Recovery Point Objective (RPO) by replicating data in real time between an active server, which handles all requests, and a passive server, which remains on standby.
Bring your business back online with a minimal Recovery Time Objective (RTO) by automatically failing over all data and services to the passive server should the active server be unavailable.
Keep critical workloads running
Ensure the continued operation of virtualization environments, setups running large numbers of concurrent applications, and resource-intensive deployments supporting critical services.
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.
Set up for stability
Intuitive features help you further enhance the efficacy of your high-availability clusters.
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.
