Feature
Synology High Availability ensures seamless transitioning between clustered servers in unexpected disasters and ensures that your services remain online. Snapshot Replication provides schedulable, near-instantaneous data protection, ensuring that your business documents in shared folders, virtual machines in iSCSI LUNs, or dockerized application data remain safe and available in a disaster. Redundant power supplies (RS820RP+ only), system fans and network ports with failover support ensure continual service uptime. High reliability system design, including fan-less CPU heat sink and passive cooling technology, prevents single points of failure.
