Synology High Availability Join Synology servers in a centrally managed failover cluster to maximize service uptime and boost the reliability of your business IT — for you and your customers. Synology High AvailabilityCost reductionMitigate the impact of unexpected server malfunctions.Service reliabilityKeep your data and services available and online. The risks of downtime $140,000+average cost per hour caused by IT downtime194%of companies do not survive after suffering catastrophic data loss240%of data loss incidents are caused by hardware failures3 Highly reliable architecture Combine two identical Synology High Availability (SHA)-compatible Synology NAS to create a high-availability cluster. Real-time protection 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. Minute-level failover 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.
For virtualization 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. Simple management Rely on Synology High Availability's unified interface to set up, manage, and monitor your high-availability clusters with ease. Quorum server Help prevent split-brain situations by connecting a quorum node to ensure data consistency.
