94%

of companies do not survive after suffering catastrophic data loss

40%

of data loss incidents are caused by hardware failures

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.
