Maximize system uptime with Synology High Availability (SHA)
 
Enjoy a complete hardware and data redundancy solution with Synology High Availability (SHA) in case of unforeseen disasters. After joining two Synology NAS devices to form a high-availability cluster, the NAS acting as the active server will handle all data operations and services, while cloning the entire system to the passive standby server.
 
Automatic failover
 
Real-time protection, minimum data loss
 
No-hassle installation and maintenance
 
Maximize service availability for virtualization through iSCSI
 
 
 
Fully certified storage virtualization solutions
 
Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.
