Securely run Windows®, Linux®, UNIX®, QuTScloud VMs using Virtualization Station Simply plug in a keyboard, mouse, and HDMI™ display to use the VM like a normal PC.
-
VM High Availability
VM Live Migration and HA (High Availability) guarantee continuous operation and minimal downtime.
-
Network & Virtual Switch
Flexibly allocate virtual network resources and configure VLANs to ensure virtual services via the virtual network topology in Network & Virtual Switch.
High availability (HA) and failover with dual-NAS architecture
Avoid unplanned downtime and data loss. Dive into details
Note: High Availability (HA) will be supported starting with QuTS hero h6.
Create a HA cluster with two TVS-h1677AX — one as the active server, and the other as the passive server. If an unexpected failure or issue with the active server occurs, the passive server provides immediate protection with automatic failover. This ensures continuous storage service and system availability.
-
Easy management and monitoring
Use the High Availability Manager app to easily configure, remove, or rebuild clusters.
-
Guaranteed data consistency
Real-time data sync between active and passive servers minimizes the risk of data loss (RPO).
-
Ensured continuity of critical business
The passive server takes over within 1 minute if the active server fails (RTO < 60 secs).
