Flexible Resource Allocation in Synology VMM VMM Cluster Virtual machines Synology NAS Ubuntu vDSM Windows vCPU vStorage Figure 3: Users can assign Virtual CPUs and VM storage at will to different Synology NAS in a Synology VMM cluster. In a VMM cluster, computing and storage are integrated on one hardware platform. For each VM, each NAS can be designated a computing or storage node, or can be used to fulfil both roles. When a VMM High Availability cluster detects signs of system malfunction on a Synology NAS, it automatically performs Live Migration of all protected VMs to other hosts. If the original host unexpectedly disconnects or powers down, an identical copy of the VM is started on a passive host to get services running as fast as possible. Synology High Availability allows a complete Synology NAS to failover to another device. However, a passive device must be running at all times and cannot be used independently. VMM High Availability requires a compatible hardware setup that includes at least three Synology NAS systems, yet each device can be used independently for other applications. Fully Back Up and Instant Restore Machines Synology's backup solutions let users maintain full and comprehensive copies of their file systems, ensuring that crucial data is not lost. With VMM, businesses can take their backup plans further by backing up complete virtual servers as they are, including system configuration, and application and system status. VMs reside on top of your Synology NAS' regular operating system, making it possible to create full system snapshots fast. In addition to restoring systems in their entirety, backing up VMs makes it possible to get a backup copy of a system up and running in seconds, reducing your Recovery Time Objective for resuming services. Those who use the Active Backup Suite to create emergency copies of physical and virtual machines or operating systems on other computers can use VMM to run a live copy of their backed-up VMs on their Synology NAS to achieve fast service recovery when other devices crash.
