Synology SA3400 Virtual Machine Manager s White Paper - Page 11

Configuration Guide Creating virtualized environments requires detailed hardware planning, whether you intend to set up essential IT infrastructure or a small number of experimental instances. Some virtualization scenarios may require specific add-on components or configurations. This section guides you through the essential considerations and requirements for different uses of Synology VMM. It also explains how the different elements of a VMM cluster interact. Please beware that neither minimum requirements nor recommended setups are guaranteed to support your specific use case. We therefore strongly recommend that you test the viability of your plans using VMM's many free features and our free 30-day VMM Pro trial, available for each compatible Synology NAS. Essential Checks Before You Start Before you proceed with your virtualization plans, please check whether your hardware meets the minimum requirements for execution. The most up-to-date list of compatible Synology NAS can always be found on the VMM package page. This tells you whether your device can run VMM. Compatible file system In addition to the right model number, your prospective host server should have at least one volume configured with the Btrfs file system. VMM does not run on any other file system. Btrfs enables many of the advanced data protection and space reclamation functions for VMs on Synology NAS. Number of virtual machines If your Synology system is capable of running VMM, it is now time to check whether your planned applications can be successfully virtualized. Recommended VM instances per host range between 2 and 32 machines for different Synology NAS models. Exact numbers of recommended guests per host can be found in Support Center. These numbers are based on VMs with 1 virtual CPU (vCPU) and 1GB of RAM each. Many typical applications will require more resources. (Minimum recommended memory for many operating systems is 2GB). This article provides model calculations to estimate the true number of VMs that can run on your system. Please note that these are based on the parameters you set for each VM. To arrive at a realistic estimation of VM requirements, it is best to test actual virtual resource use of your application in VMM using the actual operating system to be used. 09 Configuration Guide
