Synology SA3400 Virtual Machine Manager s White Paper - Page 6

- Heavy virtual deployments require high-performance Synology setups • Synology products are optimized for storage and writing operations, and less suitable for intensive computing or memory-intensive (e.g. graphical) tasks. • Limited built-in RAM means users who wish to run multiple VM applications on Synology systems will benefit from installing Synology-supported memory extensions and SSD cache. - Hypervisor competes with other applications on mixed-use platform • VMM runs on top of DSM, leading to higher resource use and slower performance compared with bare-metal hypervisors. • If your Synology NAS servers are used intensively for non-virtualization tasks, there might not be sufficient resources for heavy VM applications, and vice versa. • Resources on Synology NAS are not fully abstracted in line with the principles of hyperconvergence and machines need to be migrated between nodes.

Synology Virtual Machine Manager integrates three types of virtualization resources (computing, storage, and networking) on Synology NAS, removing the need to set up a SAN and deal with multiple suppliers. 04
