Synology SA3400 Virtual Machine Manager s White Paper - Page 22

Case Studies Der SweITzer, Switzerland Virtualized and non-virtualized solutions on Synology NAS were used together to set up complete digital office infrastructure for a medium-sized service provider. The new setup is highly scalable and combines multiple disparate IT services, yet is easily managed. It also maximizes uptime by combining a VMM High Availability cluster, redundant network configuration, and advanced security features - all on four Synology NAS. Four RS3617xs+ were set up as a cluster. Two were configured both as MailPlus servers and as VMM computing nodes, with RAM expansions to 64GB in addition to SSD cache. The other two were configured as VMM storage nodes and fitted with SSD cache in addition to HDD to speed up storage operations. For the network, a central stack with two switches and a cluster with two firewalls were used. Two of the four LAN ports on each NAS were redundantly connected to each of the two switches using Link Aggregation. The network was separated by VLAN on layer 2 and routing firewall on layer 3 to protect the Synology NAS from unforeseen events. The two VMM computing nodes were set up to operate five VMs, of which four run on Virtual DSM and one on Linux, while simultaneously operating a non-virtualized MailPlus Server cluster.
