virtualization was a buzzword just before cloud computing took it to another level.
latest project included mac mini with two extreme fast samsung ssd drives 840. mac mini, server edition, was ordered with 2 500gb drives, quickly replaced with mentioned drives, os x 10.8 mountain lion was installed with vmware 4.0.
one of the virtual machines was web and filemaker server in dmz, connected via usb ethernet adapter to dmz port of shorewall firewall appliance. other virtual machines were using mac mini ethernet port and mapped via static ips to local dns server.
high performance of samsung ssd drives allowed up to 500megabytes per second speeds, which was more than enough for high demand of the web server and both filemaker servers – reboot of host machine and all vms takes less than a minute.
virtualization could save money on hardware, but can also help in managing and administering of the servers. quick reassignment of resources, based on demand, can be accomplished with minimum down time.
