It all starts at the data center, Horstmann says. DVDPlay has two of them in California and is getting ready to build a third in the Midwest. Each has about 60 servers, all running virtualization software, housed in just three racks. Each virtual server communicates with multiple kiosks, ensuring optimal utilization, and each is also mirrored to another virtual server, ensuring redundancy and 24x7 operation for DVDPlay kiosks.
Such redundancy is important, especially considering that the servers securely handle sensitive credit card transactions and are expected to register sales within seconds of a customer’s card swipe at the kiosk.
“If you think about 1,200 or more points of retail, with each kiosk communicating directly to the data center, if there’s something wrong with the data center, all of that grinds to a halt very quickly,” Horstmann says. “You need to have a lot of redundancy, and it basically ends up looking a lot like what the banks have done with ATMs.”
Data Center Efficiency and Green grid is what we ought to be looking at today (and the coming years to come)!
