The Benefits: The project achieved what it set out to do: Allow UST Global to grow substantially--and stay within its datacenter's power constraints. Currently, UST Global operates around 1,000 virtual servers on 20 physical servers, which draw a total of 8 KW. Kurian says that a corollary benefit they were looking to achieve through virtualization was to use storage replication to replicate the company's Trivandrum datacenter in Chennai. Today, in the event of a disaster at its Trivandrum datacenter, UST Global can be up and running from its Chennai datacenter within 60 minutes--from a time when it used to take a day to get everything functional. It also armed UST Global with more efficiency. Thanks to the project, UST Global's customers can request for additional server infrastructure and get it within an hour, from about five weeks earlier. Finally, Kurian didn't have to spend all the $2 million that was allocated to the project; his project cost $1.8 million. More power to him.
