Tech Startup Tackles Energy Use by Data Centers

Data centers in the U.S. have created a carbon footprint that is larger than that of countries such as The Netherlands and Argentina. Internet companies such as Google are investing billions of dollars in setting up massive data centers and struggling to control soaring power usage. While Google may want its users to trawl thousands of terabytes of data and get their search results almost immediately, this activity gobbles up plenty of energy.

Here’s the problem for companies such as Google: power usage by data centers accounts for around 2 percent of all the power supplied to the U.S. grid and 2-3 percent globally.

As companies struggle to balance their quest for greater computing capacity while controlling power use, they are turning to technology for answers. Virident, a California-based startup set up by a couple of IIT grads who also went to the same graduate school at University of Illinois, is looking to address this issue using by enhancing the memory capacity of servers using specially designed flash memory chips (commonly used in cell phones, for example) to increase the computing capability of servers.

Virident (derived from Viridus in Latin meaning green and dent meaning to make; literally to make green), was started by Kumar Ganapathy and Vijay Karamcheti, who blended their experience across the semiconductor industry and academia to set up this company.

Ganapathy was a Fellow with Rockwell Semiconductor before he set up his own start-up, VX Tel, which built voice over IP chipsets, and then worked with Artiman Ventures. Karamcheti worked with Google and spent the last 15 years working on parallelization techniques at New York University.

The duo has teamed up with an assortment of business acquaintances to set up Virident and embed these flash memory chips in data centers. As a first step, the company roped in Raj Parekh, a…
