Intel Data Center Group (DCG) General Manager Diane Bryant is taking a six to eight-month leave of absence for family reasons, and will be replaced by Navin Shenoy, the company announced Wednesday.

Shenoy will take over the DCG, Intel's second highest-revenue unit, after having been general manager of Intel's Client Computing Group (CCG), the company's unit by revenue. Bryant had led the group since 2012, before which she was Intel's CIO.

In an email to employees, Intel CEO Brian Krzanich announced the change, saying the time frame made the appointment of an interim replacement impossible.

"Diane has transformed DCG from a server-centric group to a business that spans servers, network, and storage across all end-user segments, and with product lines and business models that extend beyond the traditional,” Krzanich wrote. “DCG’s leading products and strategies — driving industry transformations' to pervasive cloud computing, virtualization of network infrastructure, and adoption of artificial intelligence solutions — have positioned the business to be the growth driver for Intel."

DCG revenue rose 6 percent (year over year) to roughly $4.2 billion in the latest quarter, making up over 25 percent of the company's total revenue.

Also on Wednesday, Intel Autonomous Driving Group SVP and GM Doug Davis wrote in a blog post that he has delayed his retirement to remain in his executive position with the company due to the excitement of the unit's progress and potential towards self-driving cars. Davis cites IDC research showing that the 1.8 zettabytes of data generated in 2011 will grow to over 40 zettabytes by 2020, along with Intel's track record in navigating industry change as indications of Intel's role in big data transformation.

Google upgraded its cloud data center servers with the latest Intel Xeon processors earlier this year, saying is was the first cloud provider to do so.
