Western Digital Names Phil Bullinger SVP and General Manager of Data Center Systems Business Unit

San Jose, Ca - April 6, 2017

Western Digital Corp. (NASDAQ: WDC), a world leader in storage technologies and solutions, today announced the appointment of Phil Bullinger to the position of senior vice president and general manager, Data Center Systems (DCS) Business Unit. In his new role, Bullinger will focus on accelerating growth of the company's disk, flash and hybrid storage platforms, as well as object storage systems for use in cloud-scale data centers. He will report to Mike Cordano, president and chief operating officer, and be based in San Jose, California.

Bullinger succeeds Dave Tang who has been named senior vice president of Corporate Marketing, reporting to Cordano. Tang will lead the ongoing transformation of the Western Digital brand, as the company redefines its brand identity and role in the industry from a leading storage device supplier to a thought leader and enabler of data-centric innovation.

Bullinger was most recently senior vice president and general manager at Dell EMC, responsible for the Isilon business, including strategy, product planning, engineering and business operations. Before joining Isilon, he held executive positions at Oracle as their senior vice president of SAN/NAS Storage, and at LSI as the executive vice president and general manager for the Engenio Storage Group.

"Phil brings a 30-year track record of building successful, high growth data center systems businesses," said Cordano. "His substantial management and technical expertise will be extremely valuable as we continue to scale this important growth business by building on the strong foundation Dave Tang and others have helped to establish."

Bullinger's career in storage spans a number of engineering and management roles from silicon to system-level products that have defined and led their respective market segments. He holds five patents in the fields of storage technology and integrated circuit design. Bullinger earned a Bachelor of Science degree, magna cum laude, in Electrical and Computer Engineering from Kansas State University, and a Master of Science degree, magna cum laude, in Management of Technology from the National Technological University.
