Erez Ofer steps down from the top spot at the storage giant's software unit, as the company increasingly focuses on software efforts.
Erez Ofer, who had been heading the software unit, will hand that role over to Mark Lewis, another executive vice president. Lewis has been EMC's head of new ventures and chief technology officer since joining the storage giant from Hewlett-Packard last year.
"(Ofer) has made great contributions to EMC's technology leadership over the past decade, and has helped us build a strong foundation for our very promising open software business," Tucci said in a statement. "We are fortunate that we have a leader of Mark Lewis' caliber who can step into this important role."
EMC said Ofer is returning to Israel with his family after 10 years at the Hopkinton, Mass., company. Ofer will keep his executive vice president title and report to CEO Joe Tucci in a senior advisor role.
Software has been an area of increased focus for EMC, which has centered its acquisition strategy and much of its research efforts around buying software companies. Most recently the company picked up Astrum Software.
