Based in Bangalore, Murthy will report to Dell Senior Vice President and CFO Thomas Sweet and Dell Services president Suresh Vaswani, the firm said in a statement today.
Murthy joins Dell from Mphasis, a subsidiary of Hewlett-Packard (HP), where he worked for five years serving as executive vice president and CFO.
Previously, he was finance director for HP GlobalSoft Limited in Bangalore and has also held leading finance positions at Texas Instruments and Thomson Multimedia.
"Ganesh's deep business and finance acumen, impressive track record of financial leadership and strong services background make him a great fit for his new role with Dell Services," Vaswani said.
His appointment will help execute Dell Services' long-term strategy of innovating and driving value for customers and the transformation of business with disciplined cost management, he added.
On his appointment, Murthy said: "Dell has begun a new chapter as a private company. That, along with the tremendous market potential that Dell Services offers, makes this a very exciting opportunity".
Last week, Dell Services had announced that Prasad Thrikutam, who was in charge of strategic sales, marketing and alliances at Infosys, would join the firm as president and global head of its Application Services division from July 28.
In September last year, Dell stockholders approved the proposal in which Michael Dell, Dell's Founder, Chairman and CEO, acquired Dell in partnership with global technology investment firm Silver Lake Partners.
The merger transaction closed on October 29, 2013, and the firm's common shares were subsequently delisted from the NASDAQ stock market.
According to the company's last filing to the exchanges, Dell Services accounted for USD 2.13 billion (over 14 per cent of the company's total revenues of USD 14.5 billion) for the quarter ended August 2, 2013.
