As a subsidiary of its hardware maker, Dell's software business will feature four major areas: cloud computing, security, data analytics and mobile Internet. Tom Kendra, vice-president and general manager at Dell Software, said these areas will cover most of the key aspects for enterprise-level software business and give Dell sufficient strength to compete with other software providers.

Dell said its software products' mobility features will help them to attract new customers because an increasing number of companies want mobile office programs to raise efficiency.

The company is offering an "end-to-end solution" to help its customers take advantage of new technologies such as the consumerization of IT, cloud computing, data insights, security and business intelligence.

The company is also underscoring its software reseller network. The company has launched a support platform allowing its channel partners to sell Dell-branded software products in a uniformed structure.

"Software is the catalyst to modernizing today's IT environments, enabling organizations to do more and achieve greater business results," said Swainson.

Global PC makers are vigorously looking for new profit boosters as lackluster world PC demand is pushing them into a corner.

Global PC shipments are likely to witness a double-digit slump in the second quarter of this year as demand in China, which accounted for more than one-fifth of global demand, shrank faster than expected, industry research company IDC warned in April.

Some PC makers have already begun readying themselves for the impact as the first evidence of the shift showed up about five years ago.

Lenovo Group Ltd, China's top PC maker and the world's second largest, is eyeing enterprise-level business to spur profit margins although the Beijing-based company was able to outpace the market in the last quarters.

"We are looking for sectors that could help generate profit in the post-PC era," said Chen Xudong, senior vice-president and general manager of Lenovo's China unit. "Enterprise-level server and storage markets will surely fill this need."

'Not science'

Dell's longtime rival HP started to enter the software market in mid-2005. Its software business revenue grew 14 percent year-on-year in the fourth quarter of last year with an operating margin of more than 27 percent, according to the company.

Swainson estimated a reasonable scale for Dell's software group is somewhere around $5 billion, but he refused to predict when the company could hit the target.

"It's not science, but there is some benchmark if you look at the software business of HP," said Swainson.

Industry insiders said Dell's ailing PC business made the growth of the software unit more urgent.
