(Reuters) - International Business Machines Corp is thinking of selling off its low-end server business and Dell Inc may be among potential bidders, the Wall Street Journal reported, citing sources.

A deal to sell all or part of the world's largest technology service company's x86 server business to China's Lenovo Group Ltd fell through as the two sides couldn't agree on a price, sources had said last year.

Whether Lenovo was still interested in the business and if there are any more potential buyers was not clear, the Wall Street Journal report said. (http://r.reuters.com/bup26v)

The low-margin, but high-growth businesses will help Dell, which has been trying to increase sales, gain scale as it focuses more on enterprise clients.

Founder Michael Dell succeeded in taking the company private in a $25 billion deal last year after prolonged trouble.
