IBM is in "advanced discussions" with Lenovo over a possible deal for it to purchase IBM's x86 server business, according to two reports yesterday.

Any such deal would reshape the massive x86 server market, which was worth $35.8 billion last year and accounted for two-thirds of all server spending, according to figures from IDC.

The sale price isn't known, but the deal could be worth billions of dollars if it goes ahead, according to The Wall Street Journal, which cited unnamed people familiar with the matter.

CRN reported the news earlier in the day, also citing unnamed sources. It said IBM wants $5 billion or $6 billion for the business.

It wasn't clear how advanced the talks are or whether a deal will come about, the WSJ said.

IBM has a history of moving out of lower-margin businesses, the Journal noted. It already sold its PC business to Lenovo, in 2004.

Lenovo, meanwhile, has been trying to expand its share of the server market.
