NEW YORK (Reuters) – Dell Inc is preparing to sell around $10 billion in non-core assets, including software and services, to reduce the heavy debt load it will be taking on to buy EMC Corp (EMC.N), according to people familiar with the matter.

Dell, which will assume $49.5 billion of debt once the merger with EMC is completed, has communicated the plan to credit rating agencies in recent days, the people said on Monday.

Assets Dell could sell include Quest Software, which helps with information technology (IT) management; SonicWall, an e-mail encryption and data security provider; back-up solutions unit AppAssure; as well as IT services provider Perot Systems, the people said.

The divestitures will not include Dell’s hardware assets such as servers, which are crucial in its quest to dominate the large enterprise market through its merger with EMC, as well as compete more effectively with the likes of Cisco Systems Inc (CSCO.O) and International Business Machines Corp (IBM.N), the people added.

The sources asked not to be identified because the deliberations are confidential. A Dell spokesman declined to comment.

Dell agreed last month to buy data storage company EMC for $67 billion, in a move that would transform the No. 3 computer maker into a leader in storing corporate data and shift its business away from the stagnant consumer personal computer market.
