(Reuters) - Dell Inc [DI.UL], the world's third largest personal computer maker, is in talks to buy data storage company EMC Corp EMC.N, a person familiar with the matter said, in what could be one of the biggest technology deals ever.

A deal could be an option for EMC, under pressure from activist investor Elliott Management Corp to spin off majority-owned VMware Inc VMW.N.

The terms being discussed were not known, but if the deal goes through it would top Avago Technologies' AVGO.O $37 billion offer for Broadcom BRCM.O. EMC has a market value of about $50 billion.

Dell is also in talks with banks to finance an all-cash offer for EMC, the person told Reuters on condition of anonymity as the talks were confidential.

Dell spokesman David Flink and EMC spokesman Dave Farmer declined to comment.

A deal could further strengthen Dell's presence among corporate clients at a time when founder Michael Dell has been trying to transform the company he founded in 1984 into a complete provider of enterprise computing services such as Hewlett-Packard Co HPQ.N and IBM IBM.N.

The talks come two years after Michael Dell and private-equity firm Silver Lake took Dell private for $24.9 billion, ending its decades-long run as one of the world’s largest publicly traded PC makers.

ACTIVIST PRESSURE

Elliott, which has been pressuring EMC to spin off VMware, agreed in January to refrain from agitating against EMC for eight months in exchange for two directors backed by Elliott.

Reuters reported last week that Elliott plans to give EMC most of October to respond to its demands after the standstill agreement expired, hoping the extra time would give EMC more room to craft a response to avoid an activist campaign.

“Of all the options potentially on the table, we would view a merger with the now-private Dell as a nightmare scenario that would lack strategic synergies and further complicate EMC’s troubled growth path,” said FBR Capital Markets analyst Daniel Ives.

While a deal would make a “ton of sense” for Dell, EMC/VMware holders would still prefer a breakup of the antiquated federated model and split, he said in a note.

EMC’s so-called “federated business model” comprises its main data-storage unit, enterprise security business RSA, cloud-computing software maker Pivotal and VMware.

In August, Re/code reported that EMC was contemplating a takeover by VMware. The Wall Street Journal reported last year that EMC was exploring options and had held talks with Dell and HP.
