Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions In 2014 and 2013, we leased certain real estate from a company owned by a member of our Board of Directors and such Director’s siblings, for which payments aggregated approximately $3 million and $5 million, respectively. Such lease was initially assumed by us as a result of our acquisition of Data General in 1999 and renewed in 2003 for a ten-year term. The lease expired in 2014 and EMC vacated the facility. In accordance with its written policy and procedures relating to related person transactions, EMC’s Audit Committee approved the transaction. EMC is a large global organization which engages in thousands of purchase, sales and other transactions annually. We enter into purchase and sales transactions with other publicly-traded and privately-held companies, universities, hospitals and not-for-profit organizations with which members of our Board of Directors or executive officers are affiliated. We enter into these arrangements in the ordinary course of our business. From time to time, we make strategic investments in publicly-traded and privately-held companies that develop software, hardware and other technologies or provide services supporting our technologies. We may purchase from or make sales to these organizations. We believe that the terms of each of these arrangements described above were fair and not less favorable to us than could have been obtained from unaffiliated parties.
