SAN FRANCISCO — EMC Corp.’s (NYSE: EMC) net income more than doubled in the second quarter as corporations opened the spigot on spending for more data storage.

But economic worries because of the European debt crisis and fears of a possible "double-dip" recession in the U.S. have eclipsed encouraging signs from the technology sector. Some investors fear a spike in computer spending may just be a relief valve for pent-up demand that won’t stay open long.

EMC, which has a growing presence in the Research Triangle Park area with both manufacturing and research and design facilities, has now posted three straight quarters of net income increases and said Wednesday before the market opened that it expects to top its earlier guidance for 2010, though it didn’t provide more specifics.

The Massachusetts-based company is the world’s No. 1 maker of data-storage computers and servers.

In the second quarter, EMC earned $426.2 million, or 20 cents per share, up from $205.2 million, or 10 cents per share, in the year-ago quarter. Excluding items, EMC earned 28 cents per share, a penny per share better than analysts expected.

Revenue jumped 24 percent to $4.02 billion, topping the $3.98 billion analysts polled by Thomson Reuters expected.

For all of 2010, the company now says it expects to exceed its previous outlook of net income of $1.18 per share, excluding items, and revenue of $16.5 billion. It didn’t provide more detail.
