Dell has posted second-quarter revenue of $11.7 billion, 20 per cent higher than the same quarter a year ago.

The company reported net income for the second quarter of $799 million, or 31 cents per share. That figure compares with $621 million, or 24 cents per share, reported in the same quarter a year ago.

According to a statement, sales in Europe, the Middle East and Africa, and in Asia-Pacific and Japan rose 30 per cent and 29 per cent, respectively.

Combined revenue for enterprise systems, including servers and storage systems, accounted for 22 per cent of overall sales, matching a company high.

The company said that a 31 per cent second-quarter increase in server shipments was above the average server growth for other companies, and it said revenue from software and peripheral products rose 31 per cent, aided by strong demand for Dell printers.

Dell CEO Kevin Rollins said: "Third-quarter shipments are expected to be 21 per cent higher than in the same quarter last year. That growth is expected to produce quarterly revenue of about $12.5 billion, up 18 per cent, and earnings per share of 33 cents, a 27 per cent increase from the third quarter of the previous fiscal year.

"Like our shareholders, our expectation is for volume and share growth along with solid profitability. Those objectives aren't mutually exclusive."
