Aruba has a market cap of about $2 billion.
The talks with Aruba, which has a market cap of about $2 billion, are not complete and might still fall through, Bloomberg said.
HP and Aruba declined to comment.
HP has had a dismal track record when it comes to major acquisitions. EDS in 2008 and Britain’s Autonomy in 2011 were multibillion-dollar acquisitions that had to be largely written off.
But in recent quarters HP’s management has talked about the need to once more go on the prowl for valuable assets.
The world’s No. 2 PC maker, which has struggled to adapt to the new era of mobile and online computing, is preparing to split into two listed companies this year, separating its computer and printer businesses from its corporate hardware and services operations.
The company reported flat or lower quarterly revenue in all its operating units on Tuesday, and forecast full-year earnings well below analysts’ expectations due to a strong dollar.
Aruba shares jumped as much as 28 percent to $23.49 in evening trading on the Nasdaq. HP’s stock fell 10 percent to $34.63 on the New York Stock Exchange.
