HP makes its biggest acquisition since 2011's Autonomy buy as it coughs up $2.7 billion for next-generation enterprise mobility and wireless networking solutions provider Aruba Networks.

Aruba holds a 10-13% share of the enterprise WLAN market according to FBN Capital Markets, while HP holds just 4-5%. As such, HP's aim of the buy is no doubt to gain a greater foothold on the market by leveraging on the Aruba brand.

Aruba CEO Dominic Orr and CTO Keerti Melkote will retain leadership of the company, while reporting to HP Enterprise Group leader Antonio Neri.

$2 billion is the price of HP's split into two companies, as divided in $1.3bn in pre-tax separation costs for its current fiscal year (2015), another $500 million for fiscal 2016 and around $750m in foreign taxes.

"The scale of this separation is unprecedented in it's size and complexity," HP CFO Cathie Lesjak explains at the company's fiscal Q1 2015 earnings conference call. Meanwhile CEO Meg Whitman remarks "we are separating into two Fortune 50 companies. It's hard to imagine that there are two Fortune 50 companies embedded inside HP."

The price comes from a lot of one-time costs, including the building of two individual IT systems, consulting fees, legal fees, real estate expenses and, of course, taxes. As a result there will also be an unspecified amount of layoffs.

AMD reveals the "Carrizo" A-series Accelerated Processing Unit (APU) at the International Solid State Circuits Conference (ISSCC)-- a high performance and energy efficient chip designed for notebooks and low-power desktops.

Built as a system-on-a-chip (SoC), the Carrizo combines the latest Bulldozer CPU cores, dubbed "Excavator" (with two modules providing 4 cores) and 8 "Tonga" GPU cores featuring Graphics Core Next architecture v. 1.2. It supports DirectX 12, the AMD Mantle API, H.265 video decoding and, in an AMD first, Heterogeneous System Architecture (HSA) 1.0.

HSA allows the APU to share memory between CPU and GPU for more efficient division of resources between tasks.

Symantec names its recently separate information management business Veritas Technologies Corporation, bringing back the brand name of the storage management vendor it acquired back in 2005.

“Veritas remains a powerful brand that still has tremendous equity with our customers, partners and employees, and after careful review it was an easy choice as the name for our information management business,” Symantec says. “While the name recalls the company’s heritage, the new logo signals that Veritas is ready to solve the most critical information challenges facing our customers today and tomorrow.”

HP Inc., the PC and printer half of the soon-to-split HP, names Herbert Koeck EMEA chief as the company finalises the management teams set to lead its two offspring, HP Inc. and Hewlett-Packard Enterprise.

In other words Switzerland-based Koeck retains his role within the company, since he is already in charge of the HP PC and print business within our territory. He is an HP veteran, having joined the company's Austrian business in the mid-1980s. Since then he has held a number of senior roles within the company.
