Replacing high-end Unix with enterprise Linux? Not so fast.

24.11.2008
Migrating from high-end Unix-based systems to commodity x86/Linux platforms has been a popular idea for the last few years, at least in theory. But it turns out that not everyone thinks going full-on with Linux is the best solution -- at least not yet.

, vice president of enterprise operations at , is serious about Linux. He says his company's transition from HP-UX and AIX is ongoing -- and inevitable. "We're migrating and we have a strategy to continue deployment of Linux," he says. "A 100% transition will take place over several years and will be completed as technology is refreshed and as other opportunities arise."

Tony Iams hears that refrain from IT executives frequently. "Companies have had a long-term goal of consolidating all of their Unix systems onto Linux," says Iams, senior analyst with Ideas International, Inc. The most oft-stated goal is to across the board, and that usually means Linux running on x86 hardware.

But Norm Fjeldheim, CIO at Qualcomm Inc., decided to take a pass a Solaris to Linux migration. The company does use Linux for some applications, but Fjeldheim's IT team concluded that migrating its industrial-grade Solaris systems to Linux was a dubious business proposition. "We're not moving from Sun to Linux. We haven't been able to make the economic case for it," he says.

While it appeared at first glance that would save money up front on hardware and operating system costs by migrating, the price comparisons offered by vendors were based on retail prices. "We don't pay retail [and] when we figured our discounts [with Sun], the price advantages went away for Linux pretty fast," he says.

But that wasn't the only issue. His team was not satisfied with the quality of the administrative tools available for the Linux environment. At the time Qualcomm's IT staff did the assessment -- some 18 months ago -- the things that make an administrator's job easier "really didn't exist to the same degree in Linux as they did on Unix-based systems." And that, he says, would have translated into larger administrative costs.
