Slide Show: Sun To Use Intel Chips In Servers

Sun Microsystems and Intel are the latest archrivals in the IT industry to put down their guns and make peace. The computer giants on Monday unveiled a broad alliance that marries Sun's Solaris Unix OS with Intel's Xeon processors.

Sun has provided a version of Solaris for Intel architecture for more than a decade (and once even pulled the plug on that version when Intel announced its 64-bit processor plans) but has been increasing its support for x32 and x64 systems as Linux appeared on the scene and took a big bite of its market share.

Sun announced a pact with Intel rival Advanced Micro Devices in 2003 and began shipping Opteron systems soon thereafter. Schwartz said Sun's partnership with AMD is intact but added that teaming with Intel is necessary for Sun to reach a broader market.

The deal with Intel also underscores a significant shift in the marketplace, from a focus on OSes and servers to service-oriented architectures and the virtualized data center, Sun and Intel executives said.

Virtualization enables multiple OSes and workloads to run on a single server and be moved from one server to another in a data center, based on a company's on-demand processing needs.

For Intel, the deal with Sun assures that it can support and sell Windows, Linux and Unix on its upcoming multicore processors that offer I/O vitualization and are optimized for OS kernel virtualization.

"The ability to run multiple operating systems on a single microprocessor that began on the mainframe is now coming down to volume servers," Intel CEO Paul Otellini said. Intel currently has four OSes running on a single chip in the labs, he said.

Otellini and Schwartz said they will continue to develop their respective 64-bit Itanium and UltraSparc Unix servers but won't engage in any more "religious wars."

The pact also signifies Sun's effort to regain market momentum by pushing four separate business lines -- systems, software, services and storage -- independent of one another, especially Solaris on industry-standard architectures.

Schwartz said more than 7 million of copies of Solaris have been downloaded since Sun launched its Open Solaris program in 2005, and seven out of 10 of those downloads have been loaded on Intel- or AMD-based systems.

Solaris Unix is far from dead, Schwartz noted. "The issue [of Solaris' survival] is off the table. We clearly have volume, and we can work with Intel to amplify that volume," he said.

Doug Nassaur, president and CEO of True North technology, a Sun partner in Duluth, Ga., said the Sun-Intel alliance should boost the market presence of Solaris.

"It's a better idea [for Sun] to hit the majority of the market than to do something exclusive that misses it. They are in fourth place, so teaming up with the No. 1 [chip maker] can't be bad," Nassaur said. "We use Solaris x86 with great success. Anything that assures commitment to that platform I will view as positive."
