Google Said to Be Testing Sun's Open-source Solaris

Technology may be alternative to Linux in server network, sources say

September 25, 2006 12:00 PM ET

Computerworld - Google Inc. is experimenting with the open-source version of Sun Microsystems Inc.’s Solaris operating system as apossible prelude to running it alongside Linux in its massive global network of servers, according to sources.

With dozens of data centers housing hundreds of thousands of Intel servers supporting its flagship search engine, a move by Google toward Solaris would be a vote of confidence for Sun’s operating system.

Google officials last week declined to comment on the company’s OpenSolaris plans.

Sun CIO Robert Worrall said that Google is one of several large companies using open-source implementations of Solaris, including Solaris 10 and Solaris Express.

“Google, eBay, Yahoo — pick your favorite,” said Worrall, whose internal IT team runs Solaris Express, the executable version of the OpenSolaris source code, on systems throughout Sun and has advised many customers on its deployment.

Worrall said that Google runs a “significant amount” of Solaris in its data centers and is one of a number of customers “excited about the possibility” of installing more Sun servers based on Advanced Micro Devices Inc.’s Opteron processors and running some version of open-source Solaris.

Sources, including Sun, said that the list of Solaris 10 users also includes eBay Inc., which touts its use of the open-source operating system on its Web site, Yahoo Inc., Vonage Holdings Corp., Wal-Mart.com USA LLC, Disney Mobile, Reuters Group PLC and Bear, Stearns & Co.

Sources outside Google of saidthat its servers currently run a stripped-down version of Red Hat Linux that has been modified by the company’s engineers. A Solaris systems administrator who recently interviewed for a job atGoogle said that he was told by employees there that the search engine vendor plans to create and test its own modified version of OpenSolaris.

Stephen Arnold, a technology consultant and author of The Google Legacy, said that he is “100% certain that there are literally dozens of people horsing around with Open­Solaris inside Google.”

Switching to OpenSolaris would be a natural move for Google, which has a large number of former Sun employees and is striving to push the performance of its data centers, Arnold said. But he added that he doubts Google is widely deploying OpenSolaris yet. “Will it quickly replace Linux anytime soon? No,” he said.

The growth of Solaris since its unveiling as an open-source offering some 15 months ago is seen by some as a sign of resurgence for the nearly 20-year-old operating system.

According to Sun, more than 5 million users have registered to use Solaris 10 since its release in January 2005, a figure that includes those paying Sun for support and those using it for free. And market researcher IDC said that Sun’s share of the server market rose to 12.9% in the second quarter of this year, up from 11.2% a year earlier.

Enterprise Data Center Network Reference Architecture
Simply designing a data center that only deploys more servers, storage and devices significantly increases network complexity and cost. The data center network also must offer components such as security, performance acceleration, high density and a resilient network infrastructure. This document shares Juniper Networks best practices in designing a highly efficient, secure, scalable and flexible data center network.

Advancing the Economics of Networking
Aging network systems and old habits have dictated how businesses spend their IT budgets. As a result, a large percentage of IT dollars are being spent to “stay in the race.” While this model keeps revenue streams flowing for legacy network vendors, it doesn’t necessarily help businesses gain a competitive advantage. Juniper is changing this economic model by delivering a new family of solutions that reduce capital and operational expenses. By freeing up IT budget dollars, Juniper allows businesses to invest in other innovative technologies that will further reduce the cost of doing business while improving their competitive position.
