Sun Microsystems Customers Shape Web 2.0

July 2 2006

Sun Microsystems Inc. (Nasdaq: SUNW - News) today announced new customer adoption of its breakthrough Sun Fire(TM) server family with CoolThreads(TM) technology. DigiTar, Joyent and Fotolog represent a new crop of Web 2.0 customers that have recently moved to the UltraSPARC(R) T1 processor-based Sun Fire server line running the Solaris(TM) 10 Operating System(OS), the most advanced OS on the planet, to both support their growing online operations and to lower power, cooling and space costs significantly in their datacenters.

Web 2.0 Leaders Try, Buy Sun's New Servers

-- DigiTar, a global leader in Web 2.0 and advanced messaging services,

received a Sun Fire T2000 server as part of the Sun Try and Buy

program. After testing the CoolThreads technology with the Solaris 10

OS in their datacenter, the company found better transactional

throughput numbers and much lower energy consumption levels than their

current Intel x86-based servers and made the decision to move away from

their HP servers to Sun's CoolThreads systems. DigiTar is using the new

servers to deliver powerful "in-the-cloud" cyber security services and

unparalleled message processing which cost-effectively offloads

security and message management burdens from clients. Enterprises,

ISPs, SMBs and education clients benefit significantly from DigiTar's

proprietary/High Availability technology, targeted at a rapidly

evolving eMessaging/voice/data security markets. DigiTar assures an

integrated 24x7 turn-key solution for security/management of critical

message Data.

"Scaling open source databases to our exacting levels of performance and reliability is always challenging," said Dale Williams, CEO, Boise, Idaho-based DigiTar, Inc. "Our T2000s have liberated us by reducing 75% of the complexity normally required for our high-availability database clusters. The UltraSPARC T1 has completely overturned the way we plan services and scalability."

-- Taking Web-based team collaboration to a new level, San Francisco Bay

Area-based Joyent also tested the CoolThreads servers as part of the

Sun Try and Buy program. Providing customers software that enables

teams to share emails, calendars, content and shared applications over

the Web, the company needed a way to support growth, scale the business

and save on rising energy costs. The CoolThreads systems demonstrated

superior performance and energy efficiency, prompting Joyent to begin

the move away from their Intel x86 servers from Dell to Sun Fire T1000

and T2000 systems running the Solaris 10 OS.

"Joyent's platform of Ruby on Rails applications (http://www.joyent.com, http://www.strongspace.com ), development tools (http://www.textdrive.com ) and unique collaboration offerings run at a greater throughput and lower operational costs on Sun's CoolThreads servers running OpenSolaris. This allows us to give our community of users and developers access to a great platform at a low price, and offers our Web 2.0 developers a powerful environment where they can scale their applications," said David Young, CTO, Joyent.

-- One of the world's largest photo blogging community, Fotolog looked to

long-time partner Sun to help support a three times explosion inWeb

traffic in less than a year. The Sun sales representative suggested

they evaluate Sun's CoolThreads servers to help alleviate growing

pains. The highly-threaded systems helped get the company back online

and facilitated a four times increase in Web traffic, three times

increase in response time and much less power consumption than their

existing machines. The company has since deployed more Sun Fire T1000

servers to support the millions of users sharing photo blogs on the

Internet.

Sun announced the 'Try and Buy' program last December that let the world experience the benefits of CoolThreads technology free, for 60 days, sparking a new wave of Web 2.0 customers to Sun's server platforms. This wildly successful program has been expanded to include Sun Fire x64 servers running AMD Opteron(TM) processors, workstations and Sun's StorageTek NAS.
