TECHNOLOGY, DELIVERS A COST-EFFECTIVE PLATFORM FOR
				SECURE WEB SERVICES

SANTA CLARA, CA -- September 10, 2002 -- Answering customers' growing
needs for a more secure and powerful Web services platform at an
affordable price, Sun Microsystems, Inc. (NASDAQ: SUNW) delivers the
Sun Fire[tm] 280R server featuring the 1.015 GHz UltraSPARC III Cu
processor and the scalable and secure Solaris[tm] Operating Environment
(OE). With the more powerful processor, the rack-optimized Sun Fire
280R server offers a performance increase of up to 17 percent over Sun
Fire 280R servers with 900MHz UltraSPARC III processors. In addition,
the Sun Fire 280R system comes bundled, at no extra cost, with the
software required to run Web Services applications helping to enable
customers to reduce implementation time and expense.

Making the Sun Fire 280R server an ideal platform for the delivery of
Web services, the server will come standard with the new Sun[tm] ONE
Application Server 7, Platform Edition and the Sun ONE Studio 4
development tool, Community Edition and Mobile Edition pre-installed
early next quarter. Sun has also pre-installed the Solaris[tm] 8 OE
with Apache Web Server software. Sun has also introduced a special
bundle for secure Web services with the Sun Crypto Accelerator 1000
Secure Socket Layer encryption card.

In addition to the Solaris 8 OE that comes standard on the Sun Fire
280R server, the availability of the Solaris 9 OE for the system adds
enhanced security options for customers seeking a secure Web services
platform.  New security features in Solaris 9 benefit customers by
protecting data through encryption of sensitive sessions, the inclusion
of an enterprise-strength firewall/VPN, improved access control through
single sign-on improvements and the ability to block unauthorized users
from access to the network. The Sun Fire 280R server is one of the
recommended platforms for Sun ONE Network Identity solutions and
iForce[sm] perimeter defense solutions.

"The Sun Fire 280R server provides all the software required right out
of the box for customers to deploy secure Web services with confidence
as well as the performance benefits from the latest UltraSPARC
technology," said Souheil Saliba, vice president of marketing, Volume
Systems Products group of Sun Microsystems. "The Sun Fire 280R server
has been one of the top sellers driving revenues for Sun in the volume
space. From Q1CY02 to Q2CY02, Sun beat Dell, the new HP and IBM by
growing faster than any other vendor in the dual-processor
rack-optimized server market in both units and revenue"*

"We made the switch from Wintel servers to Sun and now all Desert Sky
Software mission-critical applications and databases reside on Sun
platforms," said Luke Holton, president of Desert Sky Software. "Our
Sun Fire 280R servers are used not only as development and database
servers but we also trust these systems for mission-critical
applications. No other server we have found exceeds the reliability of
the Sun Fire 280R."

"Reliability is one of the key pieces to running a successful
production environment. Many of our servers have been running for 365
days without having to be rebooted. That's incredible reliability,"
said, Aaron Clark, Manager of Network Operations for Citadon. "The Sun
Fire 280R servers were the right price point for us. But even more
important than the economics is the superior processing speed we get
from these servers."

Sun Crushes Wintel Competition With Benchmarks to Prove It

A low-cost, high-value, entry-level solution, the enhanced Sun Fire
280R is an enterprise-class, 4U rack-optimized server that delivers
superior performance. In a Webbench 4.1 benchmark measuring dynamic Web
server performance tested by PC Magazine in May 2002, the Sun Fire 280R
outperformed Wintel and Lintel 2-way 2U and 3U servers from the new HP
and IBM by more than 450 percent, demonstrating strong performance for
Web transactions. These superior Web-focused performance results
combined with aggressive pricing helps Sun customers ultimately take
cost savings to their bottom line.
