Introduction
In May 2002, Apple introduced Xserve, a high-density, 1U rackmount server that was
applauded for its value and versatility. In 2003, we built on that success with perfor-
mance enhancements, more storage, and flexible build-to-order options. In January
2004, we gave this highly acclaimed server a huge burst of power by introducing the
64-bit PowerPC G5 processor—accelerating a wide range of intensive server chores
and High Performance Computing (HPC) applications. Now we are pushing perfor-
mance even further, increasing the speed and capacity of the Xserve G5 to meet
customers’ ever growing need for processing power.
With the debut of the PowerPC G5 in Apple‘s Power Mac G5, users were able to tackle
projects never before possible on a desktop system. In fact, its performance was so
remarkable that Virginia Tech chose the G5 processor as the engine for its supercom-
puting facility. Virginia Tech achieved such groundbreaking results that they quickly
upgraded their 1100 systems to 2.3GHz Xserve G5 systems, attaining 12.25 teraflops
and pioneering the way for the introduction of the 2.3GHz processor now available
in the Xserve G5. Combining the superefficient PowerPC G5 with high-bandwidth,
server-optimized system I/O and fast internal storage, Xserve G5 delivers outstanding
computational performance in a 1U enclosure.
In addition to robust hardware features, Xserve G5 comes complete with an unlimited-
client license for Mac OS X Server software, a host of powerful network services, and
integrated remote management and monitoring tools. Easy to set up and easy
to maintain, Xserve G5 with Mac OS X Server dramatically reduces the complexity
of system administration and minimizes maintenance costs. For added peace of mind,
Apple offers enterprise-class service and support products for Xserve G5 hardware
and Mac OS X Server software, with a single vendor to call.
This uniquely Apple integration results in superior performance, unparalleled manage-
ability, and increased uptime—enabling organizations to lower their total cost of
ownership and reduce the pressure on network administrators. Whether in small or
large businesses, higher education or K–12 schools, creative departments, or science
and technology research centers, the affordable Xserve G5 is perfect for today’s new
breed of UNIX-based server solutions.
