Introduction In a period of intense competition and emerging technologies, telecommunications

companies face the challenge of delivering and supporting a multitude of new voice and

data solutions. The integration of wireless, video, multimedia, and messaging solutions—

along with skyrocketing growth in user volumes—is forcing the underlying IT

infrastructure to expand rapidly to meet application demands. Although many IT

managers must quickly and dramatically scale datacenter resources to address this

growth trend, they must do so within tight constraints of operating budgets and available

floor space.

For this reason, Oracle’s strategy focuses on engineering innovative processors and

systems with robust compute, memory, and I/O densities to provide higher levels of

throughput—higher by orders of magnitude than existing systems. At the same time,

Oracle’s ecocentric design choices drastically change typical assumptions for required

power and cooling. In pursuit of these goals, Oracle has introduced a second-generation

processor leveraging chip multithreading (CMT)—the UltraSPARC T2 processor with

CoolThreads technology—designed to deliver high throughput within a small power

envelope. The UltraSPARC T2 processor incorporates up to eight cores and 64

processor threads, delivering breakthrough application throughput—up to twice the

throughput of the previous UltraSPARC T1 processor. In addition, the UltraSPARC T2

processor embeds on-chip high-speed networking and improved floating-point

capabilities to accelerate packet processing and multimedia processing workloads.

Oracle’s new Sun Netra T5220 servers combine the certified ruggedness and reliability of

earlier Sun Netra server designs with the performance and ecoefficiency of UltraSPARC

T2 processors. The Sun Netra T5220 systems use a compact 2U-form-factor chassis that

features remarkable expansion capabilities for memory, I/O, and storage. The resulting

ruggedized server offers a dramatic boost in throughput capacity while lowering operating

costs and conserving energy and space—at the same time enhancing availability even

within challenging environmental conditions.
