THE COMPAQ CONNECTION TO NEXT-GENERATION
. .
. .
PROCESSING
. .
. .
With its solid leadership in delivering the most flexible computing platforms, Compaq, together
. .
. .
with its strategic partners, is able to provide a smooth transition to next-generation processor
. .
support, unlike other server vendors.
. .
. .
. .
8-Way Technology
. .
. .
Compaq is set to unleash the power of highly scalable processors with 8-way technology.
. .
. .
Compaq will offer 8-processor servers and clustered servers for customers who need the highest
. .
transaction processing power and highest levels of availability. The Compaq ProLiant 7000, a
. .
. .
proven performance leader, is designed to migrate easily to 8-way technology. Combining
. .
Corollary's innovative Profusion architecture and Intel's next-generation Deschutes/Slot-2
. .
. .
processors with Compaq's own systems engineering expertise, Compaq will take 8-way standards-
. .
based servers into the forefront of enterprise technology.
. .
. .
. .
Compaq and Corollary
. .
. .
In the history of standards-based SMP machines, two companies have demonstrated a consistent
. .
. .
vision and commitment to advancing SMP technology: Compaq and Corollary. Compaq and
. .
Corollary announced in early 1997 a technology exchange agreement to develop a standards-
. .
. .
based 8-way multi-processing server. Corollary has designed an advanced memory controller for
. .
its Profusion 8-way architecture. Compaq is bringing its experience with I/O subsystems and PCI
. .
. . Hot Plug technology to enhance this 8-way architecture. Intel was so impressed with this jointly
. .
developed architecture, they recently purchased Corollary.
. .
. .
By entering this technology agreement, Compaq and Corollary are ready to take full advantage of
. .
. .
the Deschutes/Slot-2 processor in SMP servers. The combination of Compaq's I/O design with
. .
Corollary's Profusion system controller and the next-generation Deschutes/Slot-2 processor by
. .
. .
Intel will yield a balanced, high-performance 8-way system architecture for the first time. Intel
. .
has publicly endorsed the Compaq/Corollary architecture as the industry standard 8-way
. .
. .
architecture.
. .
. .
Compaq Implementation of Deschutes Technology
. .
. .
. .
By midyear 1998, Intel will deliver the next-generation Intel 32-bit (IA32) processor, code-named
. .
"Deschutes", offering two processors, Deschutes/Slot-1 and Deschutes/Slot-2. Based on the
. .
. .
current Pentium II processing core, the Deschutes/Slot -1 is targeted for the mainstream server,
. .
mainstream workstation, desktop, and consumer markets while the Deschutes/Slot-2 will be
. .
. . optimized for high-end servers and is the right choice for 8-way systems. The benefits of
. .
Deschutes/Slot-2 systems over the current Pentium Pro and Pentium II Intel processors include
. .
support for a faster Intel 100MHz system bus, large secondary cache size (>512K), and a faster,
. .
. .
full-speed internal cache bus.
. .
. .
The key differences between Deschutes/Slot-1 and Deschutes/Slot-2 processors include:

System Bus Speed:
