Delivers high performance
Incorporating the next generation of
innovative IBM Enterprise
X-Architecture™ technology, the x455
offers competitive performance and
flexible, modular growth options.
From the base 4-way configuration,
administrators can expand the
system by adding processors,
memory and I/O incrementally using
XpandOnDemand™ technology. This
“building block” approach to server
architecture helps reduce the upfront
costs of expensive switch-based
alternatives and delivers investment
protection.
The 64-bit architecture of the x455,
powered by Intel® Itanium® 2
Processors, represents the next step
in the evolution of xSeries servers.
With nearly four times greater
memory addressability than the x445
(224GB versus 64GB), the x455
allows administrators to load entire
databases into main memory for
extremely fast transaction processing
and online queries. This allows the
application environment, such as
enterprise resource planning (ERP)
and customer relationship manage-
ment (CRM) applications to be effi-
ciently utilized, providing a more pro-
ductive operating environment for
these mission-critical applications.
Built on the foundation of EXA, the
x455 establishes a new standard for
competitive performance. With addi-
tional performance enhancements
such as XceL4 system cache, the
x455 can exploit up to 64MB of Level
4 cache per 4-way SMP configura-
tion. This improves latency to main
memory, allowing for more effective
use of the front-side bus for other
resources such as enhancing network
I/O performance.
XpandOnDemand offers growth flexibility
With mainframe-inspired
XpandOnDemand scalability for
processors, memory and I/O, the
x455 can adapt as needs change in
the future. Instead of purchasing
extra capacity in large 8-way or
16-way systems, businesses
deploying the x455 can buy only the
performance capacity and I/O that’s
needed—then use XpandOnDemand
to upgrade the system as their work-
load demands increase. With an
extremely rack-dense 16-way config-
uration, XpandOnDemand makes
scaling up simple.
XpandOnDemand provides a simple
route to high performance using
industry-standard hardware. The
x455 can scale from 4-way to 16-way,
helping businesses respond quickly
to changing requirements. To
increase I/O capacity, the optional
RXE-100 Remote Expansion
Enclosure provides up to 12 addi-
tional Active™ PCI-X slots for triple
the I/O slots without the expense of a
full system upgrade. In addition, hot-
swap and hot-add capabilities for
memory and I/O allow administrators
to upgrade the system without shut-
ting down—helping maintain high
availability and manageability.
Delivering outstanding expandability,
the x455 allows customers to rapidly
add processing power to 64-bit
implementations of existing business-
critical solutions. Processing capacity
can be doubled or even quadrupled
simply by adding new x455 modules
to current systems, avoiding down-
time associated with unnecessary
software reloads. The x455 is the per-
fect choice for IT administrators
seeking a reliable solution when per-
formance levels are variable or
unknown—helping prevent costly
mistakes and helping protect their
investments.
Robust memory, high reliability
The x455 delivers OnForever™ avail-
ability features with a memory sub-
system that provides remarkable
