defenses against downtime. For
example, Chipkill™ memory allows
multiple single-bit errors to be cor-
rected using off-the-shelf memory—
helping to protect critical data and to
keep Total Cost of Ownership (TCO)
low.
To further enhance the effectiveness
of Chipkill technology, a Memory
ProteXion™ feature helps contribute
to smooth server operation by
rerouting data in the event of an
on-DIMM chip failure. In addition,
memory mirroring helps minimize
downtime and lost productivity by
writing simultaneously to independent
memory cards.
Hot-swap memory enables the
replacement of failed dual in-line
memory modules (DIMMs) while the
system is still running to maximize
availability for mission-critical applica-
tions. In addition, hot-add memory
supported with Microsoft® Windows®
Server 2003

powers the dynamic
addition of main memory to boost
performance.
Proactive systems management
The x455 comes standard with the
integrated Remote Supervisor
Adapter, a “computer within a com-
puter” that monitors system health
and enables remote management. In
addition, proactive features such as
Predictive Failure Analysis® help
monitor critical system components
and trigger alerts before problems
arise. And, light path diagnostics
helps expedite repairs by pinpointing
problems with components.
Faster data access
For applications with large working
sets of data, the x455 can break
through I/O bottlenecks associated
with 32-bit server platforms, creating
new opportunities for analyzing busi-
ness operations. With data access
latencies falling from milliseconds to
microseconds, further supply chain
optimizations and warehouse inven-
tory analyses become practical even
for smaller companies with aggres-
sive plans for growth. When time-to-
market is paramount, the x455 can
extend server processing capabilities
without requiring the adoption of new
applications or development of IT skill
sets.
