1.12 Enterprise X-Architecture
IBM's Enterprise X-Architecture technologies yield revolutionary advances in the
I/O, memory, and performance of xSeries servers. This design creates a flexible
"pay as you grow" approach to buying high-end 32-bit and 64-bit xSeries systems
that can be scaled quickly, easily, and inexpensively. Enterprise X-Architecture
technology is designed to achieve unparalleled levels of availability, scalability,
and performance in industry-standard enterprise computing.
Enterprise X-Architecture technology enables the following capabilities:
XpandOnDemand scalability
System partitioning
PCI-X I/O subsystem
Active PCI-X
Remote I/O
Active memory
High-speed (DDR) memory
Memory ProteXion
Chipkill memory
Memory mirroring
Hot-add/hot-swap memory
XceL4 server accelerator cache
These features deliver application flexibility and new tools for managing
e-business. They bring to industry-standard servers the kinds of capabilities
formerly available only to users of mainframes and other high-end systems.
Combined with existing X-Architecture technologies, these innovations result in
