Paul, from the article about PCI-X coming into play and IBM Enterprise X Architecture servers:
The emergence of fast I/O links is helping systems designers drive PC architectures deeper into corporate and Internet data centers. At Comdex, IBM detailed its plans for its Enterprise X Architecture, a set of scalable Intel-based servers that can be configured with as many as 16 processors, 256 Gbytes of RAM and 48 PCI-X I/O slots.
The new IBM systems will come in versions for Intel 32-bit Foster and 64-bit McKinley processors, simply by swapping out a processor interface chip. The servers leverage what IBM describes as mainframe-class capabilities, including hot-swap memory, up to 64 Mbytes of Level-4 cache and a 3.2-Gbyte/s coherent scalability port for linking multiple processors, even across separate chassis.
These are pretty serious specs for 32 bit servers: L4 cache, 256 GB of memory, 48 PCI-X slots. Maybe IBM expects most to sell as, or upgrade to McKinley (Pretty easy upgradability between IA32 and IA64 being made possible by IBM here, at least in the hardware).
