If they require 3/4 to a full\maximum configuration of a largersystem, they are likely
to have increases in capacity requirements. Thus I think IBM is tryingto push those with
such higher capacity requirements, to move directly into the 570 dueto its modular design,
failover & redundancy, CUOD, and capacity to grow. While a typical OSfor p&x may tend
horizontal, i tends vertical. The 550 will presumably never grow above8 cores, and it
would seem to me only natural, that the 550 will become an effectivesubset of the
modular 570 design. Starting with an 8-core 550 will require ahardware change to a
570 for any topped-out configurations. Discouraging suchconfigurations up front,
limits the number that would have to change to achieve verticalgrowth. Some may
argue that the customer knows better, or is always right, but I thinkanyone can
point to many counter examples. After continually consolidating moreand more
workloads, having chopped off much of their past horizontal growth,plus typical
growth within any of those workloads, I am aware of several largesystems that
/required/ growing larger to the point of needing even more than themaximum
supported number of CPU.
