With grid deployment, youmight continue to leverage older hardware as part
of the existing computing solution.
Second, remember to consider the effect of hardware upgrades, particularly CPU
upgrades, in nongrid solutions. SMP systems and nodes require that all CPUs be
identical within them, so if youu pgrade one youwill have to upgrade all of them. At
some point the vendor will recommend a new system anyway because other internal
features (e.g., memory and I/O bus technologies) will have improved, partly to
match the increased capabilities of the new CPUs.
The grid is tempting to consider since new machine types can be added to the grid as
they become available. Oracle??™s self-tuning and advanced management capabilities
available in Oracle Database 10g and further improved in Oracle Database 11g make
grid computing more practical by eliminating difficult manual tuning efforts that formerly
needed to take into account variations in systems.
