But since this book was first written,
relative price points have continued to collapse making this selection much
easier.
Platform Comparison
The most commonly implemented hardware platform for an Oracle server is the
SMP system, which strikes a nice balance between power and price. SMP systems are
popular for the following reasons:
??? SMP systems offer more and simpler scalability options for the future than uniprocessor
systems.
??? 64-bit processors and operating systems with large memory support enable SMP
systems to handle the needs of very large databases (even containing dozens of
terabytes of data).
Which Platform Deployment Solution? | 303
??? SMP systems have a single operating system and a single Oracle instance to manage
and maintain, unlike clusters.
??? More applications are certified to run on SMP systems than clusters.
??? SMP systems can be less expensive than NUMA, clusters, or grid configurations
in similar CPU configurations because memory and I/O subsystems are not
duplicated to the same degree
This is not to say that other configurations should not be considered.
