Enable enough CPU for your servers and multiplexing services. In addition, enable enough CPU for any RAID systems that you plan to use. If you intend to use archiving in your deployment, you need to take those space requirements into consideration as well.
Use Table 20–2 to help determine the number of CPUs your installation requires for optimum performance whether archive is enabled or disabled. The figures listed in the table were generated using a 400MHz Ultra SPARC II Processor.
