Appendix A System Configuration A-7
A maximum of 16 CMUs (64 CPU chips / 128 cores) and 16 IOUs can be mounted in
this model. A total of 128 core expansion is possible. The primary units such as the
CMU, IOU, power supply unit, and FAN unit are common among the SPARC
Enterprise servers. This is a floor-stand type. (128 cores for the SPARC64 VI
processors, 256 cores for the SPARC64 VII processors)
