Hi, I have a T7-1 server that suppose to have 32 cores, according with product information. However, when I check OS information, I get confuse information.
Below you can see OS info, including 'showcpucount' downloaded from https://blogs.oracle.com/mandalika/oracle-solaris:-show-me-the-cpu,-vcpu,-core-counts-and-the-socket-core-vcpu-mapping
root@SERVER # prtdiag | head -1
System Configuration: Oracle Corporation sun4v SPARC T7-1
root@SERVER # psrinfo -pv
The physical processor has 2 cores and 16 virtual processors (0-15)
The core has 8 virtual processors (0-7)
The core has 8 virtual processors (8-15)
SPARC-M7 (chipid 0, clock 4133 MHz)

Total number of physical processors: 1
Number of virtual processors: 16
Total number of cores: 2
Number of cores per physical processor: 2
Number of hardware threads (strands or vCPUs) per core: 8
Processor speed: 4133 MHz (4.13 GHz)
** Socket-Core-vCPU mapping **
Physical Processor 1 (chip id: 0):
Core 1 (core id: 0):

This server also have LDOM's running:

I'm very confused with technical information versus brochure, also about what are the right commands to get CPU info.
My doubt, how to get detailed information about CPU on this server?
