Right number of cores on T7-1 server

Daniel Morales LetelierOct 6 2017 — edited Oct 6 2017

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)

root@SERVER # psrinfo

root@SERVER # ./showcpucount

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):

                vCPU ids: 0 - 7

        Core 2 (core id: 1):

                vCPU ids: 8 - 15

This server also have LDOM's running:

root@SERVER # ldm list

NAME             STATE      FLAGS   CONS    VCPU  MEMORY   UTIL  NORM  UPTIME

primary          active     -n-cv-  UART    16    31G      0.5%  0.5%  4d 4h 54m

LDOM1            active     -n----  5005    32    32G      4.8%  1.2%  3d 3h 39m

LDOM2            active     -n----  5001    16    96G      1.0%  1.0%  4d 4h 50m

LDOM3            active     -n----  5003    16    32G      0.7%  0.7%  4d 4h 49m

LDOM4            active     -n----  5004    16    96G      3.8%  1.0%  4d 4h 48m

LDOM5            active     -n----  5002    16    32G      0.6%  0.6%  4d 4h 49m

LDOM6            active     -n----  5000    32    64G      0.6%  0.6%  4d 4h 54m

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?
