Hi @Omid_Heravi ,
Current SRM releases are more of 'no.of VMs' based and not CPU which was an option provided in earlier versions.
Note: Always provide product version when raising such queries.
From the screenshot, you have a SRM enterprise license to protect 100 VMs. To check the license usage, please login to vCenter web client --> Licensing --> Solutions --> Assets and look for license usage against your SRM server.
Hope that helps.
