Hi Jai IT,
for a server with a single processor and 6 cores, you will need to purchase a minimum of 8 core licenses for Windows Server 2022 Standard edition. This is because the minimum licensing requirement for a physical server is 16 cores (2 x 8 core packs). However, you can purchase additional core licenses in increments of 2 if needed.
It's important to note that the number of core licenses required depends on the edition of Windows Server being used and the number of physical processors and cores in the server. You can use the Microsoft Core Licensing Calculator to determine the exact number of core licenses required for your specific server configuration.
Hope it helps.
Kind regards,
Lei
