I am thinking about buying a Windows Server 2019 Datacenter license, but I have a few offers to choose from. Namely, this version of the system has many P / N in various sources, e.g. P73-08800, P73-07898, which have information on the emblem that they are Datacenter versions, but I often see the following that only feature the Standard version. I am asking for what product number should I use for me or the other software.
