How do I find all the Windows Server 2012 R2 servers in the domain and tell which are physical machines and which are virtual machines?
Independent host, that is, Dedicated Server, means that customers rent a server independently to display their website or provide their own services, which has more space and faster speed than virtual hosts, independent CPU computing and other advantages, of course, the price is also more expensive. Today, the editor introduces you to a basic idea to solve this problem:
This is achieved by using a combination of Get-Adcomputer and Get-Wmiobject.
The idea is like this, first see what the property values of a server are available to take advantage of.

See here to know which attribute value to use, filter it, use a wildcard expression or any condition that can hold the value, and then use a select statement to select the name.
$computer = Get-ADComputer-Filter {operatingsystem-like "* 20*"} | select-ExpandProperty name
Then run Get-Wmiobject, and the result is as follows:
[12r2-dc]: PS C:\ > Get-WmiObject-Class win32_computersystem
Domain: abc.com
Manufacturer: Microsoft Corporation
Model: Virtual Machine
Name: 12R2-DC
PrimaryOwnerName: Windows User
TotalPhysicalMemory: 2094039040
Then I thought that if you pass in the variable $computer and expose two more attributes, you will produce a result set, of course, if you are willing to output it to a file and then use pipe characters to output it yourself.
Invoke-Command-ComputerName $computer {Get-WmiObject win32_computersystem}-ErrorAction SilentlyContinue | select name,model | sort model
The result is:
Name Model

12R2-SCCM Virtual Machine
Summary: whether it is an independent host or a virtual host, the requirements of the two functions can be consistent in many aspects, the main differences are: 1, custom software equipment; 2, mass storage and backup; 3, need to set up a lot of websites. Therefore, users should choose whether to use physical machines or virtual machines according to their actual needs. Server rooms are spread all over many countries, and both virtual machines and physical machines have certain reputation and advantages in the industry. can meet the requirements of most users!
