Getting storage info using PowerShell

I recently encountered a task where I needed to determine the current storage capacity of all servers in a domain. Since there were numerous servers involved, manually logging into each one seemed impractical. To streamline the process, I decided to leverage PowerShell.

I developed a script that retrieves a comprehensive list of servers from Active Directory. Subsequently, the script iterates through each server and retrieves its storage information. The output of the script consists of a well-organized list, presenting the Fixed Drives along with their associated storage details.

Here’s the code:

Import-Module ActiveDirectory
$props = @(
    @{
        Name = 'Server';
        Expression = {$server.Name}
    }
    'DriveLetter'
    'FileSystemLabel'
    'FileSystem'
    'DriveType'
    'HealthStatus'
    'OperationalStatus'
    @{
        Name = 'SizeRemaining'
        Expression = { "{0:N3} Gb" -f ($_.SizeRemaining/ 1Gb) }
    }
    @{
        Name = 'Size'
        Expression = { "{0:N3} Gb" -f ($_.Size / 1Gb) }
    }
    @{
        Name = 'In Use'
        Expression = { "{0:N3} Gb" -f (($_.Size - $_.SizeRemaining) / 1Gb) }
    }
    @{
        Name = '% Free'
        Expression = { "{0:P}" -f ($_.SizeRemaining / $_.Size) }
    }
)

$servers = Get-ADComputer -Filter 'operatingsystem -like "*server*" -and enabled -eq "true"' | Select-Object -Property Name

$output = @()
Clear-Host
Write-Host "##############################################" -ForegroundColor Cyan
Write-Host "###   Getting Server Storage Information   ###" -ForegroundColor Cyan
Write-Host "##############################################" -ForegroundColor Cyan
foreach($server in $servers){
    Write-Host "Checking: $($server.Name)" -NoNewline
    try{
        $result = Invoke-Command -ComputerName $($server.Name) -ScriptBlock {Get-Volume} -ErrorAction 1
        $output += $result | Select-Object $props
        Write-Host " Done" -ForegroundColor Green
    }catch{
        Write-Host " Failed" -ForegroundColor Red
    }
}
$output | Where-Object {$_.DriveType -eq "Fixed"} | ft *
