vSAN Storage Policy Summary using PowerCLI
I recently came across a need to review the Storage Policies in use within a vCenter environment and how many objects or virtual machines where using each policy.
I saw this as an excuse to refresh my PowerShell skills and wrote a quick function.
Source code can be found on my GitHub, here. Check there for any updates but below is the code at the time of writing.
function Get-vSANSPSummary {
<#
.SYNOPSIS
Export vSAN Storage Policy Information.
.DESCRIPTION

Write-Host "An error occurred!" -ForegroundColor Red
Write-Host $_ -ForegroundColor Red

}
Output currently as a basic HTML table but you could change this to add some ‘HTMLness’ or output to CSV.
As always, thanks for reading and I hope this has been useful to someone.
