Cluster overview with capacity

Wednesday, 17 June 2009 16:56

@Depping asked me to send an overview of our current capacity, both hosts in clusters and storage. In half an hour I scripted this powershell script. This one checks all you clusters and hosts within, calculate the total available GB, GHz and in the end of the report, an overview of the datastores is presented (from John Tuffin's Blog)

Here is the script:

$VC = Connect-VIServer "<your vCenter Server here>"
$grandtotalGB = 0
$grandtotalGHz = 0
$Clusters = Get-Cluster -Location "<If needed, else delete it from -Location>" | sort name
foreach ($Cluster in $Clusters) {
$TotalGB = 0
$TotalGHz = 0
 
$ESXHosts = $Cluster | Get-VMHost | sort name
Write-Host $Cluster.name
foreach ($ESXHost in $ESXHosts) {
$ESXHostProp = $ESXHost | get-view
$ESXTotalGHz = [Math]::round($ESXHostProp.Hardware.CpuInfo.Hz/ 1GB) * $ESXHostProp.Hardware.CpuInfo.NumCpuCores
$ESXTotalGB = [Math]::round($ESXHostProp.Hardware.MemorySize/ 1GB)
$TotalGHz = $TotalGHz + $ESXTotalGhz
$TotalGB = $TotalGB + $ESXTotalGB
Write-Host " " $ESXHost.name ": Total GHz:" $ESXTotalGhz "- Total GB:" $ESXTotalGB
}
$TotalAvailableGB = $TotalGB-$ESXTotalGB
$TotalAvailableGHz = $TotalGHz-$ESXTotalGHz
Write-Host "Total GB =" $TotalGB
Write-Host "Total Available GB (n-1) =" $TotalAvailableGB
Write-Host "Total GHz =" $TotalGHz
Write-Host "Total Available GHz (n-1) =" $TotalAvailableGHz
Write-Host "-------------------------------------------------------------------"
$grandtotalGB = $grandtotalGB + $TotalAvailableGB
$grandtotalGHz = $grandtotalGHz + $TotalAvailableGHz
}
Write-Host "Total Available Memory : $grandtotalGB GB"
Write-Host "Total Available CPU : $grandtotalGHz GHz"
Get-Datastore | sort name | ft name,@{ Label = "FreespaceGB"; Expression = { [Math]::round($_.FreeSpaceMB * 1MB / 1GB) } }, @{ Label = "CapacityGB"; Expression = { [Math]::round($_.CapacityMB * 1MB / 1GB) } }

Did you know: that the limit on vCPUs per core has been raised from 8 (or 11 for VDI workloads) to 20. That means you can use all the power in the latest processor technologies!
