VMware ESX – Install VMware ESX on SATA Disk

If you want a really comprehensive solution, check out the VI Power Documenter. It may be overkill for you though.

Here is a PowerShell script which will grab most of the info you were looking for and export to a CSV which you can easily work with in Excel of course.

param ( $Path )
Connect-VIServer -Server MyVIServer
$HDPrimarySize = @{
    Name = "Primary HD Size (GB)"
    Expression = { $_.HardDisks[0].CapacityKB / 1MB }
}
$AvgMemUsage = @{
    Name = "Mem Usage (Daily Avg %)"
    Expression = { ($_ | Get-Stat -Stat mem.usage.average -MaxSamples 1 -ErrorAction SilentlyContinue ).Value }
}
$vm = Get-VM
$output = $vm | Select-Object Name, MemoryMB, NumCpu, $HDPrimarySize, $AvgMemUsage 
$output | Export-Csv -NoTypeInformation -Path $Path

You can share disks in VMware ESX by editing the properties of the SCSI controller for "virtual" or sharing mode. This will allow you to access the same LUN/disk from two different virtual machines.

This will not allow you to have one system using it R/W and the other R/O. It is designed for use in clusters with cluster aware filesystems.
