PowerCLI: Configuring an All-Flash vSAN

From my understanding all-flash vSAN works like this:
Caching Tier is 100% Writes. (Write Buffer)Capacity Tier is Mixed-Use With this in mind, I ordered Dell R730's w/ two types of drives.  Two high write endurance SSD's and Four Mixed Use SSD's.
Short Story:
Here is the script I created to 'tag' the mix-use drives as flash capacity: #Enable All Flash vSAN Intelligently Add-PSSnapIn -Name VMware.VimAutomation.Core -ErrorAction SilentlyContinue $TargetHosts = Get-VMHost $CacheDiskVendor = "TOSHIBA" $CacheDiskModel = "PX02SSF040" $CapacityDiskVendor = "TOSHIBA" $CapacityDiskModel = "PX02SMF040" Foreach ($VMhost in $TargetHosts) { $ESXCLI = $VMHost | Get-ESXCLI $Storage = $VMhost | Get-VMHostStorage Foreach ($SCSILUN in $Storage.ScsiLun) { If ($SCSILUN.Vendor -match $CapacityDiskVendor -and $SCSILUN.Model -match $CapacityDiskModel) { $$SCSILUN.Cano…

PowerCLI: Configure/Enable Remote Syslog

If False, then it will append. $Replace = $true #If ConfirmPreference is set to true, this script will ask you on every single host whether you want to make the change. Set to $False, if you just want it to do it. $ScriptConfirmPreference = $false ## Don't modify from here ## $AdvancedSettings= $VMHosts | Get-AdvancedSetting| where {$ -match "…
