$servername = "ROGUE"

$server = New-Object "Microsoft.SqlServer.Management.Smo.Server" $servername

$server | 
Select-Object IsClustered, ClusterName, 
FilestreamLevel,
IsFullTextInstalled,
LinkedServers,
IsHadrEnabled,

• Are there any configured linked servers in the system (LinkedServers)?
• Is AlwaysOn enabled (IsHadrEnabled) and are any availability groups configured (AvailabilityGroups...
