VMware SIOC quick configuration in datacenter scale

I'm currently troubleshooting one weird high kernel latency (KAVG) issue and there is a suspicion that the issue can be somehow related to VMware SIOC which is widely use in customer's environment. To confirm or disprove the issue is really related to SIOC we can simply disable SIOC on all datastores and observe if it has positive impact on kernel latency.

Customer has lot of production datastores grouped in datastore clusters so following PowerCLI one liners can help with quick configuration and validation of SIOC settings across whole datacenter.

SIOC current state for all datastores in datastore clusters

 Get-DatastoreCluster | Get-Datastore | select-object name,type,StorageIOControlEnabled | Format-List -Property *  

Disable SIOC for all datastores in datastore clusters

 Set-Datastore (Get-DatastoreCluster | Get-Datastore) -StorageIOControlEnabled $false | select-object name,type,StorageIOControlEnabled

Enable SIOC for all datastores in datastore clusters

 Set-Datastore (Get-DatastoreCluster | Get-Datastore) -StorageIOControlEnabled $true | select-object name,type,StorageIOControlEnabled  

Thanks PowerCLI!
