How to reconfigure storage controllers in the Server Setup GUI
For optimal I/O performance, it is advisable to spread the LUNs presented to Delphix over multiple controllers. Delphix will automatically stripe across the LUNs that are presented so balancing the number of LUNs per controller will help reduce contention.The process of changing your storage configuration to use multiple SCSI controllers is relatively simple but will require bringing down the Delphix Engine.
NOTE: Is in important not to reassign the root disk. If you have any question about which disk that is, please contact Delphix Support before trying this procedure.
1.Log into the Server Setup GUI using sysadmin credentials
2.Stop all VDBs and shut down Delphix Engine from the Server Setup screen:
3. Access vSphere for the ESX host that the Delphix Engine is on and select the Delphix host.
4. Make sure that the Delphix host has stopped and select Edit Settings on the Summary page:
5. In the Virtual Machine properties, select any disk other than the root disk move it to a different SCSI controller. The controller is denoted by the first of the two numbers in the parenthesis. Continue doing this until you have the drives spread across the available SCSI controllers.
6. Once the drives have been set up to your satisfaction, select OK and you can start the host again. Delphix should automatically discover your changes when you boot up and you'll be able to see the controllers from the Server Setup page:
