You can add a VMware Paravirtual SCSI high performance storage controller to provide greater throughput and lower CPU utilization.
About this task
VMware Paravirtual SCSI controllers are best suited for environments, especially SAN environments, that run I/O-intensive applications.
Verify that the virtual machine has a guest operating system with VMware Tools installed.
Verify that the virtual machine has hardware version 7 or later.
Familiarize yourself with VMware Paravirtual SCSI limitations. See vSphere Virtual Machine Administration .
To access boot disk devices attached to a VMware Paravirtual SCSI controller, verify that the virtual machine has a Windows 2003 or Windows 2008 guest operating system.
In some operating systems, before you change the controller type you must create a virtual machine with an LSI Logic controller and install VMware Tools.
Power off the virtual machine.
- Click Virtual Machines in the VMware Host Client inventory.
- Right-click a virtual machine in the list and select Edit settings from the pop-up menu.
- On the Virtual Hardware tab, click Add other device and select SCSI Controller from the drop-down menu.
The new SCSI Controllers appears in the Hardware list.
