Room for improvement:
Slide graphic and notes make no mention about the capabilities of the SATA AHCI adapters, introduced in vSphere 5.5.Correct:
According to the "Configuration Maximums for VMware vSphere 5.5" document, you can configure up to the following:
Devices can be either CD-ROM or disks.
- Virtual SATA adapters per virtual machine: 4
- Virtual SATA devices per virtual SATA adapter: 30
Configuration Maximums for VMware vSphere 5.5.Info:
The "vSphere Virtual Machine Administration" guide - "Configuring Virtual Machine Hardware in the vSphere Web Client" chapter - "SCSI and SATA Storage Controller Conditions, Limitations, and Compatibility" paragraph offers more information.
Each virtual machine can have a maximum of four SCSI controllers and four SATA controllers.
If you add a SATA controller, you can reassign an existing or new hard disk or device to that controller. For example, you can assign the device to (1:z ), where 1 is SATA controller 1 and z is a virtual device node from 0 to 29. For SATA controllers, you can use device nodes 0 through 29, including 0:7.
Last sentence, referring to device node 0:7, stating it can be used to allocate virtual disks to a SATA controller, is opposed to SCSI controllers where node 0:7 is by default assigned to the virtual SCSI controller itself.Source:
