VMware: SATA Controller Support in ESX 3.5 (1008673)

April 4th, 2009 4 comments

ESX 3.5 supports multiple SATA controllers. Some of these controllers are supported only in the native Advanced Host Controller Interface (AHCI)/SATA mode with SATA hard-drive, and some are only supported in IDE/ATA mode with SATA Optical Drive. For other controllers, VMware provides support in AHCI/SATA or IDE/ATA mode on both types of drives, but you need to be aware of certain feature limitations and trade-offs associated with each mode. clip_image005
