Working with Flash Devices 15
In addition to the regular storage hard disk drives (HDDs), ESXi supports flash storage devices.
Unlike the regular HDDs that are electromechanical devices containing moving parts, the flash devices
use semiconductors as their storage medium and have no moving parts. Typically, the flash devices are
resilient and provide faster access to data.
To detect flash devices, ESXi uses an inquiry mechanism based on T10 standards. Check with your
vendor whether your storage array supports the ESXi mechanism of flash device detection.
After the host detects the flash devices, you can use them for several tasks and functionalities.
