Note
If you are running vSphere 6.0, please skip this section and refer to the Tagging disks as SSDs in vSphere 6.0 recipe in Chapter 9, VSAN 6.0, if you need to tag your disks as SSDs.
Depending on the type of storage controller you are using, you may need to tell ESXi which disks are your solid-state drives. If your storage controllers present disks to the ESXi as a RAID-0 device, you will need to follow this recipe to inform ESXi about which disks are your SSDs. This recipe must be followed if devices that you know to be SSDs are detected as non-SSDs.
