The following are the disk media types recognized by SFW:
: Stands for a hard disk drive which is used for storing and retrieving primary computer data. By default, all disks, unless auto-discovered as SSD, are recognized as HDD media type.
: Stands for a solid-state drive, also known as solid-state disk or a flash drive which is a data storage device used either for storage administration or as a caching device.
To manage environments containing both SSD and HDD storage devices, identify and classify them using the Volume Manager.
With this feature, you can set, change and display the media type information of the SSD disks. Once the disk is classified as SSD it is used in all space allocation operations, across nodes, restarts and failover, provided it is part of an SFW dynamic disk group.
Alternatively, you can use SSDs in a storage environment as caching devices using the SmartIO feature.
