the differences between "Basic Storage Devicec" and "Specialized storage Devices":
Basic Storage Devicec:
The installer automatically detects any locally attached storage
devices, and displays the Storage Device Warning window that asks
you to choose whether to discard or keep existing data on those
devices.
Specialized storage Devices:
The installer displays the Storage Devices Selection window with
tabs for each of the supported device types. You can select the
devices on which to install the operating system in addition to any
drives that the system should mount automatically. To configure
iSCSI or FCoE connections, click Add Advanced Target. You can
filter storage devices by WWID or by a combination of port, target,
and LUN.
