Smart Setup Wizard
The Smart Setup Wizard simplifies the creation of Thin Provisioning Pools and configuration of host affinity for
configurations enabled with Thin Provisioning.
For the procedure on configuration using the
Smart Setup Wizard, refer to "Configuration Guide (Basic)".
Note
If a Thin Provisioning Pool has not been created, the
Smart Setup Wizard automatically creates one. The
Thin Provisioning Pool configuration is automatically determined based on the type and number of
installed drives.
• The priority for selecting drive types is as follows.
SSD > SSD SED > SAS > SAS SED > Nearline SAS > Nearline SAS SED
If multiple drive types exist, the drive type with the highest priority is selected to create a Thin
Provisioning Pool.
To create another Thin Provisioning Pool with the unselected drive types, this wizard cannot be used.
Use the dedicated function provided by this storage system to create a Thin Provisioning Pool.
• The RAID levels and the number of drives for RAID groups that configure the Thin Provisioning Pool are
as follows.
Drive type RAID level Number of drives
SSD and SSD SED RAID5 Five or more
SAS, SAS SED, Nearline SAS, and Nearline SAS SED RAID6 Seven or more
• A Global Hot Spare is registered for each Thin Provisioning Pool.
The following shows an example of creating a Thin Provisioning Pool using the Smart Setup Wizard.
● For SSDs and SSD SEDs
RAID groups are created with RAID5, which has high storage efficiency.
Table 54
shows a guideline for the number of drives and user capacities when 1.92TB SSDs are installed and
Figure 62 shows an example RAID configuration.
