Smart Setup Wizard

Smart Setup Wizard
The Smart Setup Wizard is a wizard that 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)".
If a Thin Provisioning Pool has not been created, the Thin Provisioning Pool configuration is automatically
determined based on the type of drives and the number of drives installed in the ETERNUS DX.
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
SSD and SSD SED
SAS, SAS SED, Nearline SAS, and Nearline SAS SED
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 36 shows a guideline for the number of drives and user capacities when 1.92TB SSDs are installed and
Figure 64 shows an example RAID configuration.
