Select the storage type
When you first access the wizard, you are prompted to select the type of storage to use for your environment.
Read through the options and make your selection, and then click Next to proceed.
Virtual storage supports the following features:
Tiering
Snapshots
Replication
Thin provisioning
One pool per installed RAID controller and up to 16 disk groups per pool
Maximum 1 PB usable capacity per pool with large pools feature enabled
RAID levels 1, 5, 6, 10, and ADAPT
Adding individual disks to increase RAID capacity is only supported for ADAPT disk groups
Capacity can be increased by adding additional RAID disk groups
Page size is static (4 MB)
SSD read cache
Global and/or dynamic hot spares
Linear storage supports the following features:
Up to 32 pools per installed RAID controller and one disk group per pool
RAID levels 0, 1, 3, 5, 6, 10, 50, ADAPT, and NRAID
Adding individual disks to increase RAID capacity is supported for RAID 0, 3, 5, 6, 10, 50, and ADAPT disk groups
Configurable chunk size per disk group
Global, dedicated, and/or dynamic hot spares
NOTE: Dell EMC recommends using virtual storage.
NOTE: After you create a disk group using one storage type, the system will use that storage type for additional disk
groups. To switch to the other storage type, you must first remove all disk groups.
Creating disk groups and pools
The panel that is displayed when creating disk groups and pools is dependent upon whether you are operating in a virtual
storage environment or a linear storage environment.
Virtual storage environments
If you are operating in a virtual storage environment, the system scans all available disks, recommends one optimal storage
configuration, and displays the suggested disk group layout within the panel.
In a virtual storage environment, the storage system automatically groups disk groups by pool and tier. The disk groups also
include a description of the total size and number of disks to be provisioned, including the configuration of spares and unused
disks.
If the system is unable to determine a valid storage configuration, the wizard lists the reasons why and provides directions on
how to achieve a proper configuration. If the system is unhealthy, an error is displayed along with a description of how to fix it.
Follow the recommendations in the wizard to correct the errors, then click Rescan to view the optimized configuration.
For a system with no pools provisioned, if you are satisfied with the recommended configuration, click Create Pools to
provision the system as displayed in the panel and move on to attaching hosts. For a system that contains a pool, if you are
satisfied with the recommended configuration, click Expand Pools to provision the system as displayed in the panel.
If your environment requires a unique setup, click Go To Advanced Configuration to access the Create Advanced Pools panel.
Select Add Disk Group and follow the instructions to manually create disk groups one disk at a time. Select Manage Spares and
follow the instructions to manually select global spares.
Linear storage environments
If you are operating in a linear storage environment, the Create Advanced Pools panel opens.
Select Add Disk Groups and follow the instructions to manually create disk groups one at a time. Select Manage Spares and
follow the instructions to manually select global spares. Click the icon for more information about options presented.
