You must have a minimum of 11 drives with the same drive type (HDD or SSD).
Shelf loss protection requires that the drives comprising the pool are located in at least six different drive shelves and there are no more than two drives in a single drive shelf.
Drawer loss protection requires that the drives comprising the pool are located in at least five different drawers and the pool includes an equal number of drive shelves from each drawer.
When configuring an AB6100 or AB3100 storage system, make sure each controller has access to an equal number of drives in the first 12 slots and an equal number of drives in the last 12 slots. This configuration helps the controllers use both drive-side PCIe buses more effectively. Currently SANtricity System Manager allows for drive selection under the Advanced feature when creating a volume group. For pool creation, it is recommended to use all drives in the storage system.

Steps

Select Storage > Pools & Volume Groups.
Click Create > Pool.

The Create Pool dialog box appears.
Type a name for the pool.
Optional: If you have more than one type of drive in your storage system, select the drive type that you want to use.

The results table lists all the possible pools that you can create.

Select the pool candidate that you want to use based on the following characteristics, and then click Create.

Characteristic

Use

Free Capacity

Shows the free capacity of the pool candidate in GiB. Select a pool candidate with the capacity for your application’s storage needs.

Preservation (spare) capacity is also distributed throughout the pool and is not part of the free capacity amount.

Total Drives

Shows the number of drives available in the pool candidate.

SANtricity System Manager automatically reserves as many drives as possible for preservation capacity (for every six drives in a pool, SANtricity System Manager reserves one drive for preservation capacity).

When a drive failure occurs, the preservation capacity is used to hold the reconstructed data.

Drive Block Size (AB3100 and AB6100 only)

Shows the block size (sector size) that the drives in the pool can write. Values may include:

512
512-byte sector size.
4K
4,096-byte sector size.

Secure-Capable

Indicates whether this pool candidate is comprised entirely of secure-capable drives, which can be either Full Disk Encryption (FDE) drives or Federal Information Processing Standard (FIPS) drives.

You can protect your pool with Drive Security, but all drives must be secure-capable to use this feature.
If you want to create an FDE-only pool, look for Yes - FDE in the Secure-Capable column. If you want to create a FIPS-only pool, look for Yes - FIPS or Yes - FIPS (Mixed). "Mixed" indicates a mixture of 140-2 and 140-3 level drives. If you use a mixture of these levels, be aware that the pool will then operate at the lower level of security (140-2).
You can create a pool comprised of drives that may or may not be secure-capable or are a mix of security levels. If the drives in the pool include drives that are not secure-capable, you cannot make the pool secure.

Enable Security?

Provides the option for enabling the Drive Security feature with secure-capable drives. If the pool is secure-capable and you have created a security key, you can enable security by selecting the check box.

The only way to remove Drive Security after it is enabled is to delete the pool and erase the drives.

DA Capable

Indicates if Data Assurance (DA) is available for this pool candidate. DA checks for and corrects errors that might occur as data is transferred through the controllers down to the drives.

DA is enabled if all drives are DA-capable. DA may be disabled after the volume is created by selecting Storage > Volumes > View/Edit Settings > Advanced > Permanently disable data assurance. If DA is disabled on a volume, it cannot be re-enabled.

Resource Provisioning Capable (AB3100 and AB6100 only)

Shows if Resource Provisioning is available for this pool candidate. Resource Provisioning is a feature available in the AB3100 and AB6100 storage systems, which allows volumes to be put in use immediately with no background initialization process.

Shelf Loss Protection

Shows if shelf loss protection is available.

Shelf loss protection guarantees accessibility to the data on the volumes in a pool if a total loss of communication occurs with a single drive shelf.

Drawer Loss Protection

Shows if drawer loss protection is available, which is provided only if you are using a drive shelf that contains drawers.

Drawer loss protection guarantees accessibility to the data on the volumes in a pool if a total loss of communication occurs with a single drawer in a drive shelf.

Volume Block Sizes Supported (AB3100 and AB6100 only)

Shows the block sizes that can be created for the volumes in the pool:

512n
512 bytes native.
512e
512 bytes emulated.
4K
4,096 bytes.
