You can create a pool manually (from a set of candidates) if the Pool Auto Configuration feature does not provide a pool that meets your needs.

A pool provides the logical storage capacity necessary from which you can create individual volumes that can then be used to host your applications.

Before you begin
  1. Select Storage  Pools & Volume Groups.

  2. Click Create  Pool.

    The Create Pool dialog box appears.

  3. Type a name for the pool.

  4. Optional: If you have more than one type of drive in your storage array, select the drive type that you want to use.

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

  5. 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.

    System Manager automatically reserves as many drives as possible for preservation capacity (for every six drives in a pool, 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 (DE6400 and DE6600 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.


    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 (DE6400 and DE6600 only)

    Shows if Resource Provisioning is available for this pool candidate. Resource Provisioning is a feature available in the DE6400 or DE6600 storage arrays, 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 (DE6400 and DE6600 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.
