Free Capacity
|
Shows the available capacity in GiB. Select a volume group candidate with the capacity for your application’s storage needs.
|
Total Drives
|
Shows the number of drives available for this volume group. Select a volume group candidate with the number of drives
that you want. The more drives that a volume group contains, the less likely it is that
multiple drive failures will cause a critical drive failure in a volume group.
|
Drive Block Size (EF300 and EF600 only) |
Shows the block size (sector size) that the drives in the group can write. Values may include:
- 512 – 512-byte sector size.
- 4K – 4,096-byte sector size.
|
Secure-Capable
|
Indicates whether this volume group 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 volume group with Drive Security, but all drives must be secure-capable to use this feature.
- If you want to create an FDE-only volume group, look for Yes - FDE in the Secure-Capable column. If you want to create a FIPS-only volume group, look for Yes - FIPS in the Secure-Capable column.
- You can create a volume group comprised of drives that might or might not be secure-capable or are a mix of security levels. If the drives in the volume group include drives that are not secure-capable, you cannot make the volume group secure.
|
Enable Security?
|
Provides the option for enabling the Drive Security feature with secure-capable drives. If the volume group is secure-capable and you have
set up a security key, you can enable Drive Security by selecting the check box.
Note: The only way to remove Drive Security after it is enabled is to
delete the volume group and erase the drives.
|
DA Capable
|
Indicates if Data Assurance (DA) is available for this group. Data Assurance (DA) checks for and corrects errors that might occur as data is transferred through the controllers down to the drives.
If you want to use DA, select a volume group that is DA capable. This option is available only when the DA feature has been enabled.
A volume group can contain drives that are DA-capable or not DA-capable, but all
drives must be DA capable for you to use this feature.
|
Resource Provisioning Capable (EF300 and EF600 only) |
Shows if Resource Provisioning is available for this group. Resource Provisioning is a feature available in the EF300 and EF600 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 volume group if a total loss of
communication to a shelf occurs.
|
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 volume group if a total loss of
communication occurs with a single drawer in a drive shelf.
|
Volume Block Sizes Supported (EF300 and EF600 only) |
Shows the block sizes that can be created for the volumes in the group:
- 512n – 512 bytes native.
- 512e – 512 bytes emulated.
- 4K – 4,096 bytes.
