A.6 Thin Provisioning Management
• Maximum Pool Capacity
Description
Input condition/
Display contents
The maximum pool capacity that is set by this function is used as a virtual logical capacity in the ETERNUS DX. When
the Thin Provisioning function is enabled, the ETERNUS DX allocates capacity to the physical drives proportionate to
the amount of data that is written to the virtual volume. Therefore, the actual available capacity is limited depend-
ing on the maximum physical capacity of the drives that can be installed in the storage system or the maximum
pool capacity, whichever is smaller. For example, when using an ETERNUS DX200F that is configured only with
800GB SSDs, the actual capacity that can be used is approximately 16TB even if the maximum pool capacity is
"32.00TB".
To reduce the maximum pool capacity, disable "Thin Provisioning". After performing this action, restart this function
to enable "Thin Provisioning", and then set a new "Maximum Pool Capacity".
Select the maximum pool capacity that is specified for the ETERNUS DX.
ETERNUS DX storage systems can expand the maximum pool capacity gradually
according to the used pool capacity. Because the maximum pool capacity is not fixed,
memory can be more effectively used. This item is only available when "Thin
Provisioning" is enabled. Note that a capacity that is smaller than the current capacity
cannot be selected.
