FTRP Thresholds
There are two FTRP usage thresholds: Attention and Warning.
Table 22 FTRP Thresholds
Threshold Selectable range Default Setting conditions
Attention 5 (%) to 80 (%) 75 (%)
Attention threshold £ Warning threshold
The "Attention" threshold can be omitted.
Warning 5 (%) to 99 (%) 90 (%)
•
FTV Thresholds
There is only one FTV usage threshold: Attention. If there is insufficient capacity for the FTV unallocated space
in the pool free space, an alarm notification is sent. The threshold is determined by the ratio of free space in
the FTSP and the unallocated FTV capacity.
Table 23 FTV Thresholds
Threshold Selectable range Default
Attention 1 (%) to 100 (%) 80 (%)

When the Flexible Tier function is enabled,
32 work volumes (physical capacity is 0MB) are created. The
maximum number of volumes that can be created in the ETERNUS AF decreases by the number of work
volumes that are created.
•
The FTRP capacity that can be used for VVOLs differs from the maximum Thin Provisioning Pool capacity. For
details, refer to "VMware VVOL" (page 115).
