Figure 12 V-VOL Window
DescriptionItem
Provides the following information about V-VOLs of XP Thin Provisioning:
• used: Total capacity (GB) of V-VOLs associated with Pools.
• remaining: Total capacity (GB) of V-VOLs that can be associated with pools. This
capacity is calculated based on the assumption that V-VOLs of 1024 GB are
associated with pools.
If V-VOLs of another size are associated with pools, calculate the total capacity
of V-VOLs that can be associated with pools from the remaining value by the
following formulas.
X1 = (remaining (GB) 1024)
S1 = (X1 x 14 + (remaining (GB) - (X1 x 1024) ) 84)
S2 = ( ( Capacity of one V-VOL (GB) 84) + 1)
Total capacity of V-VOLs that can be associated with pools = (S1 S2) x
Capacity of one V-VOL:
◦ indicates that the number enclosed by two downward arrows should be
rounded down to the nearest whole number.
◦ indicates that the number enclosed by two upward arrows should be
rounded up to the nearest whole number.
CAUTION: The values of used and remaining are not reflected in the window
until you click the Apply button.
