where
•
calculated-entire-capacity-of-a-CV(slots) means the entire capacity of a CV
if the data protection level is set to the Enhanced mode on the SATA drive.
Management area capacity of a mainframe volume
Management area capacity (cyl) Emulation type
7 3380-3, 3380-3A, 3380-3B, 3380-3C,
7 cyl per 1,113 cyl 3390-A
6 3390-3, 3390-3R, 3390-3A, 3390-3B, 3390-3C
0 3390-V
25 3390-9, 3390-9A, 3390-9B, 3390-9C
23 3390-L, 3390-LA, 3390-LB, 3390-LC
53 3390-M, 3390-MA, 3390-MB, 3390-MC
5 3390-1
Notes:
• The management area capacity of a mainframe volume is expressed in cylinders (Cyl).
•
For a Compatible FlashCopy SE volume with a 3390-A emulation type, if you specify a value between 1 and
40,068 cylinders, the space required equals the sum of the specified value and 252 of 40,069 cylinders or more,
calculate the required free space with this formula:
40,320 cylinders + the value rounded up after the decimal point of *A × 1,120 cylinders
where *A = (the specified value - 40,068) ÷ 1,113 cylinders
Boundary values for RAID levels (Enhanced mode on SATA drives)
Boundary value (KB) Emulation type
RAID 6 (14D+2P) RAID 6 (6D+2P) RAID 5 (7D+1P) RAID 5 (3D+1P) RAID 1 (2D+2D)
103,936 22,272 25,984 5,568 1,856 3390-xx
Notes:
•
xx indicates one or more numbers or letters.
•
Boundary values are expressed in kilobytes.
• A SATA drive supports 3390-xx emulation types for a mainframe system.
•
Boundary values for RAID levels (other than Enhanced mode on SATA drives)
Boundary values of external volumes are always one slot, regardless of RAID levels.
Boundary value (KB) Emulation type

Notes:
•
xx indicates one or more numbers or letters.
