VMAX Thin Provisioned Frame Performance analyze
A.The key performance indicator is IO Density and they should looks at it 2 ways.
B. Relative numbers. If EFD is > than FC and > SATA, then data placement and FASTVP is being effective.
C. And then look at the IO Density per tier. When EFD or FC gets too high, they need to add spindles. If SATA is too high and there is space left in FC and EFD, then they probably have some policy adjustments needed or something else going on.
D. The absolute planning or threshold number will vary by drive size, speed, etc.
