The following tables show the recommended cache capacity when all volumes in the storage system have capacity saving enabled (simplest case).

Table 1: For

Total capacity of DRD-VOLs* (Effective Capacity)	Recommended cache capacity (each CLPR)
	VSP G200	VSP G400	VSP G600	VSP G800
Less than 4TiB	28GiB	28GiB	28GiB	28GiB
4TiB or more	20GiB+X	20GiB+X	20GiB+X	20GiB+X
7.5TiB or more	35GiB	20GiB+X	20GiB+X	20GiB+X
16TiB or more		24GiB+X	24GiB+X	24GiB+X
31TiB or more		86GiB	24GiB+X	24GiB+X
48TiB or more			32GiB+X	32GiB+X
90.5TiB or more			213GiB	32GiB+X
96TiB or more				40GiB+X
160TiB or more				48GiB+X
201.5TiB or more				451GiB
X is the total capacity of DRD-VOLs x 0.2% * DRD-VOL: data reduction volume, which is a DP-VOL with capacity saving enabled.
