Cache capacity with capacity saving-enabled V-VOLs

I/O operations for capacity saving requires access to cached metadata. Metadata cache uses the same CLPR as the cache of user data.

The following table lists recommended cache capacity when all volumes in a storage system are capacity saving-enabled V-VOLs.

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.
