If you intend to create pairs with volumes of different emulation types, the maximum number of pairs

you can create depends on the following conditions.

NOTE:

For more information about calculating total number of differential tables per pair, see Table 2.

Calculating the number of BC pairs if LUSE is not used

Use the following equation to calculate whether the desired number of BC pairs can be created:

{( ) x (number of BC Pairs)} ( ), where:

• ( ) is the required number of differential tables per pair (see Table 2).

• (number of BC pairs) is the number of BC pairs you want to create.

•

( ) is number of differential tables in the disk array.

•

( ) = 13,652 when additional shared memory for differential tables is not installed.

•

( ) = 30,718 when additional shared memory for differential tables is installed.

For example, if you create 10 pairs of OPEN-3 volumes and 20 pairs of OPEN-V volumes in a disk

array that does not have additional shared memory for differential tables, use the following equation:

1 x 10 + 193 x 20 = 3870 13,652
