You can calculate the number of HTI pairs you can create based on the snapshot estimated manageable capacity.
To view the snapshot estimated manageable capacity in HDvM - SN, see Viewing local replication summary information.
Calculate the number of HTI pairs that you can create using the following formulas, where SM refers to shared memory:
Number of HTI pairs that you can create =
Snapshot estimated manageable capacity / Snapshot management capacity in a P-VOL
Snapshot estimated manageable capacity in a P-VOL [GB] =
(P-VOL capacity of HTI pairs [TB] / 2.6) * 3,024 + (168 * 2 (consumed shared memory [GB]))
