Hello,

Please see if this helps:

It might be a good idea to talk with your storage admins as they may already have something you can use - many systems have a process that performs space calculation for the dasd models being used.
Hope this helps,

Hello,

Dividing the number of records expected by the number that will fit on one track gives the number of tracks required.

Divide by 15 (and round up) to find the number of cylinders required.
Hope this helps,
