FORMULA METHOD OF COMPUTING FBA-BLOCK REQUIREMENTS ON IBM FIXED-BLOCK-ARCHITECTURE
Abstract
A formula has been derived tht permits computation of the
number of FBA-blocks required for a file stored on an IBM disk
that uses fixed-block architecture. Previously only an involved
algorithm, released by IBM, was available for this task. Both
formula and the algorithm involve the use of control intervals. Control
intervals are of fundamental importance with IBM file systems
since they permit disk independent program manipulation of large computer
files and data bases.
