S3029: A History of Storage Management.
SHARE Technical Conference
Ever wonder what storage management was like before System Managed Storage (SMS)? This session will explore the early origins of storage management (all the way back to 1965!). Experiences starting with punch cards, tape, IBM 2311/2314 disks, working through the IBM 3390's will be covered. How storage management was done before SMS was introduced and how SMS changed that will be discussed. The Texas Education Agency was the first site in Austin, Texas to implement SMS. Due to strong data set naming conventions already being in place, this was done with minimal non-technical management involvement.
The author has been writing programs since 1965 in Fortran, COBOL,
PL/1, Algol, Pascal, C, C++, and various assembly languages. He was the MVS Security and Data Managment (later renamed Storage Management) SHARE project leader for twelve years.
He "retired" from the Texas Education Agency in 1995 as Senior Directory for Systems Support.
