IBM i Integrated File System (IFS) Bootcamp

The integrated file system (IFS) is a part of the IBM i operating system that supports stream input/output and storage management similar to personal computer and UNIX operating systems, while providing an integrating structure over all information stored on your system. The IFS has been a part of the operating system since 1994, however many systems administrators new to IBM i are often confused about how best to access, organize, secure, and performance tune this critical piece of IBM i.  

This bootcamp consists of six video lessons and a complimentary set of session slides.  All sessions were recorded live at the COMMON POWERUp conference in Denver, Colorado from April 24 to 26, 2023.  All lessons are presented by Margaret Fenlon, the team leader for the integrated file system and servers team at IBM Rochester

This bootcamp is being provided at no charge to COMMON members through a generous sponsorship from Fortra.
