Others have mentioned a number of resources. One of the best resources for details are the IBM Redbooks for Z.
For a high-level summary of functions and features for different generations of z Systems, if can you still get these are the S/390 Reference Guides (I authored these during the period 1995-2005). The Ref Guides were superseded by the IBM Z Functional Matrix (version 1, co-authored by myself): https://www.redbooks.ibm.com/abstracts/redp5157.html?Open [https://www.redbooks.ibm.com/images/thumbs/redp-5157-05_x2.jpg]<https://www.redbooks.ibm.com/abstracts/redp5157.html?Open> IBM Z Functional Matrix | IBM Redbooks<https://www.redbooks.ibm.com/abstracts/redp5157.html?Open> This IBM® Redpaper™ publication provides a list of features and functions that are supported on IBM Z, including the IBM z15™ (z15) - Machine type 8561, IBM z14™ (z14) - Machine types 3906 and 3907, www.redbooks.ibm.com Just to get to grips with the new z alphabet soup (acronyms) I would start with the Functional Matrix:-) Regards Parwez Hamid ________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Steve Estle <sest...@gmail.com> Sent: 18 May 2021 02:41 To: IBM-MAIN@LISTSERV.UA.EDU <IBM-MAIN@LISTSERV.UA.EDU> Subject: Best catch up resources for MVS / ZOS Technologies Hello Everyone in Mainframe Land, I've been out of the mainframe world since about 2001, but spent the prior 20 years immersed in that world working with everything from MVS/370 to MVS/ESA and VM, performance and capacity planning disciplines across a variety of situations in the IT Services and consulting spaces. I, am, now as a "IT Infrastructure Engineer- IBM z/OS Mainframe Engineer" after nearly 20 years of other activities (Project Mgmt, entrepreneur, etc) am about to potentially come back into a new mainframe role and I need to catch up as quickly as possible. Any suggestions on ways to fill in the gaps for ZOS, ZVM, hardware, performance, etc? Bottom line I'm looking for that gap education to as quickly as possible get up to speed with changes in platforms since 2001. If prefer to call - all my info is below.
