Mike,
IMHO you talk about EAV in DS8000, but not about EAV.
EAV Volume (*) can be up to ~1TB big, but chunk size of 1113 cylinders
is for DS8000 family, AFAIK.
Space above 65520 cyl. is called EAS and from z/OS point of view the
smallest chunk is 21 cylinders.
So, you can allocate 1 track dataset on "lower part" of EAV, but in EAS
the smallest space occupied by dataset is 21 cylinders.
(*) I'm sorry for the pleonasm. It's like ATM machine.

Volumes have gotten bigger. The first 64K Cylinders (Mod 54) remain
the same, but EAV space past that can be added in 1113 cylinder chunks
to a multipile of 1113 cylinders. 250GB first step then 1000GB (or
so).

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.
Thanks,
Steve Estle
