David:
Thanks!
The search on IBM.com was hopeless and google was the same.
The book chapter didn't answer all my questions directly but enough
to go back to the originator and assure him it is not an issue.

Ed,
If you are speaking of the new zEC12, with the Flash Express
option, A couple things come to mind, but I have no direct
knowledge because we don't have Flash Express.
- It is a feature code of the zEC12. So only IBM parts, no OEM
- Since it is a feature code of the zEC12, it would be covered
under the same maintenance as any other part of the processor.
- requires z/OS 1.13+maint to exploit
There is fault tolerance built in, and replacement can be done
concurrently. At this time, I am pretty sure that the only
exploiters are PAGING and Dump Services. I hear of other plans,
but don't know if those have been implemented yet.
Here is a link to the redbook zEC12 Technical Guide(see Appendix
C). It pretty much appears to answer all your questions: http://

Subject: Re: Flash Cards on MVS
I got one civil reply offline. The uncivil one from eastern Europe
is not worth the courtesy of a reply.
I will attempt to rephrase the question(s) below.
I have a customer that is looking at the most current IBM system.
I do not have contact with anyone that has the most current IBM
system, so I am asking the group nicely, several questions.
These are more operations (IMO) issues questions and figured the
group would have the knowledge to reply.
I did google and really didn't come up with any answers pertaining
to IBM's MF implementation of Flash cards.
Has anyone have experience with implementing IBM's (NOT STK or OEM)
flash cards.
What is the typical longevity of IBM's Flash cards and do you keep
a few around just in case or ?
IF/when they reach their end of life do you toss them return them
to IBM etc... (how many spares do you keep on hand) How does your
company handle replacements ie operations (or another
group) handles the insertion and taking out of "old" cards.
IOW operations side of the of the handling.
Thanks in advance for any information.
