RE: What is the difference between Flash storage and a Flash Storage system like the V9000/V7000

All of that stuff is handled in the administrative domain and is replicated
very nicely in real time.

Where it breaks down is if you have an application that must reside in the
*SYSBAS, then the administrative domain won't help. We've gotten around
that with good change control, and remote journaling. Periodically (every
two hours) we do a roll forward with the journals and it catches up. Not
great but for the applications we had in that environment it worked.

This was another thing which was tough for me to get my head around when
considering PowerHA.
Some objects stayed in system asp, a bulk of stuff went to iASP on the SAN.
Replicating the stuff in the system asp, like user profiles, etc seemed like
something bolted on.

For those who may be apprehensive about moving programs and data to an
iASP, I'll share that for us the transition was not too difficult. We've
been hosting our web portal and a portfolio of administrative applications
in an iASP for several month, and we've not experienced any major
concerns.
We did have to tweak an Apache configuration, plus some of our developer
tools and other utilities that set up portal environments to be able to
support iASPs.

A number of configuration objects such as subsystem descriptions, job
descriptions, output queues, etc. need to remain in SYSBAS. Or at least we
were not able to get them to work if we moved them to an iASP.
