RE: Preparing for HA solution

["Nathan Cheney" <nathan.cheney@xxxxxxxxxxxx>]

Oliver,

As a provider of HA software solutions I can give you some assurance
that we have MANY customers that use their target (stand-by) machine for
many other purposes other than just sitting idle waiting for a disaster
to happen.  

The best setup for a target box is certainly an LPAR environment, but
either situation will work.  Using the system for backups, report
generation, a testing environment, development environment, etc. are all
uses for the target box.  So as to not go into anything sales related
here, let me know if you have any more specific questions about
pre-install and I would be glad to answer any questions you might have.

Thanks,

Nathan Cheney

Subject: Preparing for HA solution


Hi,

after several crashes last year, TPTB finally have agreed to an HA
solution for our
AS/400. 

We'd like to have a hot-standby and be able to switch over in less than
1 hour.
Currently, it looks like DataMirror will be the HA-provider.

We have an 820 (proc.2396) with about 210GB DASD (fully mirrored) at
V5R1.
System is leased until 31Dec. 2003 with full IBM software and hardware
maintenance.

We have been told we should get a hot-standby with similar setup
(CPW-wise).

AFAIK, normal solutions have the stand-by machine sitting mostly idle in
its own,
separate machine room with separate network connection and all that
stuff.
So, could the stand-by machine be used for any real work (maybe LPAR as
a test or
development machine)? 

Are there any reports (in-depth) on how this was done. What are the
upcoming problems?
What should be done in preparation (or can be done)?

Thanks for sharing your experiences,

Oliver
