Re: 24x7 information

Al,

If I understand the original request correctly, the objective is to
provide backup capability without bring down production.  Not even the
sync time needed for save while active.

Would LPAR allow data mirroring to occur with one partition live for
production and the second partition devoted to mirroring and backup
work?

Granted, natural disasters (fire, flood, etc.) would kill the box, but
with a good backup, a hot site could keep them afloat.  I'm just
thinking that if you have two machines, in the same room, connected by
fiber, if one burns so does the other.

Now I would grant that LPAR gains nothing for the down time required for
upgrades.  IMHO, that is more likely to occur than disaster recovery and
is usually scheduled for normal production downtime.  The request did
say 24/7, but it didn't say 24/7/365.

Just a thought.
