RE: Force fed LPAR

["McGivern, Tom" <Tom.McGivern@xxxxxxx>]

It all depends on WHY you are considering Lpar...  If you can run it on
a single Lpar (or system), then great.
I'm reading through the thread of folks who have consolidated 15 systems
into 1..
We have an 830, with 4 lpars...  One in english, 2 in DBCS (Simpl. And
trad. Chinese), 1 boot.
Now, you say you can have Multiple DBCS languages on a single system...
But it's not supported with JDE OW.

We'll be adding an additional Lpar for another english system, not
because it technically can't fit with the other english, but that we'd
be running everyone from Austrailia, Mexico, US, and Europe all on one
system.  This limits our outage window for backups and PTFs, and thus,
LPAR increases uptime from a user perspective.

So.. Timezones.. .Languages..  Lpar answers our needs...

Could we do this across multiple systems?  Yes.. But since we're dealing
with timezones.. When Austrailia is in their backup window... I can
swing the processors/memory over to the US/Europe Lpar..   Same with
China, Taiwan..
Lpar has worked great for us...

Any additional disk you say?  Well, some for the LIC and OS.. But what's
the cost of an 8GB disk, 4K?
The tape controller IOP is switched between the lpars.. No additional
cost  (where if it were separate systems it would cost us... So in this
since, we're saving money..)


We're looking at upgrading to the 890, 8 lpars...

Maybe it's not for everybody, but I'm very pleased with it.  If they
could only get the Z-series Prism logic to dynamically adjust CPU
allocation..

IBM is really pushing LPAR.  Probably for a number of reasons.
A)  It sells disk and more cards.
B)  It increases complexity of your operation, thus perhaps selling
services.
C)  It drastically increases the amount of your downtime.  Perhaps
selling High Availability solutions, which may help sell services.  For
instance, if I run 4 partitions on V5R2 and I want to go to the next
release, won't I have to do 4 upgrades?  IBM charges $3,500 a upgrade
therefore wouldn't they get 4 times what they would have gotten out of a
single partition machine?  Granted, we do our own upgrades, but I don't
think you can upgrade all partitions at once.

We've recently consolidated multiple machines onto one.  IBM's
insistence that we use LPAR to 'reduce cost' of some of their products.
Their insistence that we run LPAR if we want to currently run the latest
and greatest Domino, Sametime and Quickplace on one iSeries.  And other
attempts to ram LPAR down our throats is upsetting.
