Neil,
We have it both ways in various accounts. We used to separate for
performance, but with today's large CPW numbers, we haven't really had the
need. Don't forget, you can also run these partitions uncapped, thereby
having the CPW move to each partition when required. Unfortunately, not yet
with memory. Domino likes memory.
I think the big reason for putting domino in a separate partition
is that you can leave the email side open to the internet, but keep your
application partitions off the internet.

Subject: Native Domino - to LPAR or not to LPAR, that is the question.
What is the general consensus on whether or not you need (or should) run
Domino (for email & Sametime) in a separate LPAR? I can't really think of a
lot of advantages, just disadvantages like:
- more maintainance on the LPAR for release upgrades, PTF's, etc.
- a more expensive system because of the LPAR driving requirements for
additional disk controllers and disk, driving a requirement for an otherwise
unneeded expansion unit, etc.
- more PC server like in that you end up with unused processor and disk
resources that would be better utilized if Domino was running in teh main
system/partition.
I can't think of any cases where errors in Domino would cause a production
system/partition to crash - but has anyone experienced that ?
