RE: Do IBM or BPs sell pre-partitioned new systems? -- MIDRANGE-L

Roberto:

A virtual HMC is still an HMC, and still connects to the ASMI via the FSP.

There are only two ways of managing partitions. HMC or IVM/VPM. I will
admit that PowerVC and a couple of other products IBM has can do it as well,
but the HMC is what we see 98% of the time unless the customer has mixed
UNIX and IBM i workloads, or is running a cloud service.

Any way you cut it, running IBM i in a partitioned environment without an
HMC is a questionable endeavor without at least having thought the
infrastructure and ramifications through. And DR is the most important part
to consider, since no one ever loses power for longer than the UPS/generator
set can run. (ask our friends that recently had hurricanes come through
about that issue)

Take into account that alternatives to the physical HMC DO exist and your BP
should know about them. You have the Virtual HMC which you can install into
most any VM-Host and you can also use the integrated virtualization manager
(a VIOS partition with a bolted-on webserver that does most of the stuff you
use the HMC for)...

Okay. Thanks for your response.

Yea they do. All the time.

Running a partitioned POWER box without an HMC is just not an informed
decision. Granted VPM will work, but again, yuck, and the number of

CEs

that are out there that have a clue how to swap a part out with VPM
is shockingly low.

Then how do you manage the system?

By "manage the system", are you asking about changing partition
configurations? If so, then I'd ask why change them? Why not live
with

how

they might be configured originally?

Say you want an IBM i partition and a Linux partition, and you don't
anticipate changing that.

Just because the partitions are called for on the configuration does
not

create them, nor build them. Even the preload configuration option

totally useless in most cases.

You might want to think that all the way through before you try it.

That is my reason for posing the question. If I understand
correctly, the answer is no. It appears that neither IBM, nor BPs
will pre-configure multiple partitions on new orders.
